Effect of Integrated Weed Management on the Yield Performance of Wheat

Abstract

The objectives of this study were to determine the influence and comparative efficiency of different weed management practices under integrated weed management of wheat. The experiment comprised three replication group which composed of fourteen weeding regime treatments, namely, unwedded, Mulching by rice straw, Mulching by water hyacinth , Two hand weeding at 25 and 35 DAS, Pre-emergence herbicide, Pre-emergence herbicide + hand weeding at 35 DAS, Pre-emergence herbicide + mulching by water hyacinth, Post-emergence herbicide, Stale seed bed + post-emergence herbicide, Post-emergence herbicide + hand weeding at 35 DAS, Post-emergence herbicide + mulching by rice straw, Post-emergence herbicide + mulching by water hyacinth, Pre-emergence herbicide + Post-emergence herbicide, Pre-emergence herbicide + Post-emergence herbicide + hand weeding at 35 DAS. The experiment was laid out in a randomized complete block design. Data on different parameters were recorded. Most of the yield contributing characters significantly higher at post-emergence herbicide + mulching by rice straw. Among different weeding regime treatments, the highest grain yield (6.92 t ha-1) of post-emergence herbicide + mulching by rice straw compared to unwedded treatment. This result indicates that post-emergence herbicide + mulching by rice straw regime gave higher yield in Agronomy Field Laboratory at BAU.
