Conteúdo: 	This work aimed to study the biomass production and nutrient uptake during plant development and nutrients exported by the grains of a super early genotype (SEG) of common bean. The irrigated field experiment was done during the 2016 growing season (winter season), under no-tillage system conditions, in the Cerrado region. Experimental design was in complete randomized block in split plots scheme, with four replications. Main plots comprised SEG of common bean (Colibri ? check cultivar and CNFC 15874) and subplots were nine times of plant collection (14, 21, 28, 35, 42, 49, 56, 63 and 70 days after plant sowing, DAS) with separation in leaves, stem and pods. Absorption of nutrients by the shoots of SEG CNFC 15874 follows the decreasing order N> K> Ca> Mg> P> S> Fe> Zn >Mn >Cu. The maximum accumulation of nutrients in the leaves and stem of the SEG was at 42 DAS (full flowering stage) and in the pods between 63 to 70 DAS (physiological maturation). Nitrogen, K, P, Ca, S, Fe, Zn, Mn and Cu was the order of accumulated nutrients in grains of super early genotypes. Nitrogen, P and Cu was the nutrients with higher amount in the grains of SEG. IPR Colibri had higher number of pods, mass of grains, total and pods biomass production, nutrients accumulation and grain yield than CNFC 15874. Nutrients should be available to SEG of common bean between 14-21 DAS (third trifoliolate leaf).
