Abstract
The rice-wheat cropping system is believed to cause a considerable depletion of soil nutrients and thereafter long-term productivity is threatening as both the crops in the system are exhaustive in nature. In such a situation, green manuring had an imperative role towards improving crop productivity along with maintaining soil fertility. Green manuring with dhaincha, sunhemp, and mungbean after the harvest of wheat crop in summer months and consequently incorporated into the soil that add organic matter, nitrogen, and other essential plant nutrients. In addition, these crops are able to fix atmospheric nitrogen and thus contribute to nitrogen needs of the subsequent crop i.e. rice.
