Desempenho agronômico de cultivares de soja no município de Baixa Grande do Ribeiro - PI

Abstract

Soy (Glycinemax) is one of the main cultivated species in the world, being an important agricultural commodity. Since it is cultivated in different times and regions, it has sought the development of more productive cultivars, resistant to diseases and better adapted to the most varied environments. In this sense, the objective of the study was to evaluate the performance of soy cultivars in the municipality of Baixa Grande do Ribeiro-PI.,,. For this purpose, the experiment was conducted in the 2020/21 harvest, with the following cultivars: TMG 7067 IPRO, DM 6869 IPRO, M 7198 IPRO, FT 3868 IPRO and M 7739 IPRO. Random block design was used with four repetitions, with treatments represented by cultivars of different cycles. The plots were made up of ten 9.75 m long lines, spaced 0.5 m apart, using 5 m of the two central lines as the useful area, disregarding the others on the side, as a border. The variables evaluated were: number of pods per plant, number of seeds per pod, height of plants, weight of 1000 grains and productivity. From the data obtained, it can be concluded that the cultivars M 7739 IPRO and FT 3868 IPRO were more productive in the soil and climate conditions of the municipality of Baixa Grande do Ribeiro-PI.
