The current study was carried out to analyze the effects of agro-nanopolymer preparations application on the seed germination, seedling and root sprout lengths, growth, development, yield, and resistance to Fusarium wilt in Baraka and Selecta-302 soybean variety under laboratory condition. For encapsulation of soybean seeds and nanopreparation UZHITAN, nanochitosan, chitosan (initial), polymer metallocomplexes (PMCs) of copper and silver ions were used at various ratios for nanoascorbate chitosan, ascorbate chitosan, polymer metallocomplex (PMC) Cu2+:Ag 7:3 and PMC Cu2+:Ag 8:2 preparations,. Results of the study revealed a significant effect of these agronanoplymers on the studied soybean varieties; application of this nanoascorbate chitosan, ascorbate chitosan, polymer metallocomplex (PMC) Cu2+:Ag 7:3 and PMC Cu2+:Ag 8:2 showed 17 g, 14.6 g, 13.5 g, and 11.9 g weight of the 1000-grains respectively which was significantly higher than the Gaucho treatment. Further, these agronanoplymers also have a significant effect on the various yield attributes such as number of beans per plant, number of seeds per bean, and seed mass per bean. Application of chitosan and PMC agronanopolemers increased productivity by 4.5-6.1 kg/ha and 3.3-5.1 kg/ha, respectively, compared to the control. Also, the effect of these agro nanopolymer preparations on enzyme activity and protein content was studied in the current study. Among the various tested nanopreparation, the greatest effect on total soybean yield was observed when seeds were treated with nano ascorbate chitosan. All nanopreparation treated seeds has a significant effect on the accumulation of macro and micronutrient accumulation in Soybean seed and except few one rest are the superior to the control and UZHITAN.

Abstract: The objective of this study was to evaluate the spatial variability in soybean seeds quality and in soil chemical attributes of a production field. Data were collected at 138 georeferenced points of a soybean production property located in Santo Antônio de Leverger - MT. Soil related variables, such as phosphorus, potassium, calcium, magnesium, and organic matter (OM) contents, pH, cation exchange capacity (CEC) and base saturation (V%) were evaluated. On the other hand, yield, one thousand seed mass, size, germination, emergence in seedbed, electrical conductivity, accelerated aging and tetrazolium reaction were evaluated as seed variables. The data were submitted to descriptive and geostatistical analysis, and the fit semivariogram parameters were used to elaborate spatial distribution maps of the analyzed variables. After the analysis, it was possible to conclude that there was spatial variability in the evaluated attributes for both seeds and soil related variables, indicating that the soybean seed production area can be divided into management zones, which allows the definition of areas to be harvested or discarded within a field of seed production.

The article presents the data of the field research on the influence of sowing terms with the temperature regime of soil and sowing rates of soybean seeds of Omega Vinnytsia type in the conditions of the Forest Steppe of the Right Bank. It has been determined that sowing terms with the temperature regime of soil at a depth of 10 cm from 6,8,10 and 12 ° C have different effects on growth processes and formation of generative organs on the plant. Optimal sowing periods were the most favourable for intensive growth and development of soybean plants were temperature conditions within 8 and 10 ° C. Sowing at a soil temperature of 10 cm at a depth of 6 ° C reduced the stem height at all seed rates. The height of the lower bean attachment was reduced, as well as the number of beans on the plant and seeds in the bean, while the safety of plants during harvesting was also reduced. Intensive initial growth of soybean crops at sowing at 12° C resulted in increased attachment of lower beans to the stem, but the number of beans per plant and the number of seeds in a bean decreased significantly. The research of the efficiency of sowing soybean types Omega Vinnytsia 600, 700, 800 and 900 thousand germinated seeds per 1 hectare shows at a rate of 600 thousand pieces, stem height, because of their branching, was lower than at the sowing of 700 and 800 thousand n / ha. Also, the height of the lower beans, the number of beans per plant and the number of seeds in the bean were reduced. The highest biometric indicators and the number of generative organs on the plant were observed during sowing with the sowing rate of 700 and 800 thousand n/ha. The increase of soybean seed rate up to 900 thousand n / ha deteriorated biometric indicators of plants and the formation of generative organs. The survival of plants increased at sowing in 6 ° C of soil temperature and with an increase in sowing rate above 600 thousand n / ha. The weight of one thousand seeds changes to a lesser extent depending on the timing of sowing and seed rate and its high indicators were noted at sowing in 8 and 10 ° C and seed rate 700 and 800 thousand n / ha. Increase of soybean seed rate up to 900 thousand n.p. / ha reduces the weight of 1000 seeds against other seed rates for 8-10 years. Years of research were favorable for growing soybeans and obtaining high levels of seed yields. The highest yield of soybean seeds of Omega Vinnytsia variety was obtained at the sowing rate of 10 ° C and it was at the rate of 600 thousand soybean seeds / ha - 36.0 centners / ha; 700 thousand soybean seeds - 44.7 centners / ha; 800 thousand soybean seeds / ha - 40.0 centners / ha and 900 thousand soybean seeds / ha - 38.2 centners / ha. The approximate yield of seeds was obtained at sowing at 8 ° C according to all norms of sowing of seeds in the same regularity as at sowing at 10 ° C. Increase of sowing rate up to 900 thousand n/ha leads to increase of seed yield but also to overspending of seeds and considerable decrease of individual productivity of plants. At the same time, sowing at soil temperature of 6 ° C was more effective than sowing at 12 ° C. and yield was at a rate of 600 thousand seeds. At the same time, sowing at soil temperature of 6 ° C was more efficient than sowing at 12 ° C, and the yield was at the rate of 600 thousand seeds - 27.4 centners / ha, 700 thousand seeds / ha - 33.8 centners / ha; 800 thousand seeds / ha - 29.7 centners / ha and 900 thousand seeds / ha - 30.6 centners / ha. And when sowing at 12 ° C, respectively, 26.4, 31.5, 29.1, 29.2 centners / ha. Key words: sowing dates, sowing rates, plant height, lower bean attachment height, number of beans per plant, number of seeds, seed weight, yield.

Pre-storage seed invigoration treatment in freshly harvested soybean seeds (Glycine max [L.]Merrill, cv. Soyamax) with powdered crude plant materials (red chilli powder@1g/kg of seed; neem leaf powder@2g/kg of seed), chemicals (iodinated calcium carbonate@2g/kg of seed; para-amino benzoic acid and ferulic acid@500mg/kg of seed) and; pharmaceuticals (aspirin @50mg/kg of seed) significantly improved germinability, field performance and productivity over control. Among the treatments, Ferulic acid, aspirin and para-amino benzoic acid showed better results in improving storability and field performance. The wet treatments, soaking-drying showed adverse effect on germinability due to soaking injury. Biochemical studies revealed that the activity of dehydrogenase, amylase (a, b free and b bound), catalase and peroxidase enzymes were higher in all dry treated seeds compared to the untreated control. Among the treatments, ferulic acid followed by aspirin has shown higher enzyme activity. On the basis of the results, pre-storage dry treatments with ferulic acid, aspirin and para-amino benzoic acid may be suggested for improving storability and field performance of stored soybean seed.

Relationships between external cone characteristics (length, width, wet and dry mass), cone quality (total seed mass as a proportion of cone mass, total number of seeds per cone, total seed mass per cone), and number of cones in caches were evaluated for caches of jack pine (Pinus banksiana) cones belonging to red squirrels (Tamiasciurus hudsonicus) in two plantations in southern New Brunswick. Cone length and mass were good predictors of the total number of seeds per cone and total seed mass per cone. Length accounted for a small proportion of the variance of total seed mass as a proportion of cone mass. There was no relationship between the number of seeds or total seed mass per cone and the number of cones per cache.

Доведено, що ступінь фенотипового домінування у гібридів F1 може варіювати від hp > +1 до hp < -1 залежно від компонентів схрещування. Встановлено, що переважна більшість гібридів F1 тривалість веґетаційного періоду та його міжфазних періодів успадковують за типами позитивного наддомінування та позитивним домінуванням. Успадкування висоти рослин відбувається за типами позитивного домінування, проміжного успадкування та за типом негативного домінування. Характер успадкування висоти прикріплення нижнього ярусу бобів у значній мірі визначається поєднанням батьківських компонентів. Так, у першому поколінні у гібридних комбінаціях спостерігається явище наддомінування. За ознаками урожайності та її елементів (урожайність насіння, маса насіння з рослини, маса 1000 насінин, кількість бобів на рослині, кількість насінин із рослини, кількість насінин у бобі) у всіх без виключення гібридів першого покоління спостерігався гетерозис. It was demonstrated that the degree of phenotypic predominance in F1 hybrids can vary from hp to hp < +1 > -1 depending on mating components. The vast majority of the F1 hybrids inherit the length of the growing season and its interphase by type of over& positive dominance. F1 hybrids inherit the height of plants by types of positive dominance, intermediate inheritance and negative domination. The height of the attachment of the lower tier of the beans is largely determined by a combination of parent components. Thus, in the first generation in hybrid combinations there is the phenomenon of over dominance. Due to the yield and its components (seed yield, seed mass per plant, 1000 seeds, number of beans per plant, number of seeds per plant, number of seeds per seedpod) in all first generation hybrids heterosis is observed.

The present research was conducted at the experimental field of Agrotechnology Discipline, Khulna University, Khulna during Rabi season 2016-17 to investigate the growth and yield performance of mustard varieties. The experiment was arranged in a randomized complete block design consisting of eight mustard varieties (viz. BARI Sarisha-8, BARI Sarisha-11, BARI Sarisha-13, BARI Sarisha-14, BARI Sarisha-15, BARI Sarisha-16, Rai and Tori-7) as treatment and replicated thrice. All the growth, yield attributes and yield were substantially influence among the mustard varieties except the phenological parameters. Results of the experiment showed that the highest plant height (131.33 cm), seed yield (1813.33 kg ha-1) and stover yield (3876.67 kg ha-1) were found in BARI Sarisha-16. BARI Sarisha-11 was found better in respect of maximum siliqua plant-1, weight of seeds plant-1, 1000-seed weight and harvest index. Besides this, BARI Sarisha-14 showed the maximum number of seeds siliqua-1. Therefore, findings of this study suggested that BARI Sarisha-16 would be suitable for better productivity and recommended for cultivation in the medium highland of Khulna region of Bangladesh.

Abstract: The analysis of longevity can support decisions about the length of seed lot storage until commercialization, since this characteristic implies the maintenance of viability over time. Seed longevity is analyzed by the p50 test, which expresses the time to lose 50% of the initial viability. Seeds with high vigor and germination have greater physiological potential and, thus, a greater capacity to maintain quality throughout the storage period. However, there has been little research on the correlations between the analysis of p50 (longevity) and the tests used to measure physiological potential (germination and vigor) of lots, which can be used as a tool to make inferences about longevity using the most traditional tests. Thus, the objective of this study was to investigate which tests used to measure the potential of lots can estimate p50. To this end, germination and vigor were evaluated using traditional tests while longevity was assessed in eight soybean seed lots. Correlations and linear regression were tested for the traditional variables versus p50. It was found that the use of accelerated aging, electrical conductivity, and time to 50% radicle protrusion has high potential to estimate longevity as measured by p50.

Significant Difference

Soybean lines lacking lipoxygenase (LOX) activity were compared with soybean lines having LOX activity for the ability to support growth and aflatoxin B1 production by the fungal seed pathogen Aspergillus flavus. Whole seeds, broken seeds, and heat-treated (autoclaved) whole seeds were compared. Broken seeds, irrespective of LOX presence, supported excellent fungal growth and the highest aflatoxin levels. Autoclaved whole seeds, with or without LOX, produced good fungal growth and aflatoxin levels approaching those of broken seeds. Whole soybean seeds supported sparse fungal growth and relatively low aflatoxin levels. There was no significant difference in aflatoxin production between whole soybean seeds either with or without LOX, although there did seem to be differences among the cultivars tested. The heat treatment eliminated LOX activity (in LOX+ lines), yet aflatoxin levels did not change substantially from the broken seed treatment. Broken soybean seeds possessed LOX activity (in LOX+ lines) and yet yielded the highest aflatoxin levels. The presence of active LOX did not seem to play the determinant role in the susceptibility of soybean seeds to fungal pathogens. Seed coat integrity and seed viability seem to be more important characteristics in soybean seed resistance to aflatoxin contamination. Soybean seeds lacking LOX seem safe from the threat of increased seed pathogen susceptibility.

To study adhesion and viability of uredospores of the fungus Phakopsora pachyrhizi on soybean seeds during storage, suspension tests of those uredospores were carried out by washing seeds at each 30 days interval. Furthermore, germination and inoculation tests of uredospores on soybean plants were performed with uredospores collected from seeds of two soybean production areas, located in the municipalities "Chapada dos Guimarães" and "Tangará da Serra", State of Mato Grosso, Brazil. High levels of uredospores infestation were detected before storage [249.31 and 85.18 uredospores/100 seeds (U/100)] on seeds collected in both localities, respectively. After 30 days storage, these figures were 46.12 and 122.5 U/100; at 60 days were 14.62 and 26.62 U/100; and at 90 days were only 2.87 and 3,68 U/100, respectively; dropping to zero after 120 days storage. The percentage of germinated uredospores decreased with increasing storage periods and at 120 days germination percentage was nil. When uredospores were inoculated on soybean plants, rust symptoms were only observed for uredospores collected from freshly harvested seeds. Uredospores associated to soybean seed germinate until 90 days after storage, but are not viable after this time span. Infection of plants only occurs with inoculation of uredospores obtained from freshly harvested seeds.
