Produção de feijão-caupi em função do emprego de inoculante e adubos orgânicos e mineral

Abstract

ABSTRACT: Cowpea is a widely cultivated legume, especially in northeastern Brazil. In its cultivation, it is generally employed high solubility mineral fertilizers that can cause numerous environmental impacts, and considerably raise production costs. Thus, cultivation practices that may decrease the use of mineral fertilizers should be studied and validated. Thus, the objective of this work was to evaluate vegetative and productive components of cowpea submitted to different organic, inoculant and mineral fertilizers. The treatments were distributed in randomized blocks, with nine treatments and three repetitions: Witness (T), without fertilization; biofertilizer (B); inoculant (I); milk residue (R); biofertilizer + inoculant (BI); dairy residue + biofertilizer (RB); milk residue + inoculant (RI); milk residue + inoculant + biofertilizer (RIB) and the formulated NPK (M). Organic fertilizers and inoculant alone or associated do not contribute to cowpea productivity. The use of mineral fertilization increased cowpea productivity.
