Biometria e fitoproteção de feijão carioca Phaseolus Vulgaris L. submetido à ação trofobiótica de biofertilizante líquido

This study aimed to evaluate the fermented cattle manure biofertilizer’s trophobiotic actionon the biological parameters of growth and plant protection to pests attack of Carioca beanPhaseolus vulgaris L. Plant growth characteristics and number of leaves damaged by phytophageswere evaluated. The treatments were composed of leaf sprays of 5% liquid biofertilizerand only water as control, in 20 replicates, in duplicates of two plants each, in a randomizedexperimental design. The experiment was installed in a mandala production system with doublerow spacing at a density of 50,000 plants / ha. The biometric data obtained with the studiedvariables were submitted to regression analysis, the averages were submitted to analysis ofvariance and compared to Student’s t-test (p <0.05). The biofertilizer demonstrates bioprotectiveeffects, increases the diameter of stem and reduces damages by attack of Agrotis ipsilon,Diabrotica speciosa and Neomegatomus parvus in bean cv. Carioca.
