Growth and phosphorus absorption by common bean 'Xodó' genotype under effect of glyphosate reduced rates

Abstract

It was evaluated the effect of glyphosate reduced rates on growth and phosphorus (P) uptake of ‘Xodó’ common bean (Phaseolus vulgaris L.) genotype. The experiment was conducted in factorial scheme 4 x 2, in randomized blocks design with four replications, with the first factor constituted by reduced doses of 0, 4.32, 8.64 and 12.96 g ha^-1 equivalent acid (e.a.) of glyphosate and the second factor consisted of soil P rates (50 and 250 mg dm^-3). Evaluations were conducted 30 days after glyphosate application (DAA). The reduced dose of 12.96 g ha^-1 stimulated common bean cv. Xodó growth as well as increased P concentration in stem and P content in shoot dry mass plants.
