Nutritional demand and nutrient export by modern cultivars of common bean

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