The benefits of tillage are multifaceted as it loosens soil, enhance release of nutrients from soil for plant growth, kill weeds and regulates the circulation of water and air through soil which lead to an enhanced nutrient uptake and better yield of crops. Weeds creating competition for nutrients, space, water etc. reduce the crop yield and deteriorate the quality of produce hence, reduce the market value of the turnout (Arif et al. 2006). The response of weed flora to different weed control methods also vary depending upon field situation. Tillage affects the weeds by uprooting, dismembering and burying them deep enough to prevent emergence by changing soil environment and so inhibiting weeds germination and establishment, thereby creating favorable soil environment for plant growth (Sawanton et al. 2000). Soybean is a miracle crop which is mainly grown for oil and is a good source of protein, used in cattle feeds. Weed infestation in soybean results in a loss of yields to the extent of 30-80 per cent (Yaduraju et al. 2002). Hence, an experiment was conducted to identify ideal method of weed management in soybean-wheat cropping system.
