Abstract

Weed management is critical to obtaining profitable yields in minimum tillage system. Innovative weed control strategies including chemical methods will continue to be an essential component in the development of sustainable conservation agriculture (CA) practices (Andrew and Kelton, 2011). Weed management in minimum tillage relied on extensive use of herbicides. This may leads to the development of resistance in weeds. Crop residue can decrease density and dry weight of perennial weeds by 35 and 75%, respectively, and of annual weeds around 80% compared to no residue (Fisk et al., 2001). Wheat (Triticum aestivum L.) residue can reduce weed seedling emergence in corn by 45% (Crutchfield et al., 1986) and weed biomass in sorghum (Sorghum bicolor L.) by 60% (Wicks et al., 1994). These results suggest that, residue retention can be a promising method providing a sustainable approach for suppressing weeds in conservation tillage. Therefore, a study was undertaken to examine, weeds management and yield performance of mustard under minimum tillage and different levels of residue retention.
