ADAPTABILIDADE DE CULTIVARES DE SOJA DO PROGRAMA DE MELHORAMENTO DA UFV À REGIÃO LESTE DE GOIÁS

Abstract

The positioning of varieties adapted to the region's climate is important for standardizing productivity. Thus, the objective of this project is to carry out two cultivation and use value trials with varieties from the UFV program in the municipality of Cristalina-GO. The experiment was conducted at two locations in the municipality of Cristalina-GO in the 2022-2023 harvests. The first location was the Experimental Station of IF Goiano Campus Cristalina (latitude 16o 49' S and longitude 47o 36' W) and the second at Fazenda São Geraldo (latitude 16o 50' S and longitude 47o 48' W). The design used was randomized blocks, with 3 replications, testing 25 soybean varieties with 5 commercial controls adapted to the region. The main characteristics evaluated were population and grain yield. The average final plant population was 140,000 and 122,840 plants per hectare at the São Geraldo farm and at the Experimental campus of IF Goiano and at the São Geraldo farm. The average productivity was 1,058 and 2,726 kg/ha at the Experimental campus of IF Goiano and at the São Geraldo farm, respectively. Variety 1115 stood out at the Experimental Campus with 29.7 bags/ha, while variety 1178 stood out at the São Geraldo farm with a productivity of 67.2 kg/ha. Despite the divergence of results in the two locations, varieties 1115 and 1165 stood out in both environments in the municipality of Cristalina, and could be two options to be analyzed as potential positioning for the region in subsequent trials
