FEIJÃO COMUM IRRIGADO E FERTILIZADO COM VINHAÇA

Abstract

The irrigation technique, if used properly, contributes significantly to ensuring a satisfactory yield of the bean crop. The objective of this study was to evaluate the height of bean plants fertigated with vinasse in the first and second harvests submitted to rainfed and irrigated water regimes. The soil in the experimental area is classified as Dystroferric Red Latosol (LVdf), typical, medium texture, cerrado phase. The experimental design used was randomized blocks, analyzed in a 4 × 2 × 2 sub-subdivided plot, with three replications. The treatments consisted of four doses of vinasse (0, 100, 200 and 300 m³ ha^-1); and two water regimes (irrigated and rainfed) and two harvests (first and second harvest). Fertirrigation with vinasse was carried out 50% of the dose before planting and the other 50%, according to the treatments, 50 days after planting; bean seeds of the cultivar BRS Estilo were used. The morphological characteristics were analyzed, in the central lines of each plot, quantifying: plant height. Irrigated beans in the first harvest showed a maximum plant height of approximately 86.81 cm at a dose of 214.66 m³ ha^-1 of vinasse.
