Resposta da cultivar de feijão IAC2051 em relação a diferentes adubos e formas de aplicação

Abstract

One of the most prominent aspects of Brazilian food culture is beans. To help with the variations in our climate and soil, new technologies have been developed. Soil and plant nutrition are essential for the success of the crop. In Brazil, most soils do not meet the nutrient demands, thus requiring the application of nutrients. In the field, it is essential to optimize any service performed, which is why the broadcast application of fertilizer is being introduced, often even before sowing the cultivar. The study aimed to evaluate the response of the IAC2051 bean cultivar in relation to broadcast and infurrow fertilization. Therefore, an experiment was conducted in the rural area of Dois Vizinhos - Paraná, Linha São Cristovão community, in the 2022/2023 harvest from September to February. The study was composed of a 2 X 3 factorial scheme with subdivided plots, where the main sources were the abubo and the subplots were the forms of application, totaling 18 plots. The fertilizers used were NPK 8-20-20 and Organomineral 7-7-7. Field application was as follows: 100% in the planting furrow, 50% in the furrow, 50% broadcast and 100% broadcast. All applications were made on the day the cultivar was sown. After the end of the crop cycle, the yield components of the bean plant were evaluated. The results showed that the sources and forms of fertilization did not present significant differences in terms of productivity. Broadcast fertilizer application can be used as an operational yield strategy.
