Abstract: A field experiment was carried out during rabi 2021-22 to study the effect of agronomic weed management practices on growth, yield attributes and yield of barley (Hordeum vulgare L.).The experiment was laid out in randomized complete block design with eight treatments replicated thrice. The weed control treatments comprised of weedy check, weed free, weed free for 15, 30 and 45 days and weedy up to 15, 30 and 45 days. The highest weed density (66.6 plants/m²) and weed dry weight (63.0 g/m²) were recorded in weedy check whereas, weed free recorded minimum (0.70 plants/m² and 0.70 g/m² respectively). Weedy check treatments recorded higher weed density and weed dry weight however weed free treatments recorded lower weed density and weed dry weight. Weed free for 15, 30 and 45 days and weedy upto 15 days recorded significantly lower weed index however weedy check for 30 and 45 days recorded higher weed index. The highest grain yield (45.3 q/ha) was recorded in weed free which was significantly higher than weedy check, weedy up to 15, 30 and 45 days (32.0 q/ha, 38.0 q/ha, 36.3 q/ha and 34.7 q/ha respectively) but was at par with rest of the treatments. Similar trend was also observed in growth parameters and yield attributes.
