Extensive efforts have been made to capitalize on the symbiotic relationship of legumes and Rhizabium bacteria by farmers worldwide. These benefits are even more important to farmers in tropical areas where nitrogen fertilizer is expensive. Our objective was to evaluate the effectiveness of the symbiotic relationship of the legumes, pigeonpea, (Cajanus cajan) and kidney bean,(Phaseolus vulgaris) inoculated with Rhizabium selected from Antiguan soils. Undisturbed soil cores measuring 25 cm in length by 10 cm in diameter were used for initial Rhizabium isolation. Surface sterilized seeds of the pigeonpea cultivar, Chaguaramas Pearl were inoculated with the Rhizabium isolated from the soil cores and grown in growth pouches in a growth chamber. Greenhouse and growth chamber studies were arranged as a completely randomized design. Plants grown in undisturbed cores had dry matter yield ranging from l.4 to 0.7 gm per plant and showed significant nodulation. Nodule number from plants grown in pouches ranged from 35 - 120 per plant. A Rhizabium strain isolated from undisturbed core samples was identified as specific to Phaseolus vulgaris.
