Abstract
A field experiment was conducted during Rabi, 2018-19 at Horticulture farm, RAK College of Agriculture, Sehore (M.P.) to study the effect of different weed management practices on growth and yield of cauliflower. The treatments namely - T1- Weedy check (control), T2- Weed free (through hand weeding) at 30 & 60 DAT, T3 -Pendimethalin 30% EC (PE) + one hand weeding at 30 DAT, T4 Oxyfluorfen 23.5% EC (PE) + one hand weeding at 30 DAT, T5 - Propaquizafop 10% EC (POE) + one hand weeding at 60 DAT, T6 -Wheat straw mulch 5kg/plot, T7- Black plastic mulch (150 mm) were evaluated in randomized block design with three replications. Results indicated that the there was no weed under T7 -black plastic mulch (150 mm) at all the stages. The maximum weed control efficiency (98%) was found with the treatment T7 - black plastic mulch (150 mm) at all the stages i.e. at 30, 60 and 90 DAT. The minimum weed index (0.00, 0.00 and 0.00%) was found with the treatment T7 (Black plastic mulch (150 mm) at all the stages. The maximum curd length, curd width, total curd weight (g) and curd yield (q ha-1) was recorded T7- black plastic mulch (150 mm) with the maximum net return (Rs. 75772.58 per ha).While the lowest net return was found under T1 (Weedy check) (Rs. 21405.34 per ha) treatment. The maximum B: C ratio (1:4.0) was recorded in case of treatment T3 [Pendimethalin 30% EC (PE) + 1HW at 30 DAT].
