Abstract:
A field experiment was conducted at Students’ Instructional Farm of Chandra Shekhar Azad University of Agriculture and Technology Kanpur, Uttar Pradesh to assess the effect of land configuration and weed management practices and their interaction effect on growth of kharif maize for two consecutive years (2018 and 2019). The experiment comprises of three land configuration method as a main treatment viz; P1-flat-bed planting, P2-Ridge and furrow planting and P3-Broad bed and furrow planting and six weed management practices were applied as sub treatment viz; W1 -Pendimethalin @ 1.0 kg ha-1 as pre – emergence + Halosulfuron methyl @ 67.5g ha-1 at 15-20 DAS as post- emergence, W2 -Atrazine @ 1.0 kg ha-1 as pre – emergence + Halosulfuron methyl @ 67.5g ha-1 at 15-20 DAS as post – emergence, W3-Pendimethalin @ 1.0 kg ha-1 as pre- emergence + Halosulfuron methyl @ 67.5g. ha-1 at 15-20 DAS as post – emergence + one hand weeding at 45 DAS, W4-Atrazine @ 1.0 kg ha-1 as pre – emergence + Halosulfuron methyl @ 67.5g ha-1 at 15-20 DAS as post – emergence + one hand weeding at 45 DAS, W5- Weed free and W6 -Weedy check making eighteen treatment combination which was assigned in a Split Plot Design (SPD) replicated thrice. Hybrid maize variety (DKC –7074) was grown with the recommended agronomic practices. Results showed that maximum increase in yield attributing characters viz: number of cob plant-1, cob length (cm.), cob weight (g.), cob girth (cm.), number of grain rows cob-1, number of grains row-1, number of grains cob-1, grain weight cob-1 (g), 100 grain weight (g) and shelling (%) recorded highest with Broad Bed and Furrow Planting method and weed free plots. Significantly highest grain (60.99 q ha-1) and stover yield (116.14 q ha-1) was recorded in broad bed and furrow method of planting as compared to other land configuration methods of planting. Among weed management practices, weed free plot produce significantly maximum grain (65.53 q ha-1) and stover yield (121.46 q ha-1) as compared to all other treatments.
