Incidence of disease in cowpea submitted to different biofertilizer dosages

Abstract

The use of liquid biofertilizer is a sustainable alternative for agricultural use, as it is a technique that consists of the use of food waste that is biodegradable by microorganisms, providing food for use in agricultural crops. It can be a viable alternative to cowpea production, providing useful nutrients for this crop, as well as providing disease and insect inhibition. Therefore, the objective of this study was to evaluate the incidence of cowpea disease submitted to different doses of biofertilizer. The experiment was carried out at the Federal University of Western Pará, conducted in a randomized block design with five replications. The procedures were 4 doses of biofertilizer (50, 100, 150 and 200 ml plant -1) and mineral fertilization as a function of soil analysis. Disease data were used in the binary matrix of disease presence and absence and subsequently analyzed by the 5% probability TCL test. The test did not show significance for diseases with mineral fertilization with p> 5%, such as 50 and 200 ml doses of plant -1 also with higher incidence of diseases p> 5%. The doses of biofertilizer that presented significance and the lowest incidence of diseases in cowpea were the doses of 100 and 150 ml plant -1 with p <5% and presented 9% of disease incidence. The use of soil-applied liquid biofertilizer inhibited the incidence of cowpea diseases
