Experiments were conducted during rabi seasons of 2003-04 and 2004-05 at Pulses Research Sub-Station, Samba of SKUAST-Jammu on sandy loam soils to evaluate the effect of phosphorus (0,30 and 60 kg P,O/ha) and seed rate (75, 100 and 125 kg/ha) on the productivity of large seeded chickpea ev. BG 1053. Results indicated that seed rate of 100 kg/ha significantly increased seed yield/ha (1012.3 kg/ha) over 75 kg/ha (909.5 kg/ ha) and further increase in seed rate recorded lower seed yield (995.2 kg/ha) due to relatively inferior yield attributes with increase in seed rate. Increasing levels of phosphorus up to 60 kg P,O/ha resulted in significant increase in dry matter accumulation (18.17 g/plant), phosphorus uptake, yield attributes viz., pods/plant, seeds/pod and 1000-seed weight) and seed yield (1145.9 kg/ha). Increased P,O, levels greatly reduced pod damage (16.0%) while increased seed rate from 75 to 100 kg/ha increased Helicoverpa population (22.7% and 30.7% with seed rate of 75 and 125 kg/ha).
