Abstract
Evaluations of cultivar competition are of paramount importance for the indication of these for a given area of cultivation. Thus, the objective of this work was to study the agronomic performance of different soybean cultivars in different locations within the Northwest Region of the State of São Paulo in the 2022/23 season, in order to identify the most suitable cultivars for planting in the region. Cultivar competition trials were installed in 5 municipalities in the Northwest Region of the State of São Paulo (Itápolis, Novais, Orindiúva, Sales and Votuporanga/Meridiano). In the five locations, the experiments were installed in a randomized block design with 3 replications and carried out as recommended for the crop, evaluating grain yield at 13% moisture. The means of the results were grouped using the Scott-Knott test at 5% probability. With the exception of Itápolis, all studied locations showed a favorable performance for soybean production with most of the evaluated cultivars. Most of the cultivars studied are agronomically suitable for cultivation in the Northwestern Region of the State of São Paulo, with emphasis on cultivars CZ26B47, CZ26B55 and CZ37B39. Keywords: Genetical enhancement. Glycine max. Cultivar competition. Productivity.
