Rice-wheat (Oryza sativa aestivum L.) rotation is the major production system in Asia, covering about 18 million ha. Continuous and conventional RWC system practice has witnessed a significant slowdown in the yield growth rate. The sustainability of this important cropping system is at risk due to second-generation problems (low fertility status, multiple nutrient deficiencies, and imbalanced use of fertilizers, ground water depletion at faster rate, soil salinization, and inadequate system diversity). |
