Abstract
In the search for maximum productivity, it is essential to know the response of cultivars in different regions and in their particular microclimates, in order to select the best available genetic material. Thus, the objective of this work was to study the agronomic performance of different soybean cultivars in different locations within the Southwest Region of the State of São Paulo in the 2022/2023 season, in order to identify the most suitable cultivars for planting in the region. Cultivar competition trials were carried out in 3 municipalities in the Southwest region of the State of São Paulo (Adamantina, Andradina and Assis) in an experimental design in randomized blocks with 3 replications and carried out as recommended for the crop, evaluating the grain yield at 13% humidity. The means of the results were grouped using the Scott-Knott test at 5% probability and a joint analysis of the experiments was carried out. All tested cultivars are agronomically able to be produced in the southwestern region of the State of São Paulo, however they presented modest yields in the 2022/23 season if considered as a whole. However, the selection of cultivars with specific adaptability for each locality increases productivity gains. Keywords: Adaptability; Genetical enhancement. Glycine max. Cultivar competition. Yield.
