SUMMARY
A field experiment was planned to evaluate the performance of herbicides for weed control in cowpea cultivars during Kharif season 2018-19 to 2020-21 at the Research Farm of Vegetable Science, CCS Haryana Agricultural University, Hisar, India. Three years data (2018-19 to 2020-21) on weed management in cowpea cv P-263 revealed that the pre-emergence application of pendimethalin @ 6 ml/L+ One hand weeding 25 DAS (T4) resulted maximum green pod yield of 80.5 q/ha with maximum B:C ratio of 2.2 excluding fruit yield of 84.6 q/ha under weed free check (T2). However, these both treatments (T2 and T4) were statistically at par in terms of pod yield/ ha. Although, the weed free check (2-3 hand weeding) (T2) recorded highest pod yield but the net return of this treatment is less (B:C ratio 1.3) due to higher cost of cultivation.
