COINOCULAÇÃO Azospirillum brasilense E Rhizobium tropici NO DESEMPENHO PRODUTIVO DE FEIJÃO-COMUM PRETO CULTIVADA EM TOMÉ-AÇU, PARÁ.

Abstract

The common bean (Phaseolus vulgaris L.) is an agricultural crop of great relevance in environmental, social and economic aspects, because in addition to presenting characteristics of symbiosis with microorganisms, it is a main constituent in human food and contributes to income generation for small, medium and large farmers. The objective of this work was to evaluate the biometric and productive characteristics of common bean BRS Esteio submitted to inoculation with Azospirillum brasilense and Rhizobium tropici associated with nitrogen fertilization in Amazonian soil. The experiment was carried out in the experimental area of the Associação dos Agricultores do Vale do Acará (AAVA), with an experimental area measuring 10m x 10 m, subdivided into 16 plots of 2m x 2m each, located in the municipality of Tomé-Açu, Northeast of Brazil. For. The design was completely randomized. The treatments used were: control without inoculant and nitrogen fertilization, inoculant only, inoculant plus nitrogen fertilization, nitrogen fertilization only, with four replications. It was noted that there was no significant difference between treatments for the variables; Insertion height of first Pod and Grains per Pod. The treatment, inoculant and nitrogen fertilization, delivered the highest plant heights, in all evaluations.
