Description
Glass house experiments were carried out in the Experimental Station La Renee located in Habana province in the year 2003. The objective of this study was to evaluate the effectiveness of phosphorus (P) sources varying in solubility for common bean (Phaseolus vulgaris L.) nutrition using the isotopic dilution method with 32P, growing under two soils: Acrisol and Rhodic Ferralsol. The P sources, evaluated in both soils were phosphate rock (PR) Trinidad de Guedes and PR partially solubilized at 50% with H2SO4, namely FPA 50, whereas single super phosphate (SS) and triple super phosphate (TSP) were used in the Acrisol and Rhodic Ferralsol Soils, respectively. The common bean genotypes were BAT 477, DOR 364, DOR 390 and Censa, and BAT 58, BAT 477, DOR 364 and CC-25-9(N) in the Acrisol and Rhodic Felrrasol soils, respectively. Dry matter production, P extraction, and the fraction and quantity of P in plants obtained from different P sources were evaluated, and P use efficiency of each P fertilizer were calculated. Single and tripe super phosphate and FPA 50 were effective P fertilizers in both soils whereas RF was not. (author)

Se condujeron experimentos en casa de cristales de la Estacion Experimental La Renee ubicada en la provincia Habana en el ano 2003. El objetivo fue evaluar fuentes fosforicas de diferente solubilidad para frijol comun (Phaseolus vulgaris L.) utilizando dos suelos: Acrisol y Ferralsol rodico, y la tecnica de dilucion isotopica con 32P. Las fuentes fosforicas evaluadas fueron roca fosforica (RF) Trinidad de Guedes, RF parcialmente solubilizada al 50% con H2SO4 (producto denominado comercialmente FPA 50) y superfosfato simple (SS) en el Acrisol y superfosfato triple (SFT) en el Ferralsol rodico. Los genotipos de frijol empleados en el Acrisol fueron BAT 477, DOR 364, DOR 390 y Censa, mientras que en el Ferralsol fueron BAT 58, BAT 477, DOR 364 y CC-25-9 (N). Se evaluo produccion de materia seca y extraccion de P y se determino la fraccion (%) y cantidad de P en planta derivado de los portadores y % de eficiencia de uso del fertilizante. La RF en aplicacion directa fue poco efectiva mientras que los superfosfatos y el FPA 50 resultaron efectivos en ambos suelos. Hubo diferencia varietal en la respuesta vegetal y en la utilizacion del P de las fuentes, que tambien dependio de las caracteristicas del suelo. (autor)Additional details
