Abstract


A field experiment was conducted during 2017-18 at Centre for Hi-tech Horticulture and Precision Farming, Vellanikkara, Thrissur to assess the efficacy of different weed management technologies involving both chemical and non-chemical methods in cabbage. The experiment was laid out in randomized block design with eight treatments and three replications. Among the different treatments, mulching with silver-black polythene alone maintained a weed free condition and resulted in superior yield characters such as head length, head breadth and gross and net head weight. Yield of 16.83 t/ha could be realized under polythene mulching. Pre emergence application of pendimethalin 1.5 kg ha-1 plus manual weeding at 30 DAP gave the next best result in terms of yield and weed control efficiency. Stale seed bed followed by glyphosate application plus manual weeding at 30 DAP, hand weeding twice at 25 and 50 DAP and pre emergence application of oxyfluorfen 0.2 kg ha-1 plus manual weeding at 30 DAP gave comparable per hectare yields of 8.53, 7.90 and 7.44 tonnes respectively. High density planting plus manual weeding at 30 DAP and coconut frond mulching gave lower yields as a result of lower weed control efficiency.
