Produção de soja na região nordeste paulista, safra 2022/23

The inappropriate choice of cultivar in a given region can compromise grain yield. Thus, it is of paramount importance to be aware of the interaction between genotypes and the environment. Thus, the objective of this work was to study the agronomic performance of different soybean cultivars in different locations within the Northeast 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 tests were installed in 5 municipalities in the Northeast Region of the State of São Paulo (Jaboticabal, Mococa, Mogi-Mirim, Pirassununga and Ribeirão Preto). In the five locations, the experiments were installed in a randomized block design with 3 replications and conducted 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. Of all the locations studied, Jaboticabal and Pirassununga presented the most favorable conditions for soybean production with most of the evaluated cultivars. In the 2022/23 season, the BS2606, NS6446, TMG 2265, BMX COMPACTA, CZ26B47 and BMX FIBRA cultivars stood out for the Northeast Region of the State of São Paulo.
