Residual Effect of Nitrogen Fertilization on Nitrous Oxide Flux and Yield of Three Cowpea Varieties (Vigna unguiculata L.) in Rainfed Rice Fields
Wihardjaka, Anicetus
Nitrogen fertilizer use in rainfed rice fields is generally less efficient, only part of N is taken up by plants for their gowth and other N is lost and fixed by soil particles. Nitrogen loss in the form of nitrous oxide can reduce N fertilizer use efficiency and contribute to the increase of atmosp...
