Abstract:
The cabbage head yield is reduced due to infestation of weeds at all the growth stages. To reduce the weed density in crop field by using different weed management practices, based on this a field experiment was conducted during rabi season 2016-2017 at College of Horticulture, Bidar, Karnataka, Indiato study the effect of different weed management practices on growth, yield and economics of cabbage. The treatment consist of T₁ [Pendimethalin 38.7 CS 0.7 kg a.i/ha (PE) +1 HW 30 DAT], T₂[Pendimethalin 30 EC 1.5 kg a.i/ha (PE)+1 HW 30 DAT], T₃ [Oxyfluorfen 23.5 EC 0.25 kg a.i./ha (PE]+1 HW 30 DAT), T₄ ] Alachlor 50 EC 1.5 ltra. i/ha (PE) +1HW 30 DAT], T₅ [Butachlor 50 EC 1.5 kg a.i/ha (PE) +1 HW 30 DAT], T₆ (HW at 25 and 50 DAT), T₇ (Weed free check) T₈ (Weedy check) were arranged in randomized block design with three replications. The results indicated that the weed free recorded maximum value of plant height (29.62cm), head maturity duration (61.33days) and yield attributing characteristics diameter of head(16.82cm), average head weight(1.63 kg) and head yield(27.78 t/ha). It was followed by Pendimethalin 38.7 CS 0.7 kg a.i/ha (PE)+1 HW 30 DAT, Pendimethalin 30 EC 1.5 kg a.i/ha (PE)+1 HW 30 DAT, HW at 25 & 50 DAT. Maximum weed population (4.44), weed dry weight (1.08g) and weed index (70.69) was recorded with the treatment weedy check. Highest weed control efficiency (100%) was recorded with weed free. Maximum gross return (Rs.128514), net return (Rs.88496) was obtained with Pendimethalin 38.7 CS 0.7 kg a.i/ha (PE) +1 HW 30 DAT compared to rest of treatments. The application of Pendimethalin 38.7 CS 0.7 kg a.i/ha (PE) +1 HW 30 DAT was found better compared to rest of the treatments.
