CULTIVARES DE SOJA AVALIADAS NO VALE DO PARANAPANEMA, SAFRA 2022/2023

Abstract

The agronomic evaluation of different soybean cultivars was carried out in the municipalities of Assis and Palmital, located at Vale Paulista do Médio Paranapanema, São Paulo State, in the 2022/2023 season, in two sowing moment. The experimental design was completely randomized blocks, with 20 cultivars and 4 replicates per trial, and the means were grouped by the Scott-Knott test at 5% probability. The characteristics evaluated were: plant height (PH), height of insertion of the first pod (HIFP) and grain yield (GY). It was found that there is difference in GY, PH and HIFP among the cultivars evaluated in different environments. Most cultivars studied are agronomically suitable for cultivation in the Vale Paulista do Médio Paranapanema, with advantages for the genotypes indicated by positive interactions with the sites, and may favor the gains to farmers. The cultivars DM 66i68 and AS 3707 showed wider adaptability, with higher GY averages in the 4 evaluated environments, being option of planting in these environments. Considering also the GY, the cultivars CZ 37B43, CZ 37B51 and B 5710 emerge as options for cultivation in soils of more sandy texture while the cultivars ST 2607 and CZ Potent are options for cultivation in places whose soils are clayey texture. The observed GY were higher in October sowings in both sites. Keywords: Agronomic evaluation. Glycine max. Grain yield.
