Integrated Weed Management in Pea (Pisum sativum L.) under Sangla Valley Conditions of Himachal Pradesh

Pendimethalin and fluchloralin were the most effective herbicides in controlling weeds in pea. Pendimethalin at 1.50 kg ha−1 and fluchloralin at 1.00 kg ha−1 remaining at par, increased pods plant−1, seeds pods−1 and yield significantly. Superimposition of hand weeding over pendimethalin and fluchloralin did not record any significant benefit in terms of yield. Alachlor at 1.50 kg ha−1 and metolachlor at 1.50 kg ha−1 were not 6ffective against broad-leaved weeds. Fluchloralin at 1.00 kg ha−1 resulted in maximum marginal benefit: cost ratio (MBCR, Rs. 17.18) followed by fluchloralin at 1.00 kg ha−1+ hand weeding and pendimethalin at 1.50 kg ha−1.
