Abstract:

Liquid fertilizers in dry season vegetable production are applied using different cropping patterns with little or no empirical evidence on which pattern is the most profitable. This study, therefore, investigated the effect of cropping patterns on the profitability of liquid fertilizer usage in dry season vegetable production. Specifically, the study identified the various vegetable enterprises, assessed the inputs and outputs of the different vegetable enterprises and estimated the profitability of the vegetable enterprises. A multi-stage random sampling procedure was used to select 309 farmers in the Southern Guinea Savannah zone. Pretested and structured interview schedules were used for data collection. Descriptive statistics and partial budgeting techniques were used for data analysis. Twelve different vegetable enterprises were identified in the study. Sixty percent of users of liquid fertilizer cultivated only fruit vegetables such as okra and peppers. The usage of the combination of both liquid and non-liquid fertilizers in mixed vegetable production yielded the highest quantity of output of about 1374kg/ha. However, usage of sole liquid fertilizer on exotic vegetables gave the highest profitability of 323 percent on the rate of return to capital investment. The study has concluded that the use of liquid fertilizer increases profitability and therefore recommends the formulation and implementation of policies that will encourage liquid fertilizer usage among the farmers.

Abstract:

The Kalimbu market is one of the traditional markets in South Sulawesi with a very high buying and selling activity. The organic waste that is mostly generated from the activities at the Kalimbu Market is leftover vegetables and fruit. Vegetable and fruit waste provides a big advantage if it is managed properly, which is converted into liquid organic fertilizer through a fermentation process. The liquid organic fertilizers produced can help farmers overcome the high price of synthetic fertilizers and save the earth from pollution. The method used to determine the effect of types of organic waste (vegetable waste and fruit waste) on the physical and chemical quality of solid and liquid organic fertilizers used a randomized block design. Whereas the application of solid and liquid organic fertilizers to the production and nutritional content of potato plants used a treatment consisting of P0: basic fertilizer + without liquid organic fertilizer and P1: basic fertilizer + liquid organic fertilizer. The results of research on the manufacture of liquid organic fertilizer from Kalimbu market waste with vegetable and fruit samples also showed that the two samples required different storage times for composting. Plants treated with liquid organic fertilizer from the Kalimbu market waste have better stem growth, leaf number, and stem number.Keywords: Waste, organic, fermentation, hydroponic

Abstract:

Nigeria is an agricultural country, most of the vegetable needs of its people being provided by small farmers who seldom use high-input technology. Over the last 20 years, there has been an encouraging upward trend in inorganic fertilizer consumption, but it is very difficult to estimate how much of this chemical fertilizer is used for vegetable production. There is a need for information which could be used to monitor national trends in fertilizer use on vegetables so that the government can predict future needs and advise manufacturing industry and farmers accordingly. Although increases in the yield and mineral content of vegetables through the use of chemical fertilizers have been recorded, several problems still preclude their use. Possible ways to overcome the problem and benefit vegetable growers are discussed.

Abstract:

Five fertilizer treatments, three of which included swine effluent alone or in combination with commercial fertilizers, were evaluated for plasticulture production of vegetables. Effluent and/or soluble fertilizers were delivered through drip irrigation tubing to their respective treatments. Four experiments were conducted at two locations: 1) spring tomatoes followed by pumpkin at Verona, Miss., 2) spring tomatoes followed by zucchini at Pontotoc, Miss., 3) fall tomato at Verona, and 4) fall tomato at Pontotoc. In all four experiments, representing six crops, yields from treatments receiving swine effluent were equal to or greater than yields from treatments receiving preplant fertilizers and/or commercially available soluble fertilizers. There were also no significant differences among treatments in relative number of marketable fruit. Leaf tissue analysis of the tomato crops showed no significant differences among treatments in N content. For some experiments, there were significant differences for other elements. These results showed that swine effluent was an effective nutrient source for plasticulture production of vegetable crops when compared to preplant and soluble fertilizers. These results also showed that the alkaline pH (about 7.8) and high level of ammonium nitrogen of swine effluent (>95 % of N content) did not adversely affect vegetable yield or marketability.

Abstract:

A segment of the greenhouse crop market would like to obtain vegetables and herbs that are certified organic. The technology for the use of biological controls for insects and diseases is well-developed and a significant part of greenhouse vegetable production. Organic fertilizers, however, have not been well-utilized in organic greenhouse vegetable production. Common organic fertilizers were analyzed for the levels of nutrients when mixed with water for use in greenhouse fertigation. Products derived from algae-Algamin (liquid) and Ohrstrom's Garden Maxicrop (powder), Bat Guano, and products derived from fish waste-GreenAll Fish Emulsion (liquid) and Mermaid's Fish Powder, demonstrated nutrient levels comparable to typical water-soluble fertilizers used for greenhouse plant production. Although the organic fertilizers could not be used as a concentrate for injector systems, readings from a conductivity meter were directly related to nitrate nitrogen levels and could be used for fertilizer management in the capillary mat subirrigation system used for plant production.

Abstract:

Purpose This paper aims to investigate the contents of heavy metals Cd, Cr, Ni, Cu, Pb and Zn in the soil of vegetable production bases in the Yongnian County of Hebei Province by random sampling. Design/methodology/approach The environmental quality conditions of these heavy metals were evaluated by both the single quality index and comprehensive quality index methods. Findings It was concluded that the average heavy metal contents in the soil of protected vegetable fields in the Yongnian County are all under the limit values prescribed by the environmental quality evaluation standard for farmland of greenhouse vegetables production (2007), so the soil’s environmental quality is classified as first class regarding cleanliness. It is fit for the plantation of non-polluted vegetables. It is shown that there is a cumulative trend of heavy metal contents in the soil with age after analysis of a correlation coefficient between heavy metal contents and age in Yongnian’s protected fields and excessive application of fertilizers or organic fertilizers, which is the main factor leading to an increase in heavy metal contents in the soil. Originality/value It is suggested that the amount of fertilizer should be properly reduced to prevent the soil’s environmental deterioration, the vegetable planting structure should be improved and the vegetables grown in areas with weaker accumulation of heavy metals should be cultivated.

Abstract:

Different types of pesticides and chemical fertilizers are in use in Nepal which is harmful for human health. These chemical fertilizers and pesticides are beyond the limitation and restriction. However, scientific study is very limited in Nepal. So, this study aims to assess the situation of use and protection system of pesticides users. This study is based on field level data of Godawari area of Lalitpur district. In Godawari area, Urea and DAP are mostly used for cereal crops and potash is mostly for vegetables. Pesticides and fertilizers are mostly used in vegetable farming but protection system during the use of pesticides and fertilizer is not satisfactory. So, these chemicals have been negatively affecting on the health of the local farmers.

Abstract:

TRAINING AND MENTORING OF ORGANIC VEGETABLE CULTIVATION IN BAROS VILLAGE, SERANG REGENCY. The increasing number of people and public awareness about the health of the growing demand for organic vegetables is also increasing. This is one of the business opportunities in the field of organic agriculture, especially organic vegetable cultivation. The economic analysis of organic vegetable cultivation shows that organic vegetable cultivation is profitable, so it can be used as an effort to increase people's income. Organic vegetables are vegetables that are processed by environmentally friendly process, using organic materials from agricultural and livestock waste, without using synthetic chemical fertilizers, and synthetic pesticides. Baros Village, Baros District, Serang District is an agricultural area suitable for organic vegetable cultivation, the availability of land for agriculture, good irrigation, organic fertilizer source widely available, and close to the capital of Banten province. Organic vegetable cultivation uses organic ingredients from agricultural and livestock waste that are around the site. Selection of vegetable seeds is done by selecting seeds that are superior and needed by the community. Soil processing is done by plowing the soil, followed by basic fertilization. Organic vegetable preservation is done with advanced organic fertilization, weeding, irrigation, and vegetable pesticide administration. The harvesting process is done by selecting good organic vegetables, washing, and packing vegetables. The most important aspect of community service programs is the potential for sustainability. The sustainability of the Organic Vegetable Cultivation program is able to support the economy and public health.

Abstract:

Field experiment was conducted at Research Farm of Kano University of Science and Technology, Wudil, to determine the effects of organic fertilizer on the nutritional status of Hibiscus sabdariffa (Roselle). The results obtained indicated the manure fertilizer to be higher in protein (20.910%) and crude fiber contents (12.047%), Zn (30.689mg/kg) and Cu (18.571mg/kg) concentrations, no Pb was detected at all. However, the difference that exists amongst the fertilizers (T2 and T3) and poultry manure (T1) was found to be insignificant in so many parameters. Therefore, the study work with regard to the findings revealed that organic fertilizer (poultry manure) had the potential over the inorganic fertilizers for the dietary nutrients yielding in vegetables Hibiscus sabdariffa. However, the information will economically favor our local farmers and users to adapt the cheapest poultry manure for the optimum yield of qualitative produce vegetable as prospective against malnutrition in Nigeria especially North East where endemically affected by war.Keywords: Roselle leaves, vegetative stage, proximate analysis, elements, Kano

Abstract:

A number of foliar fertilizers were evaluated for their effects on yield and quality of both cantaloupes and honeydews. None of the treatments or treatment combinations resulted in statistical increases or decreases for numbers of cantaloupes or honeydews when compared with the untreated check. A highly significant increase of one treatment regimen (which contained calcium) was noted for cantaloupe weights when compared with the untreated check. Statistical differences were not noted for honeydew weights for this treatment although it also resulted in highest calculated weights of honeydew/area of treatments evaluated. All treatments resulted in numerically higher brix for cantaloupes than the untreated check, thought to be a response to pounds of melons/unit area as the untreated check had the least cantaloupe weight. No differences were noted for cantaloupe seed cavity diameters.

Abstract:

A field experiment with subsurface drip irrigated watermelon was conducted on a Casa Grande s.l. soil at the Maricopa Agricultural Center in 1992 to evaluate the field performance of two slow release nitrogen (SRN) fertilizers in comparison to a conventional soluble N source, urea, ammonium- nitrate (UAN-32). Single, preplant applications of 0, 100 and 200 lbs N/acre supplied from methylene urea (Nutralenes) or 100, 150 and 3(X) lbs N/acre from a methylene urea-ammonium sulfate mixture (MUAS) were evaluated in comparison to treatments of UAN-32 containing from 52 to 445 lbs N/acre made in five split applications. Yield response to N rates above 100 lbs/acre were similar for all three N sources, indicating that a single, preplant application of a suitable SRN material at an adequate rate could provide N efficiently over the entire growing season. The highest numerical yield (49.3 tons/acre) was obtained with a N rate of 150 lbs N/acre from the MUAS material. Monitoring of petiole nitrate levels throughout the season indicated that N release from the MUAS was more rapid and more complete than from the methylene-urea product. At suboptimal N rates, i.e. < 150 lbs N/acre, split applications of UAN-32 appeared to be somewhat more efficient than the slow-release products.

Abstract:

A field experiment was conducted at the Maricopa Agricultural Center on a Casa Grande sandy loam soil to compare the nitrogen (N) utilization efficiency achieved using slowrelease and conventional nitrogen fertilizers under subsurface drip irrigated melon production conditions. 'Mirage' watermelon, 'Laguna' cantaloupe and 'Gallicum' honeyloupe were used as the test crops. Single, preplant applications of three slow - release products (methylene urea, coated ammonium sulfate and coated urea) were compared with the use of urea -ammonium nitrate added in either one or three split applications. The total amount of N applied to all treated plots was 100 lbs. per acre. Whole plant samples were taken four times during the season to determine N uptake patterns. Petioles from the youngest fully expanded leaves were sampled on four dates throughout the season to monitor the N status of all plots. At harvest, total and marketable melon yields were determined. In general, the methylene urea treatment was superior to the use of coated (NH₄)₂SO₄ which in turn was far superior to the coated urea product. The split UAN and preplant UAN treatments had the highest numerical values for total N uptake for all three melon types. However, these values were usually not statistically different from the N uptake in response to the three slow- release N treatments. The type of water delivery system may have reduced the potential advantages of using slow-versus fast-release N fertilizers.

Abstract:

Dentre os diversos agentes existentes no meio ambiente que podem nos expor a diferentes riscos e efeitos, há a radiação ionizante cujo conhecimento da dose é de importância para o efetivo controle e prevenção dos seus possíveis danos aos seres humanos e ao ambiente. A transferência de radionuclídeos dos adubos para/e dos solos para os alimentos podem resultar em incremento na dose interna ao serem consumidos pelo ser humano. Este trabalho avalia a contribuição dos fertilizantes para o aumento da dose de radiação ionizante no meio ambiente e no ser humano. Amostras de fertilizantes, de solos e de hortaliças produzidas em solos adubados foram analisadas através da espectrometria gama com o uso de um detector semicondutor de germânio hiperpuro. Medidas de dose ambiente também foram realizadas com dosímetros termoluminescentes. Nas amostras de solos adubados foram obtidos valores de atividades específicas de 36 a 342 Bq/kg para K-40, de 42 a 142 Bq/kg para U-238 e de 36 a 107 Bq/kg para Th-232. Nas hortaliças os valores variaram de 21 a 118 Bq/kg para K-40 e para os elementos da série do urânio e tório os valores foram menores que 2 Bq/kg. Para fertilizantes o valor máximo obtido foi de 5800 Bq/kg para K-40, 430 Bq/kg para U-238 e 230 Bq/kg para Th-232. As médias dos valores de fator de transferência solo-planta não foram significativamente diferentes entre os tipos de hortaliças analisados. A dose efetiva comprometida anual de 0,882 µSv devido à ingestão de K-40 das espécies estudadas é bem pequena em relação ao valor de referência de 170 µSv dada pela United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR, 2000). A dosimetria termoluminescente forneceu valores de taxa de equivalente de dose ambiente anual entre 1,5 e 1,8 mSv, sem diferenças entre locais cultivados e não cultivados. Através dos resultados obtidos, não foi observada uma transferência significativa de radionuclídeos dos fertilizantes para os alimentos e para os solos nas condições adotadas neste trabalho e conseqüentemente não há incremento de dose de radiação devido à prática da adubação.
Among several agents that exist in the environment which can expose us to different risks and effects, there is the ionizing radiation whose knowledge of dose is of importance to the effective control and prevention of possible damages to human beings and to the environment. The transfer of radionuclides from fertilizers to/and soils to the foodstuffs can result as an increment in the internal dose when they are consumed by the human beings. This work evaluates the contribution of fertilizers to the ionizing radiation dose in the environment and in the human being. Samples of fertilizers, soils and vegetables produced in fertilized soils were analised through gamma spectrometry with the use of a hyperpure germanium detector. Measurements of ambient dose with thermoluminescent dosimeters were also performed. In the fertilized soil samples values of specific activities from 36 to 342 Bq/kg for K-40, from 42 to 142 Bq/kg for U-238 and from 36 to 107 Bq/kg for Th-232 were obtained. In the vegetables the values varied from 21 to 118 Bq/kg for K-40 and for the elements of uranium and thorium series the values were less than 2 Bq/kg. In fertilizers the maximum value of 5800 Bq/kg was obtained for K-40, 430 Bq/kg for U-238 and 230 Bq/kg for Th-232. The average values of soil to plant transfer factor were not significantly different among the types of vegetables. The annual committed effective dose of 0.882 µSv due to the ingestion of K-40 from the analised vegetables is very small if compared to the reference value of 170 µSv given by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR, 2000). The thermoluminescent dosimetry provided the annual ambient dose equivalent from 1.5 to 1.8 mSv without differences between cultivated and non cultivated fields. Through the results obtained, it was not observed a significant transfer of radionuclides from fertilizers to soils and to foodstuffs in the conditions adopted in this work and consequentely there is no increment in the radiation dose due to the practice of fertilization

Abstract:

Field experiments were conducted at four sites in 2005 in the Yuma Valley, AZ (approximately 150 ft. elevation) to evaluate the performance of CN9 fertilizer [a N-calcium (Ca) based fertilizer (9-0-0-11)] in comparison to a conventional N fertilizer source with irrigated melons/cantaloupes (Cucumis melo L.). Each field was divided into two equal (approximately 40 acres) sections. One section received the grower’s N fertilizer source (Conventional) while the other section received the CN9 fertilizer. Basic plant growth and development measurements, aboveground biomass, total and marketable yield, Sugar fruit content as well as total nutrient analysis were among the main variables analyzed. In general, all phenology variables responded similarly between conventional and CN9 treatments. Fresh weight yields ranging from 4,000 to 10,000 kg/ha were observed between conventional and CN9 treatments. Statistical analyses show that total yield between conventional and CN9 was statistically the same; with the exception of the Perriconi site. Similar results were observed for marketable yield. Brix values ranged from 10 to 14 percent, statistical differences for Brix values between the conventional and CN9 treatments were found on the Perriconi and Mason 80 sites where the conventional treatment had higher sugar content in the fruit. Overall, there were no differences in nutrient uptake and allocation patterns due to the addition of CN9 among experimental sites or sampling dates. Regarding the allocation of nutrients in the rind and flesh of melons, the same patterns between treatments at all sites were observed.

Abstract:

Abstract Biofuels have received considerable attention as a more sustainable solution for transportation fuels. Used vegetable oil, normally considered a waste product, has been suggested as a possible candidate. Herein we perform a life cycle assessment to determine the environmental impact of biodiesel fuel produced from waste vegetable oil. We present a cradle to fuel model that includes the following unit processes: growing and harvesting, soy oil processing, cooking, waste vegetable oil refining, transesterification to produce biodiesel fuel and transportation when required. For growing and harvesting, national historical data for yields, energy required for machinery, fertilizers (nitrogen, phosphorous and potassium), herbicides, pesticides and nitrous oxide production are considered. In soy oil processing, crushing and extraction using hexane are included. For cooking, typical fryer performance and food production are considered. In order to determine a mass balance for the cooking operation, oil carryout and waste oil removal are estimated. During waste oil refining, oil is filtered and water removed. Methanol and a catalyst are used in the process of transesterification with glycerin as a byproduct. Transportation is considered using diesel trucks. Data from GREET is used throughout to compute global warming potential (GWP) and energy consumption in terms of cumulative energy demand (CED). Mass allocation is applied to the soy meal produced in refining, oil utilized for cooking and glycerin produced during transesterification. Results are compared to traditional diesel fuel and gasoline. Individual processes are examined to determine possibilities for reduction of GWP and CED. Suggestions are made for improvements in environmental impact using alternative or more efficient methods. The study should provide useful information on the sustainability of biodiesel fuel produced from waste cooking oil.

Abstract:

Biofuels have received considerable attention as a more sustainable solution for heating applications. Used vegetable oil, normally considered a waste product, has been suggested as a possible candidate. Herein we perform a life cycle assessment to determine the environmental impact of using waste vegetable oil as a fuel. We present a cradle to fuel model that includes the following unit processes: soybean farming, soy oil refining, the cooking process, cleaning/drying waste oil, preheating the oil in a centralized heating facility and transportation when required. For soybean farming, national historical data for yields, energy required for machinery, fertilizers (nitrogen, phosphorous and potassium), herbicides, pesticides and nitrous oxide production are considered. In soy oil refining, steam production using natural gas and electricity for machinery are considered inputs. Preprocessing, extraction using hexane and post processing are considered. In order to determine a mass balance for the cooking operation, oil carryout and waste oil removal are estimated. During waste oil processing, oil is filtered and water removed. Data from GREET is used to compute global warming potential (GWP) and energy consumption in terms of cumulative energy demand (CED). Mass allocation is applied to the soy meal produced in refining and oil utilized for cooking. Results are discussed with emphasis on improving sustainability. A comparison is made to traditional fuels, e.g., commercial fuel oil and natural gas. The production of WVO as fuel has significantly less global warming potential but higher cumulative energy consumption than traditional fuels. The study should provide useful information on the sustainability of using waste cooking oil as a fuel for heating.

Abstract:

The leather industry produces a relatively high amount of hard degradable waste, with a negative impact on the environment. This waste usually contains two major categories of residues, namely animal fat and residues containing mostly proteins, suitable for biogas conversion. Obtaining biogas from leather waste by co-digestion with vegetable waste can be a sustainable and eco-friendly alternative to conventional energy from fuels. Anaerobic co-digestion is now considered to reduce waste from various sources and turn it into energy, generating in addition a digestate used as fertilizer in agriculture. This waste is relatively resistant to transformation into an easily fermentable substrate for anaerobic digestion to produce biogas. Thus, the methane yield can be significantly improved by biological treatments with enzymes and enzyme complexes, with microorganisms selected and used as inoculum or by mixed methods, which include other physical or chemical treatments. This paper aims to show the main methods of biological treatment of leather industry waste, in order to increase the yield of biogas by co-digestion with plant materials.

Abstract:

Though urban areas globally cover only about 3% of the earth’s land surface, the UAGs have received a little attention with regards to their ecological facilities. The main aim of this study remains to assess and compare the choice of ecological management options, which guidelines to improvement of environmental-friendly forms of gardening provided by two different UAGs, e.g. Užuovėja (U) and Nemunas (N) in Kaunas distr., central Lithuania. The gardeners were interviewed to identify their preference of different gardening means and reasons for their ecological choices using a questionnaire (n = 60) containing questions about gardening behaviour were surveyed. The interviewed gardeners differ in their commitment and motivation, their agro-ecological practices, and their habits when growing fruits and vegetables. Ecological means, e.g. self-generated compost, turf and organic fertilizer were applied in 43.3-16.7; 16.7-6.7 and 43.3-16.7% in UAGs N and U, respectively. Only 3 or 10% (N) and 4 or 13.3% (U), of respondent regularly used chemical control means regularly. Unfortunately, only 11 or 36.7% (N) and 4 or 13.3% (U) of respondents regularly and sometimes used biological control means. While 7 or 23.3% (N) and 1 or 3.3% (U) of respondents apply biological control means on rare occasion. The large amount of gardeners’, i.e. 63% (N) and 80% (U) employs the natural water resources. This study shows that choice of the urban gardeners for the farming options proceeds the act of production through the conscious manipulation of natural resources, by the means of mobilizing practices (soil improvement, pest control means, watering), as well as supported by knowledge and sustainable viewpoint. Nonetheless, local ecosystem services will support gardener motivation, enhancing knowledge of sustainable gardening, authorizing the rational use of bio-control and soil improvement products, expresses an essential need for rational usage of water and other environmental resources.

Abstract:

Alternative fuels research has been on going for well over many years at a number of institutions. Driven by oil price and consumption, engine emissions and climate change, along with the lack of sustainable fossil fuels, transportation sector has generated an interest in alternative, renewable sources of fuel for internal combustion engines. The focus has ranged from feed stock optimization to engine-out emissions, performance and durability. Biofuels for transportation sector, including alcohols (ethanol, methanol…etc.), biodiesel, and other liquid and gaseous fuels such as methane and hydrogen, have the potential to displace a considerable amount of petroleum-based fuels around the world. First generation biofuels are produced from sugars, starches, or vegetable oils. On the contrary, the second generation biofuels are produced from cellulosic materials, agricultural wastes, switch grasses and algae rather than sugar and starch. By not using food crops, second generation biofuel production is much more sustainable and has a lower impact on food production. Also known as advanced biofuels, the second-generation biofuels are still in the development stage. Combining higher energy yields, lower requirements for fertilizer and land, and the absence of competition with food, second generation biofuels, when available at prices equivalent to petroleum derived products, offer a truly sustainable alternative for transportation fuels. There are main four issues related to alternative fuels: production, transportation, storage, handling and usage. This paper presents a review of recent literature related to the alternative fuels usage and the impact of these fuels on fuel injection systems, and fuel atomization and sprays for both spark-ignition and compression-ignition engines. Effect of these renewable fuels on both internal flow and external flow characteristics of the fuel injector will be presented.
