In conservation agriculture crop rotations, mulching, use of cover crops and good crop husbandry are very useful measures. Chemical control of weeds creates environmental hazards and residual effects on crops. Weed management through mulches may be alternative to chemical weed control. Organic weed management through application of different mulches can suppress the weed growth as well as improve soil fertility. The present review describes the role of mulches in improving crop yield, weed control, soil water conservation, physical and chemical properties of soil.
