This experiment was carried out to evaluate the effect of the honeybee pollination in the production and quality of soybean seeds (Glycine max L. Merril). Seed production was higher (P=0.0001) in covered areas with honeybee colonies (50.64%) and uncovered areas (57.73%) than in covered areas without honeybee colonies. It could be concluded that honeybees were responsible for 95.5% of the pollination accomplished by insects. The pod number in covered treatment with honeybees was 61.38% higher (P=0.0002) than in the covered treatment without honeybees. The average weight of 100 seeds was larger (P=0.0001) in the area covered without honeybees, and reached 17.8 g. The medium content of crude protein in grains was 36.7% and the average oil content was 20.2%. The germination test did not show differences (P>0.05) among the seeds in different treatments. It was concluded that the honeybee pollination in the soybean increased the seeds production.

RESUMOA soja é uma das culturas mais cultivadas do planeta, sendo o Brasil, um de seus maiores produtores. É uma fonte barata e rica de óleo vegetal. O tratamento de sementes é amplamente utilizado para evitar perdas por patógenos e insetos na fase inicial do estabelecimento das plantas. Sendo uma das formas de se evitar a perda da qualidade. O objetivo deste trabalho foi avaliar o efeito do tratamento químico com inseticida/fungicida e polímero na qualidade final das sementes de soja. Foram utilizadas sementes do cultivar M-7110 Ipro, produzida na safra 2016/17 na região de Rio Verde, GO, com grau de umidade de 12%. Os tratamentos de sementes utilizados foram: Testemunha, Caixa vigor e praga (200 mL de Cruiser+ 100 mL de fipronil + 100 mL de Maxim XL); 100 mL + 100 mL de Standak + Maxim XL (Fipronil 250 g/L + Metalaxil-M 10 g/L e Fludioxonil 25 g/L) e 300 mL + 100 mL de Cropstar + Maxim XL (Imidacloprido 150 g/L e Tiodicarbe 450 g/L + Metalaxil-M 10 g/L e Fludioxonil 25 g/L). Foram utilizados o teste de germinação, emergência e a taxa de crescimento de plântulas. O tratamento Cropstar + Maxim XL se destacou como o melhor para o tratamento das sementes de soja quando comparado aos outros tratamentos utilizados neste trabalho. O uso de Standak + Maxim ML foi inferior aos demais para o tratamento de sementes de soja.Palavras-Chave: tratamento de sementes; Glycine max; vigor.ABSTRACTSoy is one of the most cultivated crops on the planet, being Brazil, one of its largest producers. It is a cheap, rich vegetable oil fountain. Seed treatment is widely used to avoid losses by pathogens and insects in the early stages of plant establishment. Being one of the ways to avoid the loss of quality. The purpose of this work was to evaluate the effect of chemical treatment with insecticide/fungicide and polymer in the final quality of soybean seeds. Seeds of cultivar M-7110 Ipro, produced in the harvest 2016/17 in the region of Rio Verde, GO, with a moisture content of 12% were used. The seeds treatments used were: Control, Caixa vigor e praga (200 mL de Cruiser+ 100 mL de fipronil + 100 mL de Maxim XL); 100 mL + 100 mL de Standak + Maxim XL (Fipronil 250 g/L + Metalaxil-M 10 g/L e Fludioxonil 25 g/L) e 300 mL + 100 mL de Cropstar + Maxim XL (Imidacloprido 150 g/L e Tiodicarbe 450 g/L + Metalaxil-M 10 g/L e Fludioxonil 25 g/L). The germination test, emergency and the growth rate of seedlings were tested. The treatment Cropstar + Maxim XL stood out as the best for treating soybean seeds when compared to other treatments used in this work. The use of Standak + Maxim ml was inferior to the other for the treatment of soybean seeds.Keywords: seed treatment; Glycine max; vigour

Soybean (Glycine max (L) Merr) is needed as an alternative diversification in order to increase protein consumption. Soybean can be processed into variety of foods and drinks. The most popular drink from soybean is soya milk which is made from soybean extract yielded from the addition of water. The amount of water added determine the quality of soya milk due to its effect on the chemical and physical properties of soya milk. This research was intended to find out the proper ratio of soybean and water in the processing of soya milk to yield the best quality. A completely randomized design was used with eight treatments of soybean and water ratio as follows, ratio of 1 : 6, ratio of 1 : 8, ratio of 1 : 10, ratio of 1 : 12, ratio of 1 : 14, ratio of 1 : 16, ratio of 1 : 18 and ratio of 1 : 20. Result showed the soybean and water ratio 1 : 10 in the processing of soya milk yielded milk having good quality according to its chemical with protein content of 2.53%, fat of 1.20%, sugar total of 1.60%, pH of 7.1, and organoleptic characteristies of both somewhat sweet taste and viscous texture.

Post-extraction soybean (Glycine max (L.) Merr.) meal is widely used as a basic protein feed for farm animals, especially poultry and pigs. Products made from unmodified soybean seeds are an alternative to imported GMO soybean meal. The aim of the study was to develop feed products from popular European varieties of genetically unmodified soybeans, which can be produced on small and medium-sized farms, and to assess their nutritional value and safety to livestock. The research was conducted on the seeds of three soybean varieties and two types of feed products resulting from thermobaric treatment (extrudate) and oil pressing (soybean press cake). The mould and yeast contamination of domestic seeds was negligible. The thermobaric and pressing treatments lowered the content of fungi by 97%. The products were considered free from mycotoxins. In comparison with full-fat soybean seeds, the protein content in the products was up to 19% higher, and 92% of the total lysine remained available. The products had lower content of antinutritional ingredients (trypsin inhibitors) and the urease activity was reduced by 52–59% and 99%, respectively. The experiment showed that the European genetically unmodified soybean feed products were characterised by good quality, mycotoxicological purity and high nutritional value for farm animals.

The fungus are the main microorganisms present in seeds, is the main cause of deterioration and loss in production. The anthracnose caused by C. truncatum associated with soybean seeds as has main vehicle for introduction into the planting areas can be detected in all stages of crop development, from the cotyledons to the end of the cycle, being present in the stems, veins, leaflets and pods. Thus aimed to evaluate the influence of using different products fungicides as seed treatment, where the seeds were inoculated with the pathogenic fungus and treated with the chemicals They take Carbedazim + Fludioxonil + metalaxyl-M and carboxin + thiram. For each fungicide product was two tramentos done using the doses recommended by the manufacturer and 75% of dose. We evaluated health, germination and promote plant (Plant growth, fresh weight and dry weight of root and shoot). This work concludes that the use of fungicide controls significantly seeds infected with C. truncatum and presents a significant improvement as the development of structures seedling.

Soybean [Glycine max (L.) Merr.] is one of the most important legume crops abundant in edible protein and oil in the world. In recent years there has been increasingly more drastic weather caused by climate change, with flooding, drought, and unevenly distributed rainfall gradually increasing in terms of the frequency and intensity worldwide. Severe flooding has caused extensive losses to soybean production and there is an urgent need to breed strong soybean seeds with high flooding tolerance. The present study demonstrates bioinformatics big data mining and integration, meta-analysis, gene mapping, gene prioritization, and systems biology for identifying prioritized genes of flooding tolerance in soybean. A total of 83 flooding tolerance genes (FTgenes), according to the appropriate cut-off point, were prioritized from 36,705 test genes collected from multidimensional genomic features linking to soybean flooding tolerance. Several validation results using independent samples from SoyNet, genome-wide association study, SoyBase, GO database, and transcriptome databases all exhibited excellent agreement, suggesting these 83 FTgenes were significantly superior to others. These results provide valuable information and contribution to research on the varieties selection of soybean.
