| 520 | _aThe rice-wheat cropping system is the most important cropping system in the northern tropics of Asia, with an estimated area of 21.9 million ha in seven countries. Wheat cultivation has recently expanded to Southeast Asia, where it could become a significant crop in the postrice season. Rice and wheat yields are stagnant or even declining in some major producing areas. Continuous cereal cropping has depleted inherent soil fertility and deficiencies of important plant nutrients have appeared. Organic manures, especially green manures (GMs) are a potentially feasible means of improving soil fertility and physical properties. However, the high cost of land preparation and labor and the constraints associated with fitting sole-crop GMs into increasingly intensive cropping systems limit their use. This paper reviews the current status of GM production in rice-wheat systems. It analyzes the promising concept of interseeding a noncompetitive legume with wheat, based on research with Indigofera tinctoria. It evaluates the basis for expanding GM use in the future | ||
