The present investigation was carried out at the Research farm of Abhilashi University, Mandi (H.P) during the kharif season of 2023. Seven different treatments were evaluated in a randomized block design with three replications. The main objectives of the investigation were to assess the impact of different weed management practices on growth and yield of cabbage crop. The results revealed that treatment T7 (Weed-free) recorded the maximum values of all parameters viz., plant height (32.23 cm), number of unwrapped leaves (15.49), dry weight of unwrapped leaves (26.59 g), dry weight of wrapped leaves (115.58 g), head weight (958.16 g), yield per plot (17.25 kg) and yield per hectare (344.94 q/ha) due to less presence of weeds and lower weed competition. Major weeds that were observed in the experimental field were Eleusine indica L., Trifolium fragiferum L., Stachys arvensis L., Galinsoga quadriradiata L., Lysimachia arvensis L., etc. Minimum values of weed parameters viz., weed count (0.00), weed fresh weight (0.00 g) and weed dry weight (0.00 g) were recorded in treatment T7 (Weed-free) while highest weed control efficiency (100%) was recorded under the same treatment. In terms of economics, the maximum cost of cultivation (₹ 1,34,930) and gross income (₹ 5,20,106) was recorded under treatment T7 (Weed-free) while the net income (₹ 3,84,986) and B: C ratio (3.89) was recorded highest under the treatment T3 (Oxyfluorfen 0.25 kg/ha + HW at 30 DAT) which is combined application of herbicides and manual weeding.
