Efeito da semeadura a seco e tratamento de sementes na emergência, rendimento de grãos e outras características da soja [Glycine max (L.) Merrill]

Abstract

The experiment was carried out at Federal Universidade of Lavras, on a soil classified as Distrophic Dusky Latosol in the agricultural year 94/95. The experimental design was a randomized blocks in factorial scheme 2 x 4: treated seeds with fungicides Vitavax/Thiram P.M.; and untreated seeds and four time of dry (0, 7, 14 and 21 days after sowing). The sowing was realized in dry soil (6% moisture content), using the Doko cultivar. The soybean seeds sowed in the dry soil, presented great performance up to 14 days, not being altered the grains yields, providing to the farmer a larger flexibility in the sowing date. Although, the fungicides treatments, altered the initial and final stand significantly, they did not provide increases in the grains yields.
