Industrial treatment in soybean seeds: physiological quality and culture performance

Abstract

This study aimed to evaluate the physiological quality and the crop performance of soybean seeds submitted to the industrial and the conventional seed treatment process. Soybeans seeds of the cultivars FPS Urano RR, Syn 1059 RR and Syn 1163 RR were treated with Standak Top® (Pyraclostrobin + Thiophanate-methyl + Fipronil) at the dose of 200 mL 100kg-1 of commercial product + 100 mL 100kg-1 of the polymer. The treatments consisted of control, conventional and industrial treatment. In the field, we evaluated the emergence, the dry mass and the grain yield in two times of sowing. Seed coverage and physiological quality of seeds (germination tests, first count of germination and seedling emergence) were evaluated at the laboratory after treatment and at 30, 90 and 150 days of storage. Conventional and industrial seed treatment does not affect the germination of high vigor seeds (Cultivars Syn 1059 and Syn 1163) and increases the percentage of normal seedlings in low vigor seeds (Cultivar FPS Urano). The industrial and conventional seed treatment improve the emergence of the soybean crop and potentiates grain yield in soybean cultivars of high physiological quality.
