Abstract:

Performance of irrigation time and weed management practices against weeds in wheat was evaluated. Chenopodium album L. and Chenopodium murale L. were predominating weed species and comprised about 76% of total weed population in weedy check. Pre-sowing irrigation reduced the dry weight of C. album and C. murale by 21 and 25%, respectively, and subsequently grain yield was 12% higher over post-sowing irrigation. Pre-emergence application of pendim~thalin at 0.75 kg ha" supplemented by one hand weeding or 2, 4-D, 0.50 kg ha" at 30 DAS gave significantly higher grain yield due to better weed control. However, the higher additional net return (Rs. 8063) was also obtained with pendimethalin at 0.75 kg ha"+one hand weeding.
