Effect of P over the yielding and extraction of NP of cultivated bean in three soils.
Under controlled conditions and utilizing three soils of Red Ferralithic (Eutric Ferrasols) type with low, medium and high available P we studied the effect over the production of dry matter and the extraction of N and P performed by the bean plant (Phaseolus vulgaris L.), produced by the addition in increasing dosage of P, between 0 and 280 kg P2O5/ha, with fixed basis of 60 kg K2O/ha and 40kg N/ha and inoculation with bacteria from the Rhizobium genera. The experimental results showed a plant response differentiated by the availability of P in the soil. In soils with low P contents there was a positive response in the three evaluated indexes, while in the other two soil samples the higher availability of P produced a smaller or negative response. We also discuss the functional relationship found among the evaluated indexes.
