Manejo de adubação organomineral de base para a produção de soja na Região Sul

Abstract

Soybean culture is of great importance in the Brazilian economic scenario, and as in other cultures, the high productivity and profitability of the process are the desired aspects. In this context, the adoption of proper practices in the production of seeds and grains are essential to achieve high yields. The use of quality seeds, as well as the correct nutritional management are essential factors to achieve high yields. Thus, this study aimed to evaluate the performance of soybean in the municipality of Capão do Leão, subjected to sources and doses of basic fertilization in the 2018/2019, 2019/2020 and 2020/2021. The treatments consisted of the following combinations: 350 organomineral (T1), 350 mineral (T2), 420 organomineral (T3), 210 organomineral + 240 potassium chloride (T4), 210 mineral + 240 potassium chloride (T5) and 268 of organomineral + 240 kg/ha of potassium chloride (T6). The experimental design used was a randomized block design, and the yield components and physiological quality of the produced seeds were evaluated. For the analyzed variables of productivity and agronomic characteristics, the treatments showed no statistically significant difference, except for first germination count.
