Effect of different weed management practices on growth and yield of cauliflower (Brassica oleracea var. botrytis L.)

Abstract

A field experiment was conducted during Rabi, 2018-19 at 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) + 1 HW at 30 DAT, T4 Oxyfluorfen 23.5% EC (PE) + 1 HW at 30 DAT, T5 - Propaquizafop 10% EC (POE) + 1 HW 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 T7 -Black plastic mulch (150 mm) recorded maximum value of plant height (cm), stalk length (cm), number of leaves/plant, Leaf area (cm2), Chlorophyll content (SPAD value) and yield attributing characteristics curd length, curd width, average curd weight, curd yield and marketable curd yield (q/ha). It was followed by T2 - weed free (through hand weeding) at 30 & 60 DAT. Maximum plant height, stalk length, number of leaves/plant, Leaf area (cm2) and Chlorophyll content (SPAD), total curd yield (q/ha) and marketable curd yield (q/ha) was recorded with the treatment T7- Black plastic mulch (150 mm).
