Different herbicides were applied to soybean plants in field plots planted to different soybean cultivars located at four locations in Illinois between 1997 and 2000. Treatments varied from hand weeded to preemergence herbicides to postemergence herbicides. Soybean seeds were harvested and evaluated for different seed quality parameters. The percentage of seeds infected with Phomopsis spp. ranged from 1 to 40%, and the percentage of seeds infected with Cercospora kikuchii was low, ranging from 0 to 4%. Herbicides had little or no effect on seed quality parameters such as percent germination and incidence of seed pathogens or on protein and oil concentrations. Soybean seed quality was affected by Phomopsis spp. in that there were significant (P ≤ 0.05) inverse correlations between Phomopsis spp. incidence and percentage seed germination. It appears that Phomopsis spp. may be a more prevalent seed pathogen than C. kikuchii for soybean fields in central to northern Illinois.

Soybean seed treatment contributes to the maintenance of seed quality, but the effect of commercial formulations and chemical products on the effectiveness of the electrical conductivity test based on electrolyte leaching has been frequently questioned. This study aimed to verify the interference of the chemical seed treatment of two soybean cultivars on the effectiveness of the electrical conductivity test in evaluating the vigor of freshly treated and stored seeds. The experimental design was completely randomized, consisting of seven seed treatments and two evaluation periods (0 and 60 days after storage), with four replications. The used seed treatments consisted of 1) fipronil + pyraclostrobin + thiophanate-methyl, 2) imidacloprid + thiodicarb + carbendazim + thiram, 3) abamectin + thiamethoxan + fludioxonil + mefenoxam + thiabendazole, 4) carbendazim + thiram, 5) fludioxonil + mefenoxam + thiabendazole, 6) carboxin + thiram, and 7) control (no treatment). The cultivars were BRS 360 RR and BRS 284, which were analyzed separately. Germination, accelerated aging, emergence, and electrical conductivity tests were carried out. No differences were detected between the control and chemical treatments performed on seeds of the two freshly treated soybean cultivars regarding germination, accelerated aging, and emergence tests. The germination test stood out after storage with the cultivar BRS 360 RR, showing the maintenance of germination potential for seeds treated with carbendazim + thiram and the control treatment. Therefore, the chemical treatment of soybean seeds interferes with the result of the electrical conductivity test. The electrical conductivity test is effective in segregating seed lots in terms of vigor level. The electrical conductivity test correlates with the other vigor tests used to identify the reduction in the physiological seed quality with storage.

ABSTRACT The use of an appropriate method that accurately expresses physiological seed quality and minimizes possible phytotoxicity by chemical products in laboratory testing with soybean seeds is relevant. The objective of this work was to evaluate the influence and infer the method adequacy for the representative evaluation of physiological quality of soybean seeds treated with phytosanitary products. Two experiments were carried out in a completely randomized design, with trial 1 in a 9×5 factorial scheme involving nine seed treatments, including fungicides and insecticides, and solutions with five osmotic potentials (0, -0.25, -0.5, -0.75 and -1.0 MPa) for wetting a paper substrate in a germination experiment, with evaluation of the normal seedlings at five and eight days after sowing. The second experiment consisted of a 9×7 factorial, with nine seed treatments and seven methods for germination evaluation at 5 days (between paper - BP, between sand - BS, between paper with water restriction - BPWR, between paper with preconditioning - BPC, sand between paper - SBP and vermiculite between paper - VBP). Treatments with insecticides affect seedling germination and evaluation, with greater phytotoxicity in relation to fungicides. Methods with readily available water led to greater phytotoxicity than methods with low water availability. For soybean germination evaluation of seeds treated with phytosanitary products, the BPC, SBP and VBP methods were optimal.

Seed treatment with beneficial microbes or biocontrol agents is called biological seed treatment. Vegetable seed quality includes the physical, pathological, genetic and physiological that leads to successful crop establishment and yield . Use of BCA’s as seed treatments can play an important role in most aspects of seed quality, and be of particular benefit for improved seeding growth under stressful conditions. It not only improve the quality of seed but also protect seed from different seed borne diseases and make the seed healthy.

Yield And Quality

ABSTRACT The use of growth-promoting bacteria can increase the yield and quality of seeds of several annual crops, such as soybean. Based on that, the present study aimed to evaluate the effects of the inoculation of Bacillus subtilis strains on seed treatment, evaluating the yield and quality of seeds of two soybean cultivars. The experiment was conducted in a conventional system, in an Oxisol of clayey texture, in a crop under sprinkler irrigation. The experimental design was randomized blocks, arranged in split plots with four repetitions. Treatments were composed, in the plots, of two soybean cultivars: M7110 IPRO and Brasmax Desafio RR. Within the levels of subplots, the treatments consisted of inoculation and doses of inoculant: Bacillus subtilis Pant001 strain at doses of 0, 2, 3, 4 and 5 mL kg-1, and QST713 strain at the recommended dose of 2 mL kg-1. Inoculation with the strains Pant001 and QST713 increased the yield of both soybean cultivars tested, besides improving seed quality due to the increase in the concentration of total storage proteins, seedling emergence percentage and seed vigor by the accelerated aging test.

Understanding of sowing in an ideal season for each region and cultivar is essential for the crop to reach each of its stages in more favorable climatic conditions. The objective of this study was to evaluate the influence of different sowing times on agronomic attributes of two soybean cultivars and the physiological quality of soybean seeds in soil type Eutrophic Haplic Planosol. The experimental design was completely randomized, in a factorial scheme 4 x 2, with four sowing times and two soybean cultivars, with eight replications. The sowing was executed at the beginning and end of November (1st and 2nd epochs) and beginning and end of January (3rd and 4th epochs), using the cultivars: Fundacep 64 RR and BMX Potência RR. The experiment was carried out in polyethylene vessels with volumetric capacity of 10 liters. The morphological attributes of the plants were evaluated, such as: height, stem diameter, number of pods and seeds per plant, 1000 seed weight, as well as seed germination and vigor. Seeding after January 1st negatively affected the agronomic behavior of soybean plants, with reduction of plant height, stem diameter, number of pods and seeds per plant. The sowing on November 1st favored the obtaining of seeds with lower physical quality in terms of 1000 seed weight; however, seeds with superior physiological performance. Late sowing showed an alternative for the production of soybean seeds in the South region of Rio Grande do Sul, mainly due to the higher quality of the seeds produced in this period.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.
