Abstract
Abstract The objective of this work was to quantify the extraction and export of nutrients by common bean (Phaseolus vulgaris) cultivars from different commercial groups and with different growth habits. The experiment was conducted using four common bean cultivars: TAA Gol, BRS FC104, IPR Tuiuiú, and TAA Dama. Total dry matter (DM) and nutrient accumulation in the V4 (with four, six, and eight three-leaflet leaves), R5, R7, R8, and R9 stages was determined, as well as grain yield and nutrient export. Differences were observed both in nutrient uptake and in DM and nutrient accumulation among the cultivars in the initial stages of development (V4 with six and eight three-leaflet leaves). The TAA Gol cultivar showed a greater accumulation of almost all nutrients in these two initial stages. In R7, the cultivar that had the greatest DM and nutrient accumulation was TAA Dama, but, from R8 onwards, there were no significant differences. Although nutrient export is similar among the evaluated cultivars, a lower percentage is translocated to the grain in TAA Dama.
