Full textAbstract:
Onions are a major vegetables in Korea. Short-day onions are grown in more than 95% in southern area of South Korea, and long-day onions are grown above 600-m altitude in the highlands. Onion cultivation in the highland areas has become difficult for farmers to obtain high income but stable production because of higher cost of seed and the intensive labor involved in production. Consequently, onion set culture by inexpensive onion seeds compared with expensive F1 seed has an advantage due to the higher proportion of marketable size bulbs. This study was conducted to find out the suitable sowing time and tray size for onion set culture in the highlands—the earlier the sowing time, the higher the number of onions set. The most appropriate sowing date and 1.6–3.5 g of onion set size was early to middle May, also with the highest distribution percentage. The highest set number (780.8 set/m2) of suitable onion set size (1.6–3.5 g) were harvested from the 288 trays, followed by 770 set from the bed (9 g/m2 of seed sowed), and (7/m2 of seed sowed) in the 406 tray.

Onion is one of the commodities of annual vegetable crops that have high economic value, a type of short-lived plant, can be propagated vegetatively or generatively, can be developed in low to highland areas and can be cultivated throughout the year. High demand for onions was not followed by supply of onion in the market. This is caused by high risks in the cultivation of Onions. As the theory of supply, the level of supply of a commodity will be affected by the amount of commodities produced. The research aims to analyze the risk factors for onion production and onion supply behavior. The method of this research was survey methode. The location of this research was at Tonjong, Kramatwatu subdistrict. The population of onions farmers was 117 farmers and the amount of the sample used in this research is 54 farmers. Sort of datas that used in this research were primary data and secondary data. The analysis data that used are risk analysis, and multiple linear regression analysis. The results showed that the level of risk of onion in Tonjong Village was 1621.91 or 32 percent of the productivity value obtained by farmers. The source of the risks on Onion farming in Tonjong Village are climate and weather, pests and plant diseases, land fertility, and the effectiveness of using inputs. There are two factors that significantly influence the behavior of onion offering in Tonjong Village, the cost variable of fungicide and the variable cost of insecticide.

Onion yield and grade were compared under sprinkler, subsurface drip, and furrow irrigation in 1992, 1993, and 1994. Furrow-irrigated onions were planted on two double rows on 1.12-m-wide beds at 352,000 seeds/ha. Sprinkler- and drip-irrigated onions were planted in nine single rows on a 2.24-m-wide bed at 432,100 seeds/acre. Drip plots had three drip lines buried 0.10 m deep in each 2.24-m bed. Soil water potential at 0.2-m depth was measured by tensiometers and granular matrix sensors (Watermark Model 200SS, Irrometer Co., Riverside, Calif.). Furrow irrigations were started when the soil water potential at the 0.2-m depth reached –25 kPa. Drip-irrigated onions had soil water potential at the 0.2-m depth kept wetter than –25 kPa by daily replacement of crop evapotranspiration (Etc). Sprinkler irrigations were started when the accumulated Etc reached 25 mm. Sprinkler irrigation resulted in significantly higher onion yield than furrow irrigation in 1993 and 1994. Sprinkler irrigation resulted in higher marketable onion yield than furrow irrigation in 1993. Drip irrigation resulted in significantly higher onion yield than furrow irrigation every year. Drip irrigation resulted in higher marketable onion yield than furrow irrigation in 1992 and 1994. Marketable onion yield was reduced in 1993 due to rot during storage.

Full textAbstract:
Onion thrips (Thrips tabaci Lindeman) is a major pest in organic onion production and effective integrated pest management strategies are lacking. Our objective was to evaluate combinations of semi-glossy (“Rossa di Milano” and B5336AxB5351C) and waxy (“Bradley”) onion cultivars with reflective mulch, with or without biopesticides (spinosad + neem oil tank mix), to manage T. tabaci in organic onion production. Thrips densities were assessed weekly and bulbs graded and weighed at harvest. Onions sprayed with spinosad + neem oil had fewer T. tabaci (adults: 74% (2019); larvae: 40% (2018), 84% (2019) and produced higher yields (13% (2018), 23% (2019)) than onions that were unsprayed, regardless of mulch type or onion cultivar. “Rossa di Milano” had relatively fewer adult and larval thrips populations compared with “Bradley” (21% (2018), 32% (2019)) and B5336AxB5351C. However, “Rossa di Milano” had the lowest marketable yield in both years. Reflective mulch reduced densities on certain dates in both years compared to white mulch, but the largest and most consistent reduction only occurred in 2019. Reflective mulch had no impact on bulb yield. While spinosad + neem oil reduced thrips numbers and increased yield alone, none of the treatment combinations were effective at suppressing populations of thrips. Future T. tabaci management in organic onions will require optimization of the available effective biopesticides.

Relevance. The most common and most mastered method of growing onions, used in the middle zone of the Russian Federation, as well as in the northern part of European countries, is the cultivation of turnip onions from onion. It is believed that this method provides 75% of the production of the entire onion harvest. Due to the sharp increase in the prices of energy carriers, fertilizers, pesticides and agricultural machinery, the production of sharp varieties of onions, grown in the crop, has become unprofitable, and marketable products have lost competitiveness due to high costs. Significant changes in the reduction of labor costs can be achieved by improving the technology and technical means for the production of onions, creating conditions for their work. The effectiveness of designs for sowing seeds of onions, onion sets and planting onions-uterus is determined by the uniform distribution of the bulbs by area of nutrition, depth and their embedding.Results. The material presented in the work is devoted to the analysis of designs and some results of studies of a complex of machines for the production of onions developed in the Penza GAU.

AlliumCepathe scientific name of an onion. After potato Onion is the second most essential vegetable in our India. And also onions are very famous in all around the world. In India, the productivity of onion is about 13 lakh tons every month, and in the world, the onion productivity ratio is about 19.40 million. There are about 100 types of onion throughout the world and basically, India produces 9 types of major onion. Onion is very rich in vitamin C (12%)content and vitamin B-6( 5%)content and also rich in minerals like iron(1%) and calcium(2%). In the last 10 years, Maharashtra( 4905.0 thousand tons) is the biggest onion producing state in India. But in 2019 onion prices overlap at Rs 10 kg from Rs 100 kg as demand loss will take place. A huge amount of wastage of onion takes place every year due to bad Monsoon, transport system and the amount of wastage is nearly 25% of the total production. In 10 years a remarkable increase in the production of onion in India and also an increase in the area about 768,000 ha to 1064,000 ha. Onion production has been several benefits like it reduces our cholesterol level, fights against inflammation, decreases triglycerides and it contains a high amount of antioxidants. The impact of onion production on the Indian economy, an increase of onion productivity, price drop, Government policies related to onion production also have been focused on in this review.

Full textAbstract:
Field experiments were conducted from 2008 through 2010 near Lyons, GA, to develop integrated weed management systems for organic Vidalia® sweet onion (Allium cepa) production. Treatments were a factorial arrangement of summer solarization, cultivation with a tine weeder, and a clove oil herbicide. Plots were solarized with clear plastic mulch during the summer fallow period before transplanting onion. Cultivation treatments were twice at 2-week intervals, four times at 2-week intervals, and a noncultivated control. Herbicide treatments were clove oil plus vinegar, clove oil plus an emulsified petroleum oil (EPO) insecticide used as an adjuvant, and a nontreated control. ‘Savannah Sweet’ onions were transplanted in early-December each year, with cultivation and herbicide applications events occurring the following January and February. Onions were harvested the following spring. In addition to yield measurement, a subsample of harvested onion was stored in a controlled atmospheric (CA) storage facility to evaluate treatment effects on diseases of stored onion. Summer fallow solarization did not control the cool-season weeds present in these trials. Cultivating transplanted onion with a tine weeder effectively managed cutleaf eveningprimrose (Oenothera laciniata) and swinecress (Coronopus didymus) and improved onion yields in 2 of 3 years. There was little difference in overall performance between two cultivations and four cultivations with the tine weeder. The 1 year of marginal weed control with the tine weeder was due to persistently wet soils during winter months that inhibited optimum performance of the implement. Clove oil, combined with vinegar or an EPO insecticide, provided marginal weed control and had no effect on onion yield. Diseases of stored onion were unaffected by any of the treatment combinations, although overall incidence of diseases of stored onion was higher in 2010 compared with other years. This corresponds with the 1 year of marginal weed control with the tine weeder, suggesting that the presence of weeds may be a factor related to disease incidence during storage.

The discussion focused on the effect of NPK fertilizer named Phonska on the growth rate of red onion, and the crops production. In this study, the method used is descriptive study lasted three months, from July 2011 to October 2011. The data collection techniques used in the preparation of this paper is a randomized block design (RBD ) and documentation . Based on the results, this study showed that the effect of NPK fertilizer Phonska on onion production are very significant. Phonska influence the number of tillers, because it meet the nutrient needs of plants so the crops able to produce well. For better results in the production of red onions we suggested that the cultivation of onion crop use NPK Phonska because it influence the development of onion growth. We recomended the relevant institutions to distribute NPK fertilizer and applying Phonska on onion crop growth to increase the production.

Single nucleotide polymorphisms (SNPs) were genotyped using a high-density array and DNAs from individual plants of important onion (Allium cepa L.) populations from major production regions and from the likely progenitor of onion, Allium vavilovii Popov et Vved. Genotypes at 1226 SNPs were used to estimate genetic relationships among these populations and revealed close associations among onions grown in Europe and those in North America, South America, and eastern Asia, supporting paths of introduction from Europe to the Americas and Asia. ‘Nasik Red’ is a population grown on the Indian subcontinent and was divergent from onions of European origin. Frequencies of SNPs among and within populations were used as a measure of informativeness, and 199 commonly polymorphic SNPs were identified distributed across the eight chromosomes of onion. These SNPs will be useful for estimations of relatedness among broader collections of onion populations, mapping of important phenotypes, fingerprinting of inbred lines and hybrids, and quality control of seed lots.

Full textAbstract:
Onions are one of the most important vegetable crops worldwide. However, their production faces many challenges. Genetic improvement is one mechanism to address those challenges. In this review, we discuss recent research pertaining to the diseases Fusarium basal rot and Iris yellow spot, the insect pest onion thrips, onion pungency, and dormancy. Recent research for screening onion bulbs for Fusarium basal rot resistance has resulted in improved screening techniques and germplasm exhibiting less disease when inoculated with the disease-causing pathogen. Improved screening methods have resulted in germplasm exhibiting fewer and less severe Iris yellow spot symptoms when onion thrips and conducive environmental conditions are present. Onion germplasm with less and differing compositions of epicuticular wax on their leaves have shown a nonpreference for thrips feeding and have the potential for developing thrips tolerant cultivars. Conventional breeding efforts and genetic manipulation of the genes producing alliinase and lachrymatory factor synthase has resulted in low pungency, tearless onions. In long-day onions, an annual generation time has been achieved by artificially breaking bulb dormancy early while ensuring proper vernalization has been completed. Genetic improvement of these and many other onion traits will continue and result in better production in the future.

Full textAbstract:
Weed control in organic onion production is often difficult and expensive, requiring numerous cultivations and extensive hand weeding. Onion safety and weed control with mustard seed meal (MSM) derived from Sinapis alba was evaluated in greenhouse and field trials. MSM applied at 110, 220, and 440 g m−2 severely injured onions and reduced onion stand by 25% or more when applied from planting to the one-leaf stage of onions in greenhouse trials. MSM derived from mustard cultivars ‘IdaGold’ and ‘AC Pennant’ reduced plant dry weight of redroot pigweed with an effective dose that provided 90% weed control (ED90) of 14.5 and 3.2 g m−2, respectively, in greenhouse trials, whereas the ED90 of MSM from a low-glucosinolate cultivar ‘00RN29D10’ was 128 g m−2, suggesting that glucosinolate content and ionic thiocyanate (SCN−) production contribute to phytotoxicity of MSM. In field trials, weed emergence, onion injury, and onion yield were recorded following single or three sequential applications of MSM from 1.1 to 4.5 MT ha−1 beginning at the two-leaf stage of onions in 2008, 2009, and 2010. By 8 wk after treatment (WAT), onion injury following MSM sequential applications was 10% or less in all 3 yr. Combined over 2008 and 2009, 48 and 68% fewer weeds emerged 3 WAT with MSM at 2.2 and 4.5 MT ha−1, respectively. In 2010, MSM at 2.2 and 4.5 MT ha−1 reduced the number of weeds emerged 4 WAT by 91 and 76%, respectively. MSM treatment did not significantly affect onion yield or size in 2008 and 2009, but in 2010 onion total yield was reduced by 29% by three sequential applications of MSM at 2.2 MT ha−1. MSM has potential to be used as a weed-suppressive amendment in organic production systems, but the risk of crop injury is substantial.

Full textAbstract:
In Russia, the major share of vegetable products is produced during the period of March to August. This is due to the inadequate volumes of vegetables fit for long-term storage, and the use of technologies of early production of vegetable cultures. Apart from the above, vegetable farming is highly dependent on imported seed stock. In view of the above, import phaseout and improvement of competitiveness of vegetable cultures in Russia should focus on the development of technologies of production of storable products, as well as on methods of early harvesting of vegetables (during the period of May to July). With regards to the production of bulb vegetables, this problem may be solved by expanding industrial cultivation of onions from set onions, as well as planting of both seeds and seedlings during the autumn season. In particular, techniques of production of set onion, bulb onion from seedlings, and of blackseed onion have poor scientific and methodological background. This deficiency results in a gap between domestic and international process and engineering aspects. This calls for the development and introduction of machines designed for production of onion from seedlings that would be in line with the modern level of development of farm machinery industry for vegetable production.

Onions were grown with different soil water potentials as irrigation criteria to determine the soil water potential at which optimum onion yield and quality occurs. Furrow irrigation treatments in 1992 and 1993 consisted of six soil water potential thresholds (-12.5 to -100 kPa). Soil water potential in the first foot of soil was measured by granular matrix sensors (Watermark Model 200SS, Irrometer Co., Riverside, CA) that had been previously calibrated to tensiometers on the same silt loam series. Both years, yield and market grade based on bulb size (more jumbo and colossal onions) increased with wetter treatments. In 1993, a relatively cool year, onion grade peaked at -37.5 kPa due to a significant increase in rot during storage following the wetter treatments. These results suggest the importance of using moisture criteria to schedule irrigations for onions.

Onion has become one of the popular horticulture commodities in Indonesia due to the crop having several benefits. Consequently, the demand for onions in Indonesia increases annually. In contrast, the supply of onion fluctuates because of unstable onion production. One of the factors that affect unstable onion production is soil fertility degradation. Therefore, the study aimed to analyze the effect of different doses of inorganic fertilizer compounds on the chemical properties of soil, plant growth and production. The field research was conducted in the experimental land of the Faculty of Agriculture, Brawijaya University, located in Jatimulyo Village, Lowokwaru District, Malang City. This study could not detect a significant difference in fertilization doses on onion plant growth but could increase the yield and tiller numbers. The highest values of tillers number, tuber fresh weight and tuber dry weight were observed for the treatment of 50% basal fertilizer + 150% compound inorganic fertilizer and the lowest production of biomass, tillers number, wet weight, and tuber dry weight was on treatment control.

In onions, sulfur-containing compounds and allinase enzymes are responsible for their lachrymatory effect and pungency. Flavanoid compounds in onions like kampeferol and quercitin show anti-inflammatory and antioxidant properties. Globally, India stands second in onion production, book keeping for 10 % of total production from 16 % of total area. As per FAO data (2012), China leads the world in production (20.5 million tonnes), followed by India (13.3 million tonnes). Maharashtra, Madhya Pradesh, Karnataka, Rajasthan, Bihar, Gujarat, Andhra Pradesh, Haryana, West Bengal, Gujarat, and Uttar Pradesh are the top onion-producing states in the country, contributing nearly 90% of the country’s overall onion production. Maharashtra stands first in production with 8,854.09 thousand tonnes with 38.09 percent share, followed by Madhya Pradesh (15.92 percent share) and Karnataka (12.85 percent share) (https://agriexchange.apeda.gov.in). Onion is a nutrient-sensitive crop and the nutrient requirement varies with cultivar, location, and season. Fertilizer recommendation for onion crop is 100-150 kg N, 40-80 kg P2 O5, and 0-125 kg K2 O per hectare (Source: NHB). Many studies have reported that 2.1 kg N, 0.75 kg P2 O5 , 2.2 K2 O, and 0.28 kg S per hectare of nutrients are removed by onion crop to produce a bulb yield of 1 ton (DOGR, 2015). Use of synthetic fertilizers alone causes leaching, increases toxicity, and degrades the soil environment. A Study by Kwaghe et al. (2017) have shown that nutrient uptake by the onion crop enhanced to 0.76, 43.82, and 2.42 kg/ha by the combination of both organic and inorganic fertilizers, thereby increasing the crop yield. Therefore, a rising need exists to provide an adequate and balanced nutrient application for attaining good crop yield and quality without affecting soil fertility status. This INM based approach for nutrient management has a positive impact on plant growth, agricultural sustainability, and fertility of soil. Hence to enhance soil fertility and to improve the nutrient uptake, the concept of Integrated Nutrient Management (INM) could be adopted.

Onions are a significant source of revenue and food security for households. Despite their importance in human nutrition, economic benefit, and area coverage, in Ethiopia, onion productivity is significantly lower than it should be. The purpose of this study is to address this gap by examining efficiency variations and determining the variables that affect onion farmers’ levels of efficiency in the North Gondar Zone of Ethiopia. The sources of data were both primary and secondary. 205 onion farmers from the Gondar Zuria, Takusa, and Dembia districts were chosen using simple random sampling proportional to sample size. Semi-structured interviews were used to gather primary data from these participants. A Cobb-Douglass production function, a single-stage stochastic frontier model, and descriptive statistics were used to investigate the technical efficiency of onion production at the farm level. The mean technical efficiency of an irrigated onion was 53%, according to the maximum likelihood estimates of the stochastic frontier analysis. By enhancing agricultural methods using current technology, it is possible to raise the average production efficiency of irrigated onions. The stochastic frontier model’s maximum likelihood estimates revealed that plot size, Di Ammonium Phosphate, and oxen have a significant effect on onion output; education, livestock holding, experience, and frequency of watering have a positive and significant effect on technical efficiency, whereas family size and marketing training have a negative and significant effect on technical efficiency. Therefore, the government or any relevant bodies should deliver continual scheduled training and an integrated adult education at the existing farmers’ training center; modern livestock production techniques; further groundwater resources and proper watering technologies should be used since currently farmers use an inefficient irrigation system, specifically furrow irrigation.

The main goal to be achieved is to be able to make an onion slicing machine so that it can answer the problem if the onion slicing is carried out in a larger capacity. The onion slicing machine is made to support the increase in the production of shallot slices, which are ready to be fried for the production of scallion onions in household industries. In a small scale, the work can be done manually with a knife or other simple cutting tool. Problems will arise if large quantities of sliced or cut production are available. In order to facilitate the community in processing shallots and learn about the problems, namely how to produce a shallot slicing machine with uniform slices results using different slope angles on the knife. the working principle of this machine is the Onion which has been peeled dry skin inserted into the funnel then the plate on the back of which has a knife, will rotate because it is driven by an electric motor. As a result of the rotation the onion will be sliced and the slice will fall down, and below it a container will be used as a cross section of the onion which has been finished sliced as a result

Full textAbstract:
Onion production is reliant on synthetic chemical inputs such as fertilizer and pesticides to ensure its profitability. In the Great Lakes region (USA), onion thrips (Thrips tabaci) and a complex of bacterial pathogens that cause bulb rot disease threaten the sustainability of onion production. The potential exists for reducing T. tabaci infestations and bulb rot disease incidence in onions by decreasing the amounts of fertilizer applied at planting and the insecticide applied to foliage during the season. In a three-year study that included 20 New York commercial onion fields, the impact of synthetic fertilizer (no fertilizer, half rate, and full rate) and insecticide use (action threshold-based application program and weekly application program) on T. tabaci populations and bulb rot disease incidence was examined. Results indicated that the amount of fertilizer applied to an onion at planting had no impact on T. tabaci population levels, bulb rot disease incidence, or onion bulb size and yield. In contrast, insecticide use had the greatest impact on reducing T. tabaci densities. Both the action threshold-based program and weekly spray program reduced T. tabaci infestation levels below the economic injury level, but the action threshold program averaged 2.3 fewer applications per season. The insecticide program had no effect on bulb rot incidence, bulb size, or yield. We conclude that synthetic fertilizer and insecticide inputs can be reduced substantially without compromising onion bulb yields, and this should lead to greater profits and a reduction of chemicals in the environment.

Today's technological developments are growing rapidly, but there are still jobs that are done manually and semi-manually. This paper aims to develop a control system to coordinate the work of tools using an electric motor, which is very helpful in the process of cutting onions in large quantities and is more efficient in spending production costs because the tool designed is an automatic onion cutter. This research method begins with the collection of materials and data related to onion cutters, production of onion cutters, and testing of onion cutters. The measurement results of the tool show that every component in the automatic onion cutter works well and optimally; the measurement process is carried out properly and thoroughly. This optimal work result is supported by Arduino Uno. The Arduino Uno microcontroller acts as a tool controller. In the main system, the onion cutter is controlled by the Arduino Uno with the Arduino programming language. This automatic onion cutting system will work when the onion you want to cut has been inserted into a cross-section that has been equipped with an ultrasonic sensor, and then the onion cutting process is carried out. Compared with the manual method, the cutting time is almost the same. It's just that the advantages of slicing with this tool, the resulting slices are relatively more uniform. Besides that, another advantage is that it doesn't hurt the eyes of the onion slicer. So that this tool can be used by small entrepreneurs and onion farmers to increase productivity and the community's economy.

Full textAbstract:
Long growing seasons, relatively shallow root system, coarse textured soils, and variability of the subtropical environmental conditions of the southeastern U.S. create challenges for nitrogen (N) fertilizer management of short-day onions. The objectives of this study were: (i) to evaluate the impact of fertilizer N rates on the yield and bulb quality of three short-day onion cultivars grown under the subtropical conditions of the southeastern U.S., and (ii) to assess the impact of fertilizer N rate for short-day onions on consumers’ preference. Field experiments were conducted in 2019 and 2020 at the Vidalia Onion and Vegetable Research Center at the University of Georgia located in Lyons, GA, in which a two factorial experimental design of five fertilizer N rates (84, 101, 117, 134, and 151 kg of N ha−1) and three short-day onion cultivars (Sweet Agent, Vidora, and Quick Start) was evaluated in a randomized complete block design. During both growing seasons, rainfall events directly impacted soil mineral N content. While soil mineral N availability increased with fertilizer N application, there was no significant difference among fertilizer N rate treatments due to rainfall distribution in both years studied, except at bulb initiation when the application of 117 kg of N ha−1 sustained soil mineral N availability that maximized with the application of 128 kg of N ha−1. Onion total yield averaged 37,365 kg ha−1 in 2019 and 34,699 kg ha−1 in 2020. In general, colossal, jumbo, and medium-sized onions represented 7%, 76%, and 17% of total yield, respectively. Jumbo-sized onions are of most interest to growers due to their high value, and the yield of jumbo-sized onions was maximized with 158 kg of N ha−1 in 2019 and with 138 kg of N ha−1 in 2020. Bulb bacterial rots were not impacted by fertilizer N rate treatments. Contrarily, bulb gallic acid (GAE) linearly increased and pyruvic acid quadratically increased with the application of fertilizer N rate. Ultimately, a taste panel indicated that sensory characteristics were also not affected by different rates. Overall, a fertilizer N rate application of 117 to 134 kg of N ha−1 could sustain soil mineral N availability without impacting yield; however, an investigation on the timing of application should be conducted to determine a fertilizer N strategy that will promote optimum yield, bulb quality, flavor, and consumer acceptability.

One of the main directions of onion crops breeding in the world is heterosis breeding. Heterosis hybrids occupy the main place in the commodity production of onions in the Netherlands, USA, Japan and other countries. In State Register for Selection Achievements Admitted for Usage (National List) of the Russian Federation, admitted to use in 2018, made 378 cultivar of onions, including 188 (49.7%) – F1 hybrids, of which 140 – foreign breeding. A common way to create heterosis hybrids F1 onions is the use of lines with cytoplasmic male sterility (CMS) as one of the parent forms. The article presents the results of multi-year research of the laboratory of breeding and seed production of onion cultures (VNIISSOK, now FSBSI FSVC) to assess and highlight the lines of CMS onions with high combinational ability, the creation of heterosis hybrids on their basis. In 2002-2005, 229 cultivar of onion were studied to identify plants with pollen sterility and maintainer. 515 plants with CMS were isolated. In the subsequent years (2006-2010) was established 1588 maternal lines (S msms) and the fathers of maintainer (N msms). To obtain F1 hybrids with the maximum level of heterosis, the combined ability of lines and pollinators was evaluated by topcross and diallel crosses. The best lines for the complex of economically useful features with high combinational ability were included in various combinations of crosses with inbred lines in order to select high-performance hybrid combinations and to create F1 hybrids. 547 combinations of crosses of sterile lines with inbred paternal lines were carried out, on the basis of which 408 F1 hybrids were created. After testing and evaluation of them in the hybrid and breeding nurseries allocated 23. According to the results of the competitive test samples were identified, which under the names of Logran F1, Zarnitsa F1 and Solnyshko F1 transferred to the state variety test.

Instructors often present Mendelian genetics and molecular biology separately. As a result, students often fail to connect the two topics in a tangible manner. We have adopted a simple experiment to help link these two important topics in a basic biology course, using red and white onions bought from a local grocery store. A lack of red coloration in white onions is a result of one or more mutations in the color production pathway. This mutation can be seen by the use of polymerase chain reaction (PCR) followed by gel electrophoresis. An absence of an amplified PCR product for one of the genes necessary for color production is associated with a lack of color production – an obvious trait in white onion. The students are able to “see” the difference at the DNA level between the red and white onion.

Botrytis leaf blight (BLB) of onion (Allium cepa) is caused by Botrytis squamosa. The disease has been reported on onion crops in several of the onion production areas of the world including North and South America, Europe, Asia, and Australia, although it is not a problem in arid production regions such as the western United States. In eastern Canada, the disease is generally present every year and is especially severe on cultivars of yellow globe onion. The pathogen biology and disease epidemiology have been intensively researched. Over the last few decades, in the organic soil area of Quebec, extensive research effort has been devoted to the development and evaluation of predictive models and disease management strategies. There has been an active integrated pest management program for onions since the early 1980s, and scouting for disease has played a major role in disease management. In this article, the story of BLB management in eastern Canada over a period of two decades is summarized.

AbstractA spatial, intertemporal equilibrium model of the North American dry onion economy is constructed to analyze the impact of liberalized U.S.-Mexico trade. In a free-trade environment, exports of Mexican onions to the U.S. are projected to increase about 50%, while Mexico's share of the U.S. market increases from 8.7 to 12.8%. Farm-level prices in the U.S. are projected to decline 8.9%, while production declines 2.4%. The effect of free trade on U.S. producers is disproportional across regions. Northwest storage onion producers experience the greatest decline in production; however, analysis suggests that improved storage methods may offset a portion of the unfavorable impacts of liberalized trade on these producers. In spite of the unfavorable impact of free trade on U.S. dry onion producers, the industry would not be economically devastated.

Metam sodium has been evaluated on onions in Georgia since the mid-1980s for control of various soil pathogens in the production of transplants. Observations also indicated excellent weed control activity. Further work showed significant growth response of transplants, 90% or better weed control, and efficacy of Phoma terrestris, Fusarium, and Pythium. Results were better in comparison studies than found with methyl bromide, chloropicrin, and other fumigation combinations. This led to use of the product in field production of dry bulb onions. Seven years of studies revealed an average yield increase of 190 bushels per acre over the control, even where Phoma terrestris levels were minimal. Today, almost all transplant production includes the use of metam sodium and field use is beginning to be used by growers. With limited crop rotation being practiced in the Vidalia onion belt, metam sodium will continue to play a major role in controlling the ever-increasing levels of Phoma terrestris and maintaining profitability in onion production in Georgia.

According to the Pakistan Bureau of Statistics, Pakistan is amongst the top ten onion-producing countries in the world. Though in Pakistan, most of the districts of Khyber Pakhtunkhwa produce onions, Malakand division lonely contributes 60% of the total onion production of the country. In onion farming, bolting is an insidious phenomenon that occurs in onion plants due to fluctuations in environmental factors such as temperature, humidity, and light intensity. Due to bolting, the flowering stem of an onion plant is produced before the crop is harvested, resulting in a poor-quality harvest and yield. Therefore, from a farmer’s perspective, it is highly desirable to monitor and control the environmental factors to avoid bolting. In this paper, we propose and design a new prototype, namely, a smart farming monitoring system (SFMS) for bolting reduction, which is based on the generic three-layered IoT architecture. By using IoT (Internet of things) technology and careful remote monitoring, a more favorable environment can be provided to reduce and avoid onion bolting. To analyze the efficacy and performance of the proposed SFMS, a real test-bed implementation was carried out. The SFMS prototype was installed both in the open and in a greenhouse environment to monitor onion crops. Based on the data received via sensors, the percentage of onion bolting was recorded as 16.7% in the open environment while 3% in the closed environment. In the closed environment, optimal temperature, humidity, and light intensity were provided to the onion crops using the SFMS. For this reason, the percentage of onion bolting was reduced from 16.7% to 3%, consequently yielding better onion production. Moreover, the SFMS is a low-cost, easy-to-install solution that is developed with locally available hardware and resources, and we believe that this new solution can transform conventional onion farming into a more productive and convenient smart farming in the region.

This study investigates onion producers’ technical efficiency level in Kebbi State. Purposive and simple random sampling procedures were adopted in selecting 210 onion producers using structured questionnaire from seven local government areas in the state. Descriptive statistics, gross margin and stochastic frontier production models were employed in describing and analyzing the data. The results showed that producers generated an average gross revenue and gross margin of ₦1,085,692.51 and ₦700,388.33 at farm-gate price, respectively. The coefficients of farm size (0.6779), labour (0.1700) and seed (0.01011) were significantly positive in influencing the onion output, while level of education and household size significantly increased technical efficiency of producers. The technical efficiency of the pooled sample ranges from 0.13 to 0.95 and the mean technical efficiency was 0.78. Production constraints recorded were; high cost of input, pest and disease attack, poor pricing and inadequate government support. In conclusion, onion is a viable agribusiness enterprise for wealth generation and reliable means of small producers’ livelihood and lucrative business for large scale producers. The study recommends the need to identify sustainable interventions through government/nongovernmental support policies to improve input supply system, encourage adult education vide extension service and strengthening linkages among onion producers.

Dry bulb onion (Allium cepa) leaves may not dry down normally and bulbs may not attain dormancy during adverse growing seasons. An effective method of artificial leaf desiccation is needed to complement mechanical harvesting and onion conditioning for storage. Desiccants were tested in 1993, 1994, 1995, 2001, 2002, 2003 on onion leaves prior to harvest, and bulb quality was evaluated after 5 months or more of storage. Carfentrazone, diquat, and paraquat desiccated onion foliage well but increased bulb rot and reduced the percentage of marketable bulbs after storage. Bromoxynil and endothall desiccated onion foliage significantly without inducing rot or reducing the percentage of marketable bulbs. Copper sulfate and pelargonic acid increased desiccation of onion foliage but were not sufficiently effective for field use. Neither reduced the percentage of marketable bulbs. If bromoxynil or endothall were labelled for onion desiccation, they could be applied 10-14 days before harvest to enhance natural leaf senescence and facilitate mechanical harvest.

Abstract Modern agricultural technologies of onion cultivation should follow high requirements for their planting. The construction of the onion planter coulter determines the quality of planting. The authors designed the drill coulter for sowing onions, which qualitatively prepares the planting furrow by leveling and compacting the surface of the furrow bottom. The use of skid coulters allows to hold them on a single row, that, including protection against damage during leveling and compaction of the furrow bottom in a single row unit, reduces the metal consumption of the coulter and increases its compactness. When determining the parameters of the coulter, considering the condition of stability of its movement when planting onion row units, a theoretical substantiation of the traction resistance was carried out. When determining the parameters of the coulter, taking into account the conditions of stability of its movement when planting the onion-sowing, a theoretical justification of the traction resistance was performed, with the possibility of regulating the pressure force of the coulter on the soil with a row spacing of 0.20 m, for the range of the speed of the sowing 3.6 …5.4 km / h, the depth of the coulter 30…50 mm when planting the onion-sowing. The design of the coulter and its theoretical justification are proposed, which makes it possible to reduce the traction resistance, as a result of which the emission of exhaust gases into the atmosphere is reduced. As a result of the uniform distribution of nutrition over the area and the uniformity of onion shoots, weeds are decline, which reduces the use of herbicides, and therefore increases the environmental friendliness of the products produced.

A total of 200 managers and caretakers of bunching onion farms in the study area were identified through purposive sampling. Questionnaire with a combination of close and open-ended questions was used in the interview. Chi- Square was used for testing the correlation and association.Results show that majority of the respondents, who have an average age of 51 years, indicate that bunching onion production is their primary source of income and they have been in farming for no less than 15 years. Less than 50% of the respondents have an average farm size of .5 hectare and majority of them are tenants. Most of the producers were not able to go beyond secondary education and majority, and has no affiliation to any farmers organization. Also, majority of the respondents have not attended any seminar on bunching onion production.Apart from the demographic profile, the respondents production and operation management of their bunching onion farms were documented. Marketing management, which includes pricing and selling, was recorded. Results reveal that both growers and viajeros are the ones who decide on the price of bunching onions.Based on the data, an average income of Php 436,450.00 can be earned from .5 hectare in one cropping. Return on Sales (ROS) of 90.93% shows that every peso earned from the sale of the product there is a corresponding Php 0.91 centavos net return. Return on Investment (ROI) of 10.02% shows that for every Php 1.00 invested there is a corresponding Php 0.10 centavos net return.The study revealed that the level of yield and profit per hectare per cycle isinfluenced by the educational attainment, household size, and farm size, but are not influenced by age of the respondents. The major problems of the bunching onion farmers are the high price of seeds, insufficient capital, insect pests and diseases. Data revealed that growing bunching onions is profitable and a considerable income can be obtained in 2 to 3 months. Conduct of similar studies on bunching onion production in other towns is recommended to compare the profitability and the practices. Encouraging the farmers to practice companion cropping or any cropping system with higher biodiversity on order to enhance productivity per unit area is likewise recommended. Further, the bunching onion farmers must be organized and be extended with applicable trainings and assistance by concerned agencies and entities in order to improve their status and productivity.

Experiments determined the effectiveness of the bipyridinium herbicides paraquat and diquat and of the diphenyl ether herbicide lactofen to desiccate onion (Allium cepa L.) shoots without affecting bulb quality and storage life. Paraquat, applied once, desiccated 80% of onion shoots within 3 days. Diquat desiccated ≈ 60% of onion shoots within 10 days of treatment. Lactofen caused slight necrosis but did not adequately desiccate onion shoots. Diquat and paraquat reduced sprouting of `Red Wethersfield' more than of `White Portugal'. Chemical names used: 6,7-dihydrodipyrido[l,2 2',1'-c] pyrazinediium ion (diquat); (±)2-ethoxy-l-methyl-2-oxoethy1 5-[2chloro-4-(trifluoromethyl)phenoxyl] -2-nitrobenzoate (lactofen); 1,1'-dimethyl-4,4'-bipyridinium ion (paraquat).

Extending the season can provide opportunities for vegetable producers. Bunching onion, or scallions (Allium fistulosum L.), is a crop that can be a candidate for protected production used to extend the growing season. The cvs. Evergreen Hardy White (white), Deep Purple (red), and Nabechan F1 (white) were sown at monthly intervals from Sept. 2010 to Aug. 2011 in containers under greenhouse and hoop house conditions at Lane, OK. Days to harvest and yield variables were determined. Crop failure occurred in a greenhouse for all plants sown in July, for ‘Deep Purple’ sown in August, and for those sown in a hoop house in February and March and May through August, days to harvest was generally less for plants sown in the greenhouse, and for ‘Deep Purple’, but all plants took longer to reach marketable size than is indicated for field production. Yields for plants grown in the greenhouse were higher than for those grown in the hoop house. Greenhouse production provides more flexibility and protection from environmental conditions so that bunching onions can be grown for extended season production. However, environmental controls under greenhouse conditions need to be refined to reduce length of growing season while maintaining, or improving, yields of optimally sized plants. Programs to improve nutrition in school systems and introduction of “Farm to School” and “extended season” initiatives present opportunities for production of some vegetables including bunching onion, or scallions. “Farm to School” programs allow the use of fresh, locally grown foods to be incorporated into school menus. Bunching onions can be used fresh or prepared items. Use of protected culture in greenhouses and hoop houses may allow for extended season production of these onions so that they can be used during non-typical growing periods especially, when locally produced field-grown crops are not available.

This study aims to determine the changes in, and bioaccessibility of, polyphenols and organosulfur compounds (OSCs) during the simulated gastrointestinal digestion of black onion, a novel product derived from fresh onion by a combination of heat and humidity treatment, and to compare it with its fresh counterpart. Fresh and black onions were subjected to in-vitro gastrointestinal digestion, and their polyphenol and OSC profiles were determined by ultra-high-performance liquid chromatography coupled with high-resolution mass spectrometry (UHPLC-HRMS). Although to a lesser extent than in the fresh onion, the phenolic compounds in the black variety remained stable during the digestion process, presenting a higher bioaccessibility index (BI) with recovery corresponding to 41.1%, compared with that of fresh onion (23.5%). As for OSCs, apart from being more stable after the digestion process, with a BI of 83%, significantly higher quantities (21 times higher) were found in black onion than in fresh onion, suggesting that the black onion production process has a positive effect on the OSC content. Gallic acid, quercetin, isorhamnetin, and ɣ-glutamyl-S-(1-propenyl)-L-cysteine sulfoxide were the most bioaccessible compounds in fresh onion, while isorhamnetin, quercetin-diglucoside, ɣ-glutamyl-S-methyl-L-cysteine sulfoxide and methionine sulfoxide were found in black onion. These results indicate that OSCs and polyphenols are more bioaccessible in black onion than in fresh onion, indicating a positive effect of the processing treatment.

Onion is an inevitable item in all Indian kitchens. As onion is an important and obligatory item of consumption basket, fl uctuation in its prices will have great impact on food consumption pattern of the Indian consumers. The present study was conducted to identify the major constraints in the production and marketing of onion in Haryana. Ambala and Mewat districts were selected purposively based on the largest area under onion in the state. In total 200 onion growers were randomly selected for collecting the required information. Garrett’s ranking technique was used to analyze the results. The study revealed that the high labour cost was the major constraint in the production of onion in Ambala district followed by high incidence of pest and disease and viability of seed. As regards to major constraints reported by the respondents during the marketing of onion were frequent price fl uctuation, non-availability of storage facility and lack of awareness of BBY/government procurement (NAFED). Regarding the production of onion in Mewat district, major constraints observed were poor quality and inadequate underground water, high cost of onion seed, non availability of quality seed, etc. The study further found that the major constraints observed during the marketing of onion in Mewat district were distance market, non-availability of storage facility, high transportation cost. Adequate storage facility needs to be created enabling the producers to spread the sale throughout the year. Eff orts may be made to supply quality seeds and also to safeguard the producers against the low prices during the peak season.

Relevance. Onion is a valuable food crop, which is due to its chemical composition, taste and medicinal qualities. As part of the strategy to ensure food security and independence of Russia in the agricultural sector, it is necessary to increase the production of vegetable products, including onions, and for this it is necessary to increase the production of domestic seeds. Seed production is an important branch of agriculture, which consists in the planned reproduction of zoned varieties. Unlike commodity production, it is a more labor-intensive industry and requires regular improvement of existing technologies that take into account the specifics of new varieties and hybrids.Materials and methods. The object is onion (Allium сера L.). Research material: new varieties of spring onion Primo and Ampex of selection of FSBSI FSVC. The studies were conducted in 2018-2020 on the basis of the North Caucasus branch of the FSBSI FSVC. Laboratory and field experiments were carried out according to generally accepted methods. The area of the accounting plot is 5m2 , the repetition is 4-fold, with a randomized arrangement of options.Results and discussions. Different planting dates of uterine bulbs, their diameter, standing density, planting depth, significantly affected the qualitative and quantitative indicators of seed productivity of onion plants of Primo and Ampex varieties. The results obtained made it possible to modify and optimize individual elements of varietal technologies of onion seed production. To create the best conditions for the growth and development of seed plants of Ampex and Primo varieties and to obtain high yields of high-quality seeds in the conditions of the foothill zone of the North Caucasus, it is recommended to: use queen bulbs of 8 cm in size, organize the planting of queen bulbs in the first decade of November, use a scheme for planting queen onions: 75x10 cm, use a planting depth of 15 cm. With this technology, the productivity of plant seeds reaches 6-8 g in the Ampex variety and 5-7 g in the Primo variety, and the yield of conditioned seeds is 520-580 kg/ha and 450-600 kg/ha, respectively.

The present study attempted to estimate the profitability, domestic resource cost (DRC) and problems and prospects of onion production in the study areas. Both primary and secondary data were used in this study. Sample survey was carried out in two selected areas under Kushtia and Jhenaidah districts. A total of 110 onion producers were selected randomly of which 70 producers were from Kushtia and the remaining 40 producers were from Jhenaidah. The study showed that, on an average, total costs of onion production per hectare were about Tk. 150,097 and 116,831 in Kushtia and Jhenaidah district, respectively. The benefit cost ratios (BCR) of onion production were 2.02 and 1.83 in Kushtia and Jhenaidah district, respectively. The results of profitability and BCR show that onion is a profitable crop in Bangladesh. The domestic resource costs (DRC) were 0.47 in Kushtia and 0.52 in Jhenaidah, which indicate that Bangladesh has comparative advantage in onion production. The coefficients of the production function show that farm area, irrigation, pesticides, seeds, chemical fertilizers (TSP) and labor were statistically significant affecting factors of onion production and it shows constant returns to scale. The onion producers faced some production, technological and marketing related problems in the study areas. The government should therefore, take necessary policies for further development of onion production in Bangladesh.The Agriculturists 2017; 15(2) 66-78

In Pakistan, onion is one of the most grown commercial crops in the various parts of the country. The study was carried out through a primary data collection from various stakeholders to examine the status of onion production in Balochistan province. The average per acre cost of production, productivity, profitability, input output ratio were analyzed. Furthermore, find out the issues and constraints faced by onion growers and recommend policy guidelines for sustainable onion production and marketing in the study area. Costs have been broken down in a variable, fixed and opportunity costs (depreciation and opportunity) costs for production factors that are owned by the onion growers. While the variable cost was high from other costs, among them seed rate cost was high in the variable cost and in the lowest costs was recorded in chemical weedicide from other variable costs and fixed cost was nil due to relief from Balochistan government, whereas total cost of production and net income was Rs.82737 and Rs.75665 per acre respectively found in the study area. Majority 67% seed dealers were reported that due to high ratio of population, more consumable, good seed quality, more benefit, short duration of time and more production of onion as the principal reason for increase seed suppliers over the past 5 years. Onion farmers must follow best methods in management and strive to adopt scientific guidance from local and other available sources, for example research stations, progressive producers and extension workers.

Scombrotoxin fish poisoning (SFP), also known as histamine (Hst) poisoning, has been associated with consumption of scombroid-type fish, including tuna and tuna fish products. Preparation of commercial tuna salad contaminated with Hst-producing bacteria (HPB), combined with time-temperature abuse, can present a food safety hazard. A potential source of HPB is raw ingredients, such as celery and onions. The objectives of this study were to determine whether raw ingredients can be a source of HPB and to ascertain the effects of storage time (up to 4 days or 4 weeks) and temperature (4, 10, 18, 25, 30°C) on growth and Hst production by high-HPB (>1,000 ppm of Hst) in tuna salad preparations. Pantoea-Erwinia, Erwinia persicinus, Erwinia spp., and Enterobacter pyrinus isolated from celery in this study were used to inoculate tuna salad and tuna salad with celery or onion. HPB numbers were 0.7 to 4.3 log most probable number per g higher in the presence of celery or onion versus plain tuna salad (3:1 tuna:mayonnaise). E. pyrinus–inoculated plain tuna salad and tuna salad with celery and onion had >500 ppm of Hst after 2 days at 30°C and 4 days at 25°C. E. pyrinus–inoculated salad with celery and onion had >500 ppm of Hst after 4 days at 18°C and 2 weeks at 10°C. Raw celery can introduce HPB into tuna salad, which can cause SFP if the product is time-temperature abused. Tuna salad products must be refrigerated at ≤4°C to prevent growth and Hst production by the HPB used in this study, to protect consumers from potential SFP.
