Resource conserving technologies (RCTs) enhance input use efficiency and provide immediate identifiable and demonstrate economic benefits such as reduction of production costs, savings in water, fuel and labor requirements and timely establishment of crops resulting in improve yields. Rice is transplanted in flat fields that are typically ponded for long periods that negatively affect soil properties for the non-puddled crop (Kumar et al. 2000). Wheat is then planted in structurally disturbed soils, often after many tillage operations to prepare the seedbed. Growing crops on the raised beds offers more effective control of irrigation water and drainage management. Permanent raised beds might offer significant advantages for crop yields and be further increased by using residue retention (Sayre et al. 2005). Yields of rice and wheat in heat and water-stressed environments can be raised significantly by adopting RCTs, which minimize unfavorable environmental impacts, especially in small and medium-scale farms. Inclusion of grain legumes in rice-wheat cropping system may be another option for increasing cropping intensity, soil fertility and productivity. Limon-Ortega et al. (2000) observed that permanent beds with straw retention had the highest wheat grain yields with positive implications for soil health. Thus, crop residue management along raised bed strategies, are likely to be key components of increase crop productivity and soil fertility in rice-wheat system.
