Soybean yield as a function of sowing season

This study aimed to evaluate the grain yield of soybean cultivars as a function different sowing seasons and soil types, in Western region São Paulo state. Two experiments were performed district Gardênia, municipality Rancharia-SP two types (Red Argisol with medium sandy texture Red Nitosol very clayey texture). For both studies, randomized block design 5 x 2 factorial scheme arranged strips was adopted. The factors consisted five (October 21st; November 4th; 18th; December 2nd 16th) (TMG 7060 IPRO TMG 7062 IPRO). on October 21th 4th showed highest rates plant growth yield, regardless texture. Grain similar among studied In Nitosol, cultivar had higher productivity sowings 18th 2nd.
