Abstract We determined the (1) deficiency, (2) apropriate level and (3) toxiticity of phosphorus on the total biomass production and yield of judía verde (Phaseolus vulgaris L.) cv. ‘Strike’. Studies were conducted in a growth chamber using pots. Phosphorus levels in the nutrient solution were P1: 0.5 mM; P2: 1 mM; P3: 2 mM; P4: 4 mM; P5: 6 mM, and P6: 8 mM. The optimum phosporus concentration was P3. As soil phosphorus concentration increased, concentration of this nutrient also increased in the plant. Leaf, petiole and shoot biomasses were more sensitive to deficiency than to toxicity of phosphorus. However, root… More >
