EFFECT OF HERBICIDES ON WEED CONTROL EFFICIENCY ANDYIELD RESPONSE OF KHARIF COWPEA (VIGNA UNGUICULATAL.) IN SANDY LOAM SOILS OF PUNJABP.J. Khose1*, L.S. Vyvahare1, S. Menon1, K. Yadav2, B.R. Divyavani3 and S. Patil2Abstract A field experiment using a randomized block design, eight weed management treatments, and threereplications was carried out in the kharif of 2022 at the Division of Agriculture, Lovely Professional University,Phagwara, Punjab, India. To determine the economics and effectiveness of weed control measures formanaging weeds in cowpea [Vigna unguiculata (L.). The weed control techniques had a big impact on theweed restrictions.With pre-emergence application (PE) of pendimethalin 0.70 kg/ha combined with handweeding, the weed density and biomass and greater weed control efficiency were consistently inferior atdifferent stages of crop growth. This confirmed that pre-emergence herbicide application could effectivelyregulate the weeds emerging early in the season, and the actual controlling of weeds by it led tohigher yield and B: C ratio. |
