Resumo

The objective of this study was to evaluate the biometric parameters and leaf nutrient content of common bean (Phaseolus vulgaris L.) grown in succession to cover crops, as a function of the application of remineralizer doses (basalt powder) and vinasse. The experiment was conducted in a greenhouse in the experimental design of ran­domized blocks in a 4x4x2 factorial scheme, with three replications. The first factor was remineralizer doses (0, 2, 4, and 8 t ha-1 basalt powder). The treatments with no cover crops (control) and with the cover crops crotalaria (Crotalaria juncea L.), millet (Pennisetum glaucum L.), and brachiaria (Urochloa cv. ruziziensis) constituted the second factor. The third factor corresponded to the presence or absence of vinasse (200 m3 ha-1, and 0 m3 ha-1, respectively). Plant height, shoot dry matter (SDM), leaf area index (LAI), Falker chlorophyll index (FCI), and leaf macronutrient content (N, P, K, Ca, Mg, and S) were evaluated. The association of cover crops, vinasse and remineralizer increased plant height and leaf contents of K, Ca, Mg, and S at the evaluated stage, but vinasse had a positive effect only on S content. Remineralizer doses associated with cover crops provided satisfactory levels of leaf macronutrients for common bean.
