We investigated biomass and protein productivity of Sudan sorghum and maize crops in relation to nitrogen fertilization (6, 15 and 35 g m­2) in central Greece. Sudan sorghum was cultivated under two management techniques: (a) as a row crop similar to maize cultivation (row­to­row distance: 75 cm; observed shoot density: 27 per m2) with a single harvest per year; and (b) as a very dense crop (row­to­row distance: 10 cm; observed shoot density: 155 per...
