ROCHA, Renato Santos et al. Agronomic performance of varieties and strains of the soybean under low-latitude conditions in Teresina, PI. Rev. Ciênc. Agron. [online]. 2012, vol.43, n.1, pp.154-162. ISSN 1806-6690.

This study had as its objective to evaluate the agronomic performance of soybean varieties and strains grown under low-latitude conditions in Teresina, PI. Phenological traits, yield, and characteristics related to the development of soybean plants from 32 genotypes taken from pre-launch strains and varieties were evaluated, some already launched in states in the midwest region of Brazil. The experimental design used was of randomized blocks with four replications. Under the conditions studied, 13 genotypes (nine varieties and four strains) were identified as having good agronomic performance in low latitudes, with an average grain yield of over 2,900kg ha-1 (48.3 sacks of 60kg ha-1). Of those genotypes studied, based on certification of BRS Sambaíba and Msoy 9350, those that stood out most for the traits assessed and for satisfactory mechanical harvesting under low-latitude conditions, were the Conquista and Valiosa RR varieties and the strains BCR892 G132, BCR651 G75 and BCR6651 G68.
