The assay was conducted in Pelotas, Rio Grande do Sul-Brasil, to compare the effect of used engine oil with to paraquat (Gramoxone) applied during the physiological maturition of soybean seeds (Glicyne max (L.) Merrill), Bragg variety. The oil doses were 5.3, 8.5 and 12 l/ha. The desiccation intensity was determined and 30 pods per plot were periodically collected to follow the humidity content of the seeds, to 18%. The humidity was later reduced to 10.5 +0.5 and 2.0 kg of seeds were stored, in cotton bags,during 6 months under the environmental conditions at the Centro de Entrenamiento de Semillas of the Federal University of Pelotas. The seeds were subjected to germination, vigor and phytosanitary tests at harvest time and after 3 and 6 months of storage. Under the conditions of this trial, the doses of 12 l/ha of oil and 2 l/ha of paraquat: a) act as desiccants for soybean plants, b) favors the production of seeds with better viability and vigor after 6 months of storage and c) guarantied better sanitary seed quality after 6 months of storage.

Abstract: Chemical treatment of soybean seeds is very important to ensure successful crop establishment. However, problems such as phytotoxicity of product combinations that can reduce seed physiological performance require attention. The use of computational resources has shown potential in identifying phytotoxic effects and contributing to the steps of quality control of treated seeds. The aim of this study was to determine if computerized image analysis of seedlings enables the phytotoxicity of chemical treatment of soybean seeds to be assessed in an effective and simplified manner. Samples from two soybean seed lots were treated with fungicides, insecticides, micronutrients, and their combinations, as well as with polymer and drying powder (coatings). After chemical treatment, the seeds were evaluated for germination, first germination count, seedling emergence in sand, accelerated aging, and seedling performance with and without the correction of regions not automatically demarcated (Vigor-S). We found high correlation of the Vigor-S parameters with the traditional tests for detection of phytotoxic effects of chemical treatment, regardless of correction made in the system. Computerized image analysis of seedlings is an effective and highly sensitive resource for evaluating possible phytotoxicity effects due to chemical treatment of soybean seeds.

Abstract: Seed processing or conditioning is important for improving soybean seed lot quality as it improves the physical characteristics by eliminating inert materials, weed and non-standard seeds and increases physiological quality. The objective of this study was to evaluate the effect of processing on physical and physiological qualities of soybean seed, before and after each equipment and transport system, during processing in a Seed Processing Plant. Samples of six cultivars were obtained during processing while seeds passed through each machine, totaling fifteen sampling sites. The experimental design was entirely randomized, treatments arranged in 15 x 6 factorial scheme, with 10 replications. Characteristics evaluated were germination; vigor by accelerated aging test; tetrazolium test for viability (TZ 1 to 5), vigor (TZ 1 to 3), weathering damage (TZ 3), mechanical damages (TZ 2 to 8), stinkbug damages (TZ 2 to 8) and moisture content. Results showed that processing improves the physiological and physical qualities of soybean seeds and enhances average quality seeds. The equipment and the system of transport (lifts and conveyor belts) used in this study did not cause mechanical damages to the seeds; the mechanical damages were mostly detected in larger seeds and stinkbug damages were found in smaller seeds; and seeds with weathering damage were neither eliminated nor reduced by any processing line.

Abstract: This study aimed to compare the results of germination, vigor, and yield of high- and low-vigor soybean seeds submitted to on-farm application of biostimulant with its application via industrial treatment 60 days before sowing. The experimental design was a factorial arrangement of 6 × 2 × 2 (technology × vigor level × strategy of biostimulant application) for the laboratory experiment and of 6 × 2 (technology × strategy of biostimulant application) for the field experiment. Germination, accelerated aging, emergence in sand, seedling dry biomass, and electrical conductivity were assessed in the laboratory, while stand, one thousand-grain weight, and yield were assessed in the field. Biostimulant application in soybean seeds not coated with pesticides did not affect the physiological quality regardless of the application moment (at the day of sowing or at 60 days before sowing). However, when applied in seeds coated with fungicides and insecticides, better results of germination, vigor, and yield were obtained with the on-farm use of biostimulant.

ResumoDurante o armazenamento as sementes ou grãos podem sofrer alterações em sua composição química, em razão do ambiente de estocagem. Diante disto, a produção de sementes de alta qualidade fisiológica dependerá do somatório de todos os atributos genéticos, físicos, fisiológicos e sanitários. Entretanto, pouco se sabe sobre os efeitos nas sementes por meio da operação de colheita, secagem beneficiamento e armazenamento por longos períodos de tempo. Por isso, foi conduzido no laboratório de sementes da Universidade de Rio Verde, este estudo com o objetivo de avaliar a qualidade fisiológica de sementes tratadas sob diferentes condições de armazenamentos. O delineamento experimental utilizado foi o inteiramente casualizado 2x5x7, sendo duas condições de armazenagem (armazém convencional e climatizado), cinco tratamentos de sementes e sete épocas de avaliação, com quatro repetições. Aos 0, 20, 40, 60, 80, 100, 120 dias após a imposição dos tratamentos foram avaliadas germinação, índice de velocidade de emergência, envelhecimento acelerado e comprimento de raiz. Os tratamentos químicos aplicados nas sementes de soja (cultivar M 7739 IPRO) reduziram o vigor das sementes.Palavras-Chave: Glycine max, germinação, vigor.AbstractDuring storage as seeds or grains may suffer in their chemical composition, because of the storage environment. In view of this, a production of high quality physiological seeds will depend on the sum of all genetic, physical, physiological and sanitary attributes. However, little is known about the effects of seeds by harvesting, drying, processing and storage for long periods of time. Therefore, it was conducted in the seed laboratory of the University of Rio Verde, in order to evaluate a physiological quality of seeds treated under different storage conditions. The experimental design was used for the completely randomized 2x5x7, two storage conditions (conventional and air conditioned warehouse), five seed treatments and seven evaluation periods, with four replications. At 0, 20, 40, 60, 80, 100, 120 days after an imposition of treatments for evaluated germination, emergence speed index, accelerated aging and root length. The chemical treatments applied in soybean seeds (cultivar M 7739 IPRO) reduced seed vigor.Keywords: Glycine max, germination, vigor.

Different Doses

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.
