RESPOSTA DO FEIJÃO MACASSAR E COMUM À INOCULAÇÃO COM RIZÓBIO E USO DE BIOFERTILIZANTE EM UM AGROSSISTEMA FAMILIAR

Abstract

The objective of this work was to verify the effect of inoculation with rhizobium and application of organic fertilization on the Cowpea Bean (Vigna unguiculata (L.) Walp.) And Common Bean (Phaseolus vulgaris L.). The experiment was carried out in the Sítio Mãe Rosa property, in the municipality of Remígio, in the state of Paraíba, between May and July 2017. The experimental design was a randomized block design consisting of four treatments, three replications and two cultures, totaling 24 experimental units. The treatments, in common for the two cultures, consisted of: T0 (control); T1 (rhizobium inoculation); T2 (application of biofertilizer) and T3 (inoculation with rhizobium + application of biofertilizer). The height of plants were evaluated; Stem diameter; Number and dry mass of nodules; Dry mass and nitrogen accumulated in the aerial part. The data were submitted to analysis of variance and the means were compared by the Tukey test, at 5% probability. In the common bean, the use of the biofertilizer and the inoculation with rhizobia presented significant differences for most of the evaluated characteristics, on the other hand there was no difference between them, as well as in the interaction of both, similar behavior was seen in macassar bean culture. In short, the two species had a large part of their vegetative characteristics positively influenced by the use of treatments, biofertilizer application and inoculation with rhizobium, respectively, evidencing the importance of the use of these media as an alternative for sustainable food production.
