Abstract: Weed infestation in rice field is always subject to agro ecological condition and growing seasons. Weeds cause major yield losses in crops and also reduce their quality. An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to investigate the efficacy of mustard crop residues on weed management and crop performance of transplant aman rice. The experiment consisted of three cultivars and five different levels of mustard crop residues. The experiment was laid out in a randomized complete block design with three replications. Weed population, weed dry weight and percent inhibition of weed were significantly influenced by mustard crop residues and cultivar. The maximum weed growth was noticed with the cultivar BRRI dhan34 and the minimum was found in the cultivar BRRI dhan49. The grain yield and other yield contributing characters produced by BRRI dhan49 was the highest among the studied varieties. The highest percent inhibition of 73.36, 78.82, 71.90, 76.83 and 81.53 found in Pani kachu, Chechra, Pani shapla, Shama and Sabuj nakful, respectively with the application of mustard crop residues at 3.0 t ha-1 + one hand weeding. It can be concluded that BRRI dhan49 and mustard crop residues showed potentiality to inhibit weed growth and it has a significant effect on the yield of transplant aman rice. Therefore, mustard crop residues could be recommended to use as an alternative tool for weed management.
