A field experiment was conducted during kharif 2023 and 2024 to study the influence of nutrient levels and weed management practices on weed control efficiency in aerobic rice. The experiment consisted of three nutrient levels viz., 75:37.5:37.5 kg N:P2O5:K2O ha-1, 100:50:50 kg N:P2O5:K2O ha-1 and 125:62.5:62.5 kg N:P2O5:K2O ha-1 along with four weed management practices viz., hand weeding + intercultivation at 20 and 40 DAS, pyrazosulfuron ethyl 10% WP @ 100 g ha-1 (PE) + sunhemp, pyrazosulfuron ethyl 10% WP @ 100 g ha-1 (PE) + bispyribac sodium 10 SL @ 0.4 ml L-1 (POE) and weedy check. The experiment was laid out in factorial randomized block design with three replications. Among nutrient levels, higher weed control efficiency was recorded under application of 125:62.5:62.5 kg N:P2O5:K2O ha-1 with pooled values of 59.5 per cent at 45 DAS and 59.3 per cent at 60 DAS. Among weed management practices, hand weeding + intercultivation at 20 and 40 DAS recorded the highest pooled weed control efficiency of 89.3 per cent at 45 DAS and 82.7 per cent at 60 DAS.
