Potencial produtivo e teor de proteína de feijão sob efeito residual de doses de cama aviária e fertilizante mineral

Abstract

Poultry litter has been studied and used as an alternative fertilizer in agricultural production due to its efficiency in supplying n, p, k and ca to the system, in addition to improving the physical conditions of the soil. This experiment was developed at the Universidade Tecnologica Federal do Paraná– campus Dois Vizinhos, at the dry season 2022/2023 and the cultivar used was IPR Sabiá in an area where fertilization protocols with poultry litter have been carried out since 2012. The work aimed to evaluate the yield components, bean productivity as well as protein content of the grain under the residual effect of different doses of fertilization with poultry litter and mineral fertilizer, these being: 0 t ha-1, 3 t ha-1, 6 t ha-1 and 9 t ha-1 of poultry litter, in addition to a comparative treatment with 100 kg ha-1 of p2o5, 100 kg ha-1 of k2O and 40 kg ha-1 of n. All treatments were applied to the predecessor crop (corn harvest). The analyzes of variance were not significant for the yield components or the protein content of the grain, however the beans showed a higher average productivity in the treatment with a dose of 9 t ha-1 of poultry litter.
