An experiment was conducted during 1995 and 1996 to study the influence of seed pelleting with diammonium phosphate (DAP) and potassium dihydrogen phosphate (KH,PO,) in comparison with DAP spray in rainfed Paiyur 1 cowpea [Vigna unguiculata (L.) Walp.] under North Western Agroclimatic Zone of Tamil . Nadu. Soil application of recommended inorganic fertilizers (RIF) 2% DAP spray twice (first at flowering and second at 15 days after first spray) showed the highest plant height. Branches and podslplant, seedslpod, 100 seed weight, dry matter production, seed yield, net income and benefit : cost ratio. Seed pelleting with DAP and KH,PO, did not influence the above said parameters appreciably.References
