An experiment was conducted during 1995 and 1996 to study the influence of
seed pelleting with diammonium phosphate (DAP) and potassium dihydrogen pho
sphate (KH2PO4) in comparison with DAP spray in rainfed Paiyur 1' cowpea [V
igna 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) s
howed the highest plant height. Branches and pods/plant, seeds/pod, 100-see
d weight, dry-matter production, seed yield, net income and benefit : cost
ratio. Seed pelleting with DAP and KH2PO4 did not influence the above-said
parameters appreciably.
