Abstract:
A field experiment was conducted to assess the integrated weed management practices in barnyard millet under irrigated condition during Summer, 2021 at Tamil Nadu Agricultural University, Coimbatore. There were ten treatments and replicated thrice in a Randomized Block Design (RBD). The treatments comprised of two herbicides (Pendimethalin and Bensulfuron + Pretilachlor) with or without hand weeding and mechanical weeding. Weed flora observed in experimental field consists of Cynodon dactylon, Dactyloctenium aegyptium, Echinochloa colona under grasses, Cyperus rotundus under sedge and Datura stramonium, Trianthema portulacastrum, Parthenium hysterophorus, Amaranthus viridis, Portulaca oleracea, Digera arvensis and Desmanthus virgatus under broad leaved weeds. Significantly lower total weed density (4.05, 3.03 and 4.03 No. m^-2), weed dry weight (2.94, 2.69 and 4.87 g m^-2) and weed index (2.66%) were lower and higher weed control efficiency (91.64, 97.24 and 91.11%) was observed with PE Bensulfuron methyl 0.6 G + Pretilachlor 6 G 495 g a.i. ha^-1 on 3 DAS followed by one hand weeding on 20 DAS.
