SUMMARY

The present experiment was conducted at Seed Research Area, Department of Vegetable Science, CCS Haryana Agricultural University, Hisar (Haryana) in rainy seasons during 2017-18 and 2018-19. The objective of the investigation was to study the effect of nipping and plant spacing on growth, seed yield and quality parameters of cowpea. The experiment was comprised four treatments of nipping (no nipping, nipping at initiation of tendril, nipping at one week after initiation of tendril, nipping at two weeks after initiation of tendril formation stages) and four spacings (60×20 cm, 45x20cm, 30×20 cm and 30×30 cm) was laid out in Randomized Block Design with three replications. Among all treatments, nipping at initiation of tendril formation stage with spacing of 60×20 cm significantly enhance all growth, yield and quality parameters of cowpea seed crop (except plant height) and followed by nipping at one week after initiation of tendril formation stage with spacing of 45×20 cm.

Key words: Cowpea, nipping, spacing, tendril, seed production
