SOWING TIMES IN ADAPTATION, STABILITY, PRODUCTIVITY, AND OIL AND PROTEIN CONTENTS OF SOYBEAN GENOTYPES1

ABSTRACT No isolated factor influences soybean development and production more than the sowing date, but responses of cultivars sown on different dates depends their sensitivity to environmental conditions. Thus, this study evaluated adaptability stability 17 genotypes in relation yield, as well grain oil protein contents a function times. The experiment was designed randomized blocks with three replications × 5 factorial scheme. were: Conquista, CD 223 AP, Elite, Garantia, Bioagro lineage, M-Soy 8400, M-soy 8001, Nambu, Sambaíba, Esplendor, UFVS 2006, 2005, UFVTN 102, UVF 18, UFV 16, Valiosa, Vencedora, five SD1 = 11/3, SD2 11/20, SD3 12/07, SD4 12/23, SD5 01/09. 18 Garantia showed high contents, adaptation all when most favorable dates. were adapted stable had higher other genotypes, regardless date. presented yields early December. findings indicate that genotype is suitable for growing conditions central-north region state São Paulo.
