The experiment was carried out under green house conditions using 1000 cc pot hidroponic thechniques; it was oxigenated with 400 ml.l-1.minutes-1, where common bean plants arranged in randomized block design. The effect of 0; 0.25; 0.50; 0.75 and 1.00 mm of phosphorus concentration over the biomass developed by leafs, leafstalks, stalks, roots, pods; total biomass; the total plant phosphorus concentration and the phosphorus use efficiency shown the common bean variations (Phaseolus vulgaris L.) such as CC25-9(N), BAT 58 and BAT 304, were studied. There was found significative difference between the amount of biomass formed by leaf, stalk, pods and, the total plant biomass; the total plant phosphorus concentration changed in order of the phosphorus solution concentration used; while the phosphorus use efficien reached the uppermost value at 0.50 mm of phosphorus concentration. There is specific phosphorus incidence over the nutrition of bean genotype. The results showed that the different bean genotypes have different phosphorus requirements.
