Pueraria phaseoloides, Mucuna bracteata and Calapogonium caeruleum were studied in a pot culture experiment using graded doses of rockphosphate. The cover crops responded to phosphorus application irrespective of the species. Among these species, varied responses were noted by the application of graded doses of phosphorus. Six months after planting, Pueraria showed superiority over other two species while Mucuna and Calapogonium were found to be on par in both dry matter production and uptake of nutrients. Dry matter production under both 30 and 45 kg P2O5 per ha application was on par ER -
