Seed quality and crop performance of soybeans submitted to different forms of treatment and seed size

Abstract

The objective of this work was to evaluate the effect of different grain sizes and treatments in the physiological quality of seeds and performance of soybean cultures. The object of analysis were seeds from the cultivars Monsoy 5730 IPRO and Monsoy 5947 IPRO, sized 5.5 and 6.5 mm. The industrial seed treatment was carried out in lot equipment, with the products cyantraniliprole, thiamethoxam, metalaxyl, thiabendazole, and a combination of fludioxonil + polymer + talc. The conventional treatment was performed with the products cyantraniliprole, thiamethoxam, metalaxyl, thiabendazole, and fludioxonil. Part of the seeds was kept untreated (control). The experiment used a randomized block design, with four replications. The parameters assessed include the moisture content measurement, seed coating, germination, first germination count, field emergence, survival rate, and grain yield (right after the seed treatment and after 45 days of storage). The industrial treatment method produced a better seed coating. As for seed size, it had no effect on quality or grain yield. Last, the treated seeds presented the best results for emergence in field, while the industrial treatment achieved the highest productivity.

Viability and vigor of soybean seeds as a result of industrial seed treatment and stored in different environments

“…Due to the advantages provided by IST, in the control of pests and pathogens, such as protection and improvement in the initial seedling development, it is justified to investigate the effect of the application, associated or not, of these agrochemicals by means of the referred technique, aiming to check that there is interference in the mode of action of each of them on their respective targets, nor damage to their physiological potential (Soares et al, 2019;R. C. Pereira et al, 2020).…”

Efeito do óleo essencial de palmarosa (Cymbopogon martinii) sobre fungos fitopatogênicos em sementes de soja

“…Apesar da alta produção, uma série de problemas fitossanitários afetam negativamente a qualidade e a produtividade da soja (Soares et al, 2019). Para manter o alto rendimento, algumas medidas preventivas devem ser adotadas no cultivo, visto que cerca de 40 doenças causadas por fungos, bactérias, nematóides e vírus contaminam a soja no Brasil (Finoto et al, 2011).…”
