A field experiment was conducted at Rajasthan College of Agriculture, Udaipur to study the effect of sowing time (25 June and 2, 9 and 16 July), plant density levels (3.33 and 4.44 lakhs/ha) and fertility levels (10 + 20, 20 + 40 and 30 + 60 kg N + P2O5/ha) on growth, yield attributes and yield of clusterbean. The crop sown on 25 June resulted in higher plant height, branches/plant, pods/plant, 1000-seed weight and yield which got reduced significantly with delay in sowing ie 9 and 16 July sowings. The magnitude of reduction in seed was 12.8 and 16.0 and haulms yield was 13.4 and 18.0 per cent. The difference in yield attributes and yield produced under 25 June-2 July and 9–16 July was not significant. The plant density had no significant effect on yield of clusterbean. Crop fertilized with 30 kg N + 60 kg P2O5/ha produced higher value in terms of seed yield by 5.2 and 14.0, haulms yield by 6.5 and 16.5 and biological yield by 6.1 and 15.8 per cent as compared to application of 20 kg N + 40 kg P2O5/ha and 10 kg N + 20 kg P2O5/ha respectively.
