Ren, Y., Zhu, J., Hussain, N., Ma, S., Ye, G., Zhang, D. and Hua, S. 2014. Seedling age and quality upon transplanting affect seed yield of canola (Brassica napus L.). Can. J. Plant Sci. 94: 1461–1469. Seedling quality is an essential indicator for seed yield in canola, which is affected by many factors, including seedling age. Two field experiments were conducted to compare canola seedling quality and seed yield on 30-, 35-, 40-, 45-, 50-, 55-, and 60-d-old seedlings in 2011 and 2012. The relationship between seedling quality traits and seed yield of different seedling ages was also analyzed. Results revealed that the highest seed yield obtained from 40-d-old seedlings was attributed to more branches and siliques per plant. The negative effect of young seedlings (30-d-old) on seed yield was greater than that of old seedlings (60-d-old). The reduction rates in seed yield on the 30- and 60-d-old seedlings were 25.7 and 18.2%, respectively, compared with the 40-d-old seedlings. Increased root neck diameter, green leaf number, shoot, and root dry matter was the case on 40-d-old seedling transplanted plants compared with other ages. However, the increase was larger in the old seedlings than in the young seedlings. On average, the shoot and root dry weights of the 30-d-old seedlings were 1.9 and 1.7% of those in the 60-d-old seedlings. However, correlation analysis revealed that the seedlings with the highest shoot and root dry matter did not necessarily obtain the highest seed yield. Factor analysis suggested that the effects of root neck diameter and green leaf number on seed yield were more pronounced than those of shoot and root dry matter. Therefore, high seed yield in canola could be defined in terms of optimum green leaf numbers and branches per plant.

Abstract:
The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh during the period from July to October 2016 to study the effect of age of seedling on the yield and yield contributing characters of short duration Aman rice cultivars. The study consisted two factor A: Variety- three- i) BINA dhan7 (V1), (ii) BRRI dhan56 (V2) and (iii) BRRI dhan62 (V3); and factor B: Number of seedlings hill-1- (i) Single seedling hill-1 (S1), (ii) Two seedlings hill-1 (S2) and (iii) Three seedlings hill-1 (S3). The experiment was laid out in a randomized complete block design with three replications. The highest grain yield was obtained from the cultivar BINA dhan7 which was statistically identical with BRRI dhan56 and this was the consequences of higher number of total and effective tillers hiil-1 and highest number of grains panicle-1. Grain yield was not significantly affected by the number of seedlings hill-1 but numerically the highest grain yield was recorded from single seedling hill-1. From the interaction it is observed that grain yield was not significantly affected by the interaction of cultivar and number of seedlings hill-1. But numerically the highest grain yield was recorded from the interaction of BRRI dhan56 × single seedling hill-1. From the economic analysis it is observed that the highest BCR (1.64) was recorded from single seedling hill-1 in BRRI dhan56 which was close to single seedling hill-1 in BINA dhan7 and the lowest BCR (103) was obtained from two seedlings hill-1 in BRRI dhan62. From the results of the study it may be concluded that BRRI dhan56 with single seedling hill-1 might be cultivated in AEZ-9 for obtaining higher yield and higher economic return in Aman season.Progressive Agriculture 28 (4): 279-286, 2017

Abstract:
To compare some seedling traits with the yield of alfalfa plants when grown as a crop stand, 1000 individually weighed seeds of Beaver alfalfa (Medicago sativa L.) were germinated in a growth chamber in a greenhouse mix containing soil. The dates of emergence and expansion of the first trifoliolate leaf, the weight of the first trifoliolate leaf, and the height, shoot number, leaf number and yield 10 wk after seeding were all correlated with each other. The seedlings were transplanted in late summer in to a 15 × 15-cm grid in the field, simulating a crop stand. Individual plant yields were determined in each of the two succeeding years. The number of shoots present at the first harvest was determined in the seedling year. There was no difference in the mean weight of seeds which emerged and those which did not. The mature plant traits were all strongly correlated with each other (P > 0.001). Although the seed weight and seedling traits had low correlations with mature plant traits (r < 0.25), the top 10% of seedlings on the basis of the date of first trifoliolate leaf expansion or seedling yield exceeded the population (averaged over the two years) by more than 31 and 41% respectively.Key words: Alfalfa, Medicago, seedling, selection, yield

Abstract:
Field experiments were conducted to determine the effect of spring seedling residues of canola (Brassica napus L. and B. campestris L.), barley (Hordeum vulgare L.), flax (Linum usitatissimum L.) and a weed mixture on the growth and yield of subsequent crops of flax and barley seeded after tillage of the seedling plots. Some treatments were also tested without tillage, the seedlings being killed with paraquat. The large quantities of spring seedling residues had variable effects on flax yields, resulting in increases in some years and decreases in others compared to seedling-free plots. Flax yields were generally reduced by canola, flax and weed seedling residues, and increased by barley seedling residue. Averaged over 6 yr, canola seedlings reduced flax yields by 2% and barley increased flax yields by 3% with conventional tillage. On the other hand, barley yields were reduced 7% by conola and 17% by barley seedling residues. Yields of flax and barley were higher without than with tillage of the seedlings prior to seeding. The results are discussed in relation to the effects of the seedling residues on soil crusting, toxic compounds in the residues and toxic compounds formed during decomposition of the residues.Key words: Flax, Linum usitatissimum L., barley, Hordeum vulgare L., plant residues, tillage systems

Abstract:
SUMMARYA survey of the system of rice intensification (SRI)-related literature indicates that different authors have drawn conflicting inferences about rice yield performances under the SRI, chiefly because the SRI methodology has been variously advocated, interpreted and implemented in the field using different rice varieties, seedling ages at transplantation, cultivation seasons and nutrient management regimes. In particular, the SRI method of single-seedling transplantation (SST) has potential economic advantage due to reduced seed costs, but it is not clear whether SST is an effective management strategy across a range of seedling ages, and whether there is any specific seedling age that is optimal for yield improvement of a given rice variety. This is an important consideration in rain-fed ecosystems where variable rainfall patterns and lack of controlled irrigation make it difficult to reliably transplant at a specific seedling age as recommended for the SRI. We conducted a five year-long experiment on a rain-fed organic farm using a short-duration upland and a medium-duration lowland landrace, following the SRI methodology. Rice seedlings of different ages (6, 10, 14, 18 and 28 days after establishment) were transplanted at 25 cm × 25 cm spacing in three replicated plots. The performance for each landrace was examined with respect to productive tillers, panicle density, total grain counts per hill and grain yield per unit area. Performances of seedlings of different ages were compared with that of control plots that employed all SRI practices with the exception that 28-day-old seedlings were transplanted with three seedlings per hill. The results indicate that (1) the SRI can improve mean panicle density if seedling age ≤ 18 days, but that responses differ between varieties; (2) the number of productive tillers per hill is significantly less in SST than that of multiple seedling transplants (MST) of 28-day-old seedlings of both upland and lowland varieties; (3) the total grain numbers per hill of the lowland variety is significantly greater for 14-day-old SST than 28-day-old MST; (4) the grain yield per unit area from young SRI transplants is significantly greater than that from 28-day-old MST for the lowland variety, although the magnitude of the improvement was small; (5) for the upland variety, grain yields declined with the oldest seedlings, but planting multiple seedlings per hill made the yield of the oldest transplants on par with that of younger seedlings planted singly. Our findings suggest that transplanting younger seedlings under the SRI management may not necessarily enhance grain yields.

Abstract:
We planted grafted and seedling chestnuts of six cultivars in Lansing, N.Y., in April 1995 to evaluate performance of the different cultivars in our region and to compare grafted and seedling trees. We used the following cultivars: the Chinese chestnut cultivar Mossbarger (Castanea mollissima) and five interspecific hybrid cultivars [Douglas 1A (C. mollissima × C. dentata), Eaton [C. mollissima × (C. crenata × C. dentata)[, Skioka (C. mollissima × C. sativa), Layeroka (open-pollinated daughter of `Skioka'), and Grimo 142Q (an open pollinated daughter of `Layeroka')]. Growth was not significantly different between cultivars. There were no notable correlations between trunk cross-sectional area at planting and any measurement after the first year. Significant differences between cultivars were found for mortality, yield, and yield efficiency. `Eaton' had the lowest mortality rate (2%) of all cultivars. `Grimo 142Q' and `Layeroka' had the highest dry weight yields and the greatest yield efficiencies, although `Grimo 142Q' had significantly larger nuts than `Layeroka'. In 1998, the largest nuts (5.2 g) were harvested from `Mossbarger' and `Eaton trees'. `Skioka' had the highest mortality (48%), lowest yield, lowest yield efficiency, and smallest nut size. In the first 2 years, most grafted trees showed significantly higher yields and greater yield efficiency than seedling trees. By the third year, differences in yield between grafted and seedling trees were no longer significant for most cultivars. Over the 3 years most grafted trees revealed higher mortality and slower growth than seedlings of the same cultivar. Seedlings did not show more variability in measurements than grafted trees of the same cultivar.

Abstract:
The experiment was conducted at the Agronomy research field of Bangladesh Agricultural University, Mymensingh from July to December 2013 to find out the effect of seedling age and storage duration on growth and yield of wet season rice. The experiment comprised of four ages of seedling (25, 30, 35 and 40-d-old) and four storage durations (0, 1, 2 and 3-days) of uprooted seedlings. Rice var. BRRI dhan52 was used as a test variety. The experiment was laid out in a split-plot design with 3 replications placing seedling age in the main plot and storage duration in the sub- plot. The effect of age and storage -duration of seedling, and their interaction were significant on growth parameters (shoot height, root length, number of tillers hill-1, leaf area index and crop growth rate), grain yield and straw yield. The growth parameters and yield exhibited a trend of decrease with the increase in seedling age and storage duration. All the growth parameters and yield showed highest value in the younger seedlings of 25-d-old with 0-day storage duration of uprooted seedlings while the lowest in the older seedlings of 40-d-old with 3-days of storage duration. The var.BRRI dhan52 produced the highest LAI (8.23), CGR (7.33 mg day-1 hill-1) and biomass (26.87 g) at 60, 45 and 60 days after transplanting. Grain yield reduced by 13, 19 and 37% of 30, 35 and 40-d-old seedlings, respectively compared to 25-d-old seedlings. In case of seedling storage, grain yield reduced by 5, 14 and 31% of 1, 2 and 3-d storage, respectively compared to 0-d storage. For optimum growth and yield of wet season rice, 25-d-old seedlings may be stored up to 1-day after uprooting taking into account the possible delay in transporting seedlings to the flood affected area from the nearby districts.Bangladesh Agron.

Abstract:
Drought is common under rainfed lowlands in Lao People’s Democratic Republic, and with the uncertain onset of rains during the wet season, delay in transplanting results in yield reduction. This study aims to explore ways to ameliorate the negative influence of delayed transplanting on rice crop. A field experiment was conducted for two wet seasons to investigate the effect of seedling age and seedling density on crop performance in terms of grain yield and water productivity. The experiment was laid out in a split–split plot design in four replicates, with seedling age as the main plot, seedling density as the subplot, and varieties as the sub-sub plot. In both years, there were significant seedling age and variety interactions on grain yield. Higher grain yields were observed with older seedlings having stronger tillering propensity. Seedling density did not affect grain yields in both years, but on grain yield components. Shorter duration variety received less supplemental irrigation than longer duration varieties. Late transplanting improved total water productivity but decreased irrigation water productivity due to harvesting delay. The total crop growth duration (from sowing to maturity) was prolonged with transplanting delay. However, the total stay of plants in the main field (from transplanting to maturity) was reduced by 3–5 d for every 10 d delay in transplanting. The results indicated that a good selection of varieties and increasing seedling density improve crop performance and water productivity with delayed transplanting.

Abstract:
A study was conducted at the research field of Horticultural Research Institute, National Research Center (NARC), Islamabad, Pakistan during two consecutive years of 2011 and 2012 to compare the performance of seedlings raised in polythene bags with traditional direct seeding in respect of early harvesting and profitability. Seedlings of three different ages (40, 50 and 60 days old) of vegetable marrow were compared with traditional direct seeded crop. Transplanted seedlings of vegetable marrow produced fruits 36-38 days earlier and availability period of 34-38 days longer than direct seeded crop. Similarly, higher fruit plant-1, fruit weight plant-1 and fruit yield ha-1 were obtained from seedling treatments. Averaged over years, 50-69% increase in yield and 64-100% increase in profit were recorded in seedling treatments than direct seeded crop. Among seedling ages, 60 days old seedlings were the best performer. The overall results of two years study revealed that seedling transplantation was superior to traditional direct seeded practice of growing vegetable marrow and among those 60 days old seedlings was the best in respect of yield components, fruit yield and profit.SAARC J.

Abstract Management practices that overcome low seedling survival and poor tree growth of well-drained, droughty sites can improve their productivity and profitability. This study was established to explore tree and stand growth trends, potential forest product yields, and land expectation values of loblolly pine on a droughty site in response to (1) seedling stock type, (2) subsoiling, and (3) stand density regime. In winter 1993, container (CONT) and bareroot (BARE) seedlings were planted with or without subsoiling at 746 trees per hectare (TPH). BARE seedlings were planted without subsoiling at 1,493 TPH to provide a comparison between low-density treatment combinations and a conventional (CONV) management regime for this site type. Tree growth was monitored periodically through age 13 years. Yield trajectories were estimated by predicting forest product yields with FASTLOB using age 13 years stand characteristics, and land expectation value was determined from revenue predictions and costs associated with each treatment. Low-density regimes that included CONT seedlings or subsoiling before BARE seedling planting improved tree growth through midrotation and had yield estimates comparable with that of a CONV regime. However, land expectation values associated with subsoiling were lower than those of low-density CONT and CONV regimes because of its cost and negligible benefits for seedling survival.

The effects of sulfur-containing amendments (H₂SO₄,Al₂(SO₄)₃ and gypsum) or crust formation, soil chemical properties, seedling emergence and yields of onions (Allium cepa), tomatoes (Lycopersicum esculentum) and chili peppers (Capsicum sp.) were studied on a Pima clay loam soil. Treatments were surface applied on a strip above the seeds. The chemicals influenced the penetrometer index, soil-pH, electrical conductivity, DPTA-extractable soil Fe, Cu, Zn, Mu and seedling emergence in two greenhouse experiments. Gypsum and H₂SO₄ increased seedling emergence while Al₂(SO₄)₃ reduced the soil-pH and EC more than H₂SO₄ and gypsum. Based upon penetrometer readings, H₂SO₄ was the best anti-crusting agent tested followed by gypsum and Al₂(SO₄)₃. At the end of the study, all soil samples were very low in KCl extractable Al, showing that Al toxicity was not responsible for seedling damage. Gypsum decreased levels of Mn and Zn but did not affect Fe and Cu. Al₂(SO₄)₃ increased Fe and Zn, decreased Cu but did not affect Mn. H₂SO₄ did not affect extractable Mn, Cu, Zn and Fe levels. In a field study using two water qualities at Safford, gypsum produced the most tomato seedlings whereas Al₂(SO₄)₃ and H₂SO₄ produced the least. Onion stand counts were not affected by the chemicals with either water. Gypsum, H₂SO₄ and Al₂(SO₄)₃ polymer produced the highest pepper stand counts with the saltier water but there were no differences with lower salt water. Tomatoes produced the highest yield with gypsum and lowest with H₂SO₄ and Al₂(SO₄)₃ with saltier water. With lower salt water, gypsum produced highest yield, followed by the H₂SO₄. Both H₂SO₄ treatments produce low yields. Onions showed no treatment response under lower salt water, while with saltier water, gypsum and H₂SO₄ produced the highest yields. Pepper yields were not affected by amendments with the lower salt water. Al₂(SO₄)₃ polymer, H₂SO₄ and gypsum increased yields with the saltier water. Varieties of peppers and tomatoes produced different yields in response to water quality in a supplementary field study.

Thesis (MScAgric)--University of Stellenbosch, 2004.<br>ENGLISH ABSTRACT: The influence of chemical seed treatments on the germination, seedling survival and yield of canola (cv. Varola 44) was investigated in a series of incubation studies, glasshouse experiments, as well as field trials in the canola producing areas in the Western Cape Province. Incubation experiments were conducted to compare germination and seedling growth of untreated (control) seed with that of seed treated at different application rates (0.5, 1.0 and 2.0 times the recommended) of Cruiser® and SA-combination (which consists of Thiulin® at 0.5g a.i.; Apron® at 0.0815 g a.i.; Gaucho® at 0.6125 g a.i. and Rovral® at 0.9975 g a.i.). The results indicated that seed treatment (all rates of SA-combination and highest rate of Cruiser) delayed germination and seedling growth, especially if the seed was subjected to the Accelerated Ageing Test. Glasshouse studies with pasteurised soil at different water contents, seed sources (storage periods) and planting depths confirmed the phytotoxic effects of the chemical seed treatments in the absence of soil borne pathogens. From the results it became clear that extreme water conditions (very wet or dry) increased the suppressing effect on germination and seedling growth, but that no phytotoxic reactions occurred in moist (favourable soil water conditions) soil, regardless of application rate of the chemicals used, planting depth and seed source. In a second glasshouse experiment conducted in moist soil (kept at 50% of field water capacity to prevent any toxic effects) from seven different localities that were naturally infested with pathogens, both chemicals proved to be effective where soil borne pathogens (Rhizocfonia so/ani and Pythium spp.) occurred. No clear trend could however be found due to either chemical or application rates used. Finally, field trials were conducted to study the effect of chemical seed treatments on the plant populations and yield of canola planted in different row widths (17 and 34 cm) and seeding rates (3, 5 and 7 kq.ha'). Results showed that treated seeds produced more plants.rn" and yielded more than untreated seeds at Roodebloem Experimental Farm, while the highest seeding rate produced significantly more plants.rn" (Roodebloem and Langgewens Experimental Farms), but not significantly higher yields than the lowest seeding rate at the same locality. Although row width did not have an effect on plant population, yield (Roodebloem 2003) was significantly less at the wider (34 cm) rows. As in earlier experiments, no consistent differences between the two chemicals used were found. These results clearly illustrated both the negative (in the absence of pathogens) and positive (where soil borne pathogens do occur) effects that chemical seed treatments may have on the germination, seedling growth and even yield of canola under local environmental and soil conditions. Because no significant differences were found between the chemicals used, both chemicals should be regarded as efficient. More research, especially under field conditions and with more cultivars, is needed before the registration of a chemical for seed treatment could be considered.<br>AFRIKAANSE OPSOMMING: Die invloed van chemiese saadbehandeling op die ontkieming, saailing oorlewing en opbrengs van canola (cv. Varola 44) is ondersoek in 'n reeks inkubasie studies, glashuis eksperimente en veldproewe in die canolaproduserende gebiede in die Wes Kaap Provinsie. Inkubasie eksperimente is uitgevoer om die ontkieming en saailing groei van onbehandelde (kontrole) saad te vergelyk met dié van saad wat behandel is teen verskillende dosisse (0.5, 1.0 en 2.0 keer die aanbevole) van Cruiser® en SA-kombinasie (wat bestaan uit Thiulin® teen 0.5g a.i.; Apron® teen 0.0815 g a.i.; Gaucho® teen 0.6125 g a.i. en Rovral® teen 0.9975 g a.i.). Die resultate het aangedui dat saadbehandeling (vir alle dosisse van SAkombinasie en die hoogste dosis van Cruiser) ontkieming en saailing groei vertraag, veral wanneer die saad onderwerp was aan die Versnelde Verouderings Toets. Glashuis studies met gepasteuriseerde grond by verskillende waterinhoude, saad bronne (stoor periodes) en plantdieptes, het die fitotoksiese effekte van die chemiese saadbehandelings bevestig in die afwesigheid van grondgedraagde patogene. Vanuit die resultate het dit duidelik geword dat ekstreme water toestande (baie nat of droog) die onderdrukkende effek op ontkieming en saailinggroei verhoog het, maar dat geen fitotoksiese reaksies plaasgevind het in klam (gunstige grondwater toestande) grond nie, ongeag die dosisse of chemikalieë gebruik, plantdiepte en saad bron. In 'n tweede glashuis eksperiment uitgevoer in klam grond (gehou by 50% van veldwaterkapasiteit om toksiese effekte te voorkom) van sewe lokaliteite wat natuurlik besmet was met patogene, was beide chemikalië effektief waar grondgedraagde patogene (Rhizoctonia so/ani en Pythium spp.) voorgekom het. Geen duidelike tendens is egter waargeneem vir enige van die chemikalieë of dosisse nie. Laastens is veldproewe uitgevoer om die effek van chemiese saadbehandelings op plant populasies en opbrengs te bepaal van canola geplant in verskillende rywydtes (17 en 34 cm) en saaidigthede (3, 5 en 7 kg.ha-1). Resultate het aangedui dat behandelde saad meer plante.rn" produseer en 'n groter opbrengs lewer as onbehandelde saad by Roodebloem Eksperimentele Plaas, terwyl die hoogste saaidigtheid betekenisvol meer plante.m" (Roodebloem en Langgewens Eksperimentele Plase), maar nie betekenisvol hoër opbrengste gelewer het as die laagste saaidigtheid by dieselfde lokaliteit nie. AI het rywydte nie 'n effek op plant populasie gehad nie, was opbrengs (Roodebloem 2003) betekenisvol minder by die wyer (34 cm) rye. Soos in vroeëre eksperimente is geen konsekwente verskille tussen die twee chemikalieë gevind nie. Hierdie resultate illustreer duidelik beide negatiewe (in die afwesigheid van grondgedraagde patogene) en positiewe (in die aanwesigheid van grondgedraagde patogene) effekte wat chemiese saadbehandelings op ontkieming, saailing groei en selfs opbrengs van canola onder plaaslike omgewings en grondtoestande kan hê. Omdat geen betekenisvolle verskille tussen die chemikalieë gevind is nie, moet beide chemikalieë as doeltreffend aanvaar word. Meer navorsing, veralonder veldtoestande en met meer kultivars, is egter nodig voordat die registrasie van 'n chemiese middel vir saadbehandeling oorweeg kan word.

Abstract:
Influence of tomato (Solanum lycopersicum L.) seedling grafting on the plant growth, fruit yield and quality, and disease tolerance were investigated using 3 cultivars (Big Beef, Celebrity, Cannonball) as scions and two Solanum species (B-blocking, Maxifort) as a rootstock in a randomized complete block design with three replications. The grafted plants were statistically higher in values for stem diameter, leaf chlorophyll, and fruit carotenoid contents. Similarly, the scion/rootstock combination ‘Big Beef/Maxifort’ and ‘Big Beef/B-blocking’ had prolonged days to maturity and gives a higher yield than the non-grafted ‘Big Beef’. Grafting seedling on ‘Maxifort’ and ‘B-blocking’ rootstocks improves the fruit quality like titratable acidity (TA), fruit firmness, but didn’t alter the pH, total soluble solid (TSS), lycopene and TSS/TA. Also, grafted treatment ‘Big Beef/Maxifort’ was found to be a highly disease resistant treatment when compared to the ‘Big Beef’ control with mean relative effect 0.074.

Abstract:
AbstractThe changing climate and water availability strongly affect the current state of agricultural production. While the global temperature rises, the occurrence of extreme climatic conditions becomes erratic. This current scenario has driven the development of rice varieties and cultivation practices that require less water and favor mechanization. Although puddled transplanted rice has been more widely used in the past, direct seeding has been gaining popularity in recent years, especially due to its water- and labor-saving features. This technique allows full crop establishment from seeds that were directly sown in the field, thus avoiding puddling, transplanting, and maintaining standing water. Consequently, it offers promising positive environmental effects including decreasing the release of greenhouse gases and increasing water-use efficiency. Historically, rice varieties bred for transplanting are also used in direct seeding, which limits the maximum yield potential of field trials. The success of direct seeding relies strongly on the development of rice varieties with robust crop establishment. Anaerobic germination, seed longevity, and early seedling vigor are the key traits required to achieve this. This chapter expounds on the physiology, molecular mechanisms, genetics, and relevance of the enumerated traits for direct seeding. A brief discussion of breeding for rice varieties with improved germination under direct seeding is also provided.

Abstract:
The reclamation of new areas or distant lands, which have limited energy and material resources, requires the use of energy saving technologies, which include presowing processing of seeds in magnetic field. The aim of this chapter is to reveal the effect that magnetic field has on seeds and to detect the most effective condition to process seeds in magnetic field before sowing and constructive parameters of the equipment. Magnetic field accelerates chemical reactions, which occur in plant cells, salts and fertilizers dissolve better, and the permeability of cell membranes increases, which accelerates the diffusion of molecules and ions. Due to this, the concentration of ions and oxygen molecules in a cell increases and seeds absorb water better. Presowing processing of seeds stimulate 25–40% seedling emergence and 30–35% germination. The most effective condition of presowing processing of seeds in magnetic field is 0.065 Тl magnetic induction with four times magnetic reversal and 0.4 m/s seed velocity. As a result, agricultural crop yield increases approximately by 20–25%.

Full text
Abstract:
For the estimation of Impact of inadequate concentration of boron in seed storage proteins content in oilseed crops, a sand culture experiment was designed and all the three crops i.e. soyabean, mustard and linseed were grown under sufficient and insufficient boron treatment till maturity. Seed germination and seed storage protein concentration was determined in seeds after the harvesting of crops. Earlier oilseed crops like soyabean, mustard and linseed are cultivated for oil production but at this time these crops are reliable source of protein also and are real asset for human dietary protein. The storage protein present in seeds varies from ~10% (in cereals) to 40% (in certain legumes and oilseeds) of dry weight. Seeds contain one or more groups of proteins that are present in high amounts and that serve to provide a store of amino acids and sulfur required during germination and seedling growth. Quality of seeds is driven by the total protein content present in the form of storage reserve in seeds. There are major four types of storage proteins known as- globulins (insoluble in water), albumins (soluble in water), prolamins (soluble in alcohol) and glutelins (soluble in dilute acid and alkaline medium). Globulins and albumins are the major storage seed proteins of legumes and oilseed crops whereas prolamins and glutelins are mostly found in cereal seeds. Functionally boron is crucial micronutrient for a considerable amount of agricultural yield. Seed reserves (proteins, carbohydrates, starch, lipids) of post harvested seeds are depended on the appropriate boron supply during cropping. Boron insufficiency in oilseed crops found to be an inhibitory factor for seed vigor and seed quality. So this chapter deals with the effect of boron deprivation on seed quality in terms of germination capacity and seed storage protein reserves in the post harvested seeds of soybean, mustard and linseed.

Full text
Abstract:
The role of mycorrhizae in plant growth is well known, such as the ability to increase nutrient uptake, especially phosphate (P), drought tolerance, and resistance to pathogens. It is necessary to understand the application of arbuscular mycorrhizal technology in industrial plant production systems and their impact on agriculture systems. Large-scale nurseries of plantations require proper mycorrhizal application techniques. The relationship of mycorrhizal infection with plant yield (biomass) is known and in the next step, appropriate application time is needed to increase the effectiveness of mycorrhizae in plant growth and yield. Application of mycorrhizal inoculum was more effective in increasing the biomass of sugarcane stem weight to reach 61% with an increase in infection of 41.3%. In addition, the mycorrhizal application increases the root growth of sugarcane seedlings. The root growth promoting ability is important to increase the initial growth of plants after transplanting in dry land under the influence of drought stress, limited nutrients. The application of this technology is expected to increase plant growth, facilitate the maintenance and efficiency of cultivation on an industrial scale.

Abstract:
The study aimed to assess the suitability of slow-release fertilizers in cultivation of napa cabbage in the integrated production system. The objective was realized on the basis of a strict field experiment set up on soil with granulometric composition of light loam. The dose of fertilizer was the first experimental factor, and the fertilizer application was the second factor. The slow-acting fertilizer was applied under each plant during planting of seedlings and in the second variant. The fertilizer was applied in the row, about 5 cm under the seedling root level. On the basis of the results obtained in the experiments, the indices showing nitrogen fertilization efficiency were calculated Fertilization significantly modified the quantity of obtained yield. In the control, without mineral fertilization, the crop yield was 23.32 Mg · ha-1. The largest yield was 52.27 Mg · ha-1. Larger yields and more advantageous productive and environmental efficiency were obtained in objects with row application of fertilizer. The most advantageous agronomic efficiency and nitrogen recovery efficiency were obtained in the combination of 400 kg · ha-1 of slow-acting fertilizer with traditional supplementary PK fertilizers in the case of point application of fertilizers. In the case of row fertilizer application, it is possible to use 50% more of the fertilizer dose without compromising the quality of the crop. Higher doses of free-acting fertilizers increased the standard deviation of the mass of cabbage, which is not desirable for production. The results show that under conditions of low mineral content in the soil, the slow-acting fertilizers can be used at a low level.

Abstract:
Greenhouse tomatoes are divided into early, medium and late-maturing. The days from seedling germination to the first harvest are taken into account. Tomato has a huge potential for heterosis in terms of precocity, overall yield, signs of resistance and uniformity. The preferred agricultural method is hydroponics, which allows you to grow plants without using soil, only using mineral nutrient solutions in water. The cultivation of tomato plants on the " Fitopyramida " will allow to sell their products in the periods with the highest realized prices. An experiment on variety testing of 11 tomato hybrids of different product groups that differ in precocity allowed us to select the most adapted to the conditions of the " Fitopyramida " technology, including the indeterminate beef Ruddy ball F1, cherry hybrids Elf F1 and orange-fruited cherry Magic harp F1. the determinant hybrid Captain F1 showed Good results.

Abstract:
In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.

Abstract:
The expansion of the oilseeds adapted to the soil and climatic conditions of the steppe Crimea will increase the biodiversity on the peninsula and, therefore, maximize the efficient use of its natural potential. Brassica nígra is an insufficiently studied crop under the conditions of the Crimean steppe zone. Therefore, the aim of the research was to study the biological characteristics, seed productivity, and yield quality indicators of some varieties of Brassica nígra in the aforementioned environmental conditions. We studied two varieties of Brassica nígra namely ‘Niagara’ and ‘Smuglyanka’ under rain-fed conditions without any fertilizers. Preceding crop – winter wheat. Cultivation technology – generally accepted. The growing season of ‘Niagara’ variety was 4-7 days shorter than that of ‘Smuglyanka’. This difference was due to the late emergence of seedlings. However, all the following stages of growth and development took place almost simultaneously. In 2017-2019, ‘Niagara’ variety gave the highest yield (0.45 t/ha) exceeding ‘Smuglyanka’ by 0.15 t/ha. The maximum content of fatty oil was in the ‘Niagara’ seeds – 39.3%; ‘Smuglyanka’ contained 24.7%. The main advantage of ‘Niagara’ – high content of essential oil in the seeds (0.96%), which is 3.7 times higher than in the seeds of the ‘Smuglyanka’ variety.
