Summary
This work evaluates the effects of growing a green manure crop or a legume crop in winter wheat yield and on nitrate leaching, in an irrigated crop rotation. Results are also compared with a conventional cropping system. Simulations with the field version of the FASSET model (Berntsen et al., 2003) were done to evaluate the performance of the model to predict winter wheat dry matter yield. The simulated leaching from the different cropping systems was evaluated during the rotation period.
