How the nitrogen fertilization dose affects the biochemical composition and net mineralization of the artichoke residues

In Egypt, recycling of vegetable and crop residues is improving of environmental and efficiency of nitrogen use. In this study, artichoke (Cynara cardunculus L.) plants have been grown in field for nine months at three rates of nitrogen fertilization: 0 (N0), 250 (N250), 500 (N500) kg ha-1. The aims...
