Mineral nitrogen fertilization and stover management effects on maize production under irrigated mediterranean conditions. Simulation of yields

The optimal N application rates were investigated with the effects of stover management on maize production and its possible interaction with N fertilization. A field experiment was conducted from 2010 to 2014. The rates of mineral N fertilization applied were: 0, 100, 200 and 300 kg N ha-1 year-1....
