Effect of P over the yielding and extraction of NP of cultivated bean in three soils.

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.

Efecto del P sobre el rendimiento y extracción del NP de frijol cultivado en tres suelos.

En condiciones controladas, empleando tres suelos Ferralítico Rojo (Eutric ferrasols) con contenido bajo, medio y alto de P disponible, se estudió el efecto que sobre la producción de materia seca y extracción de N y P por plantas de frijol (Phaseolus vulgaris), producía la adición de dósis crecientes de P, entre 0 y 280 kg P2O5/ha, con fondos fijo de 60 kg K2O/ha y 40 kg N/ha e inoculación con bacterias del género Rhizobium. Hubo respuesta vegetal diferenciada, acorde al abastecimiento en P de los suelos. En el suelo de bajo contenido de P, hubo respuesta positiva en los tres índices evaluados, mientras que en los dos suelos restantes, las mayores disponibilidades de P condicionaron una respuesta menor o negativa. Se discute la relación funcional existente encontrada entre los índices evaluados.
