Cover Story: Inside our research regarding split nitrogen application regimes, we found that nitrogen-use efficiency, radiation-use efficiency, grain yield, and biomass of C3 winter (wheat, oats, and barley) and C4 summer (maize, millet, and sorghum) cereals can be increased through higher nitrogen availability/uptake and minimizing losses like denitrification, leaching, runoff, and volatilization under irrigated conditions in an arid environment. Our study results highlight that nitrogen application in three splits augmented productivity and resource-use efficiency in C3 and C4 cereals. View this paper
