Fig. (2) Scheme representing the importance of using pea or faba bean pod shells ‘after seed removals’ as green manure in N fertilizer saving and in percent increments of dry matter, N and P uptake of different plant parts of sorghum, as compared with the un-manured control treatment. Data represents the lowest and the highest value of increments according to applied N in the form of GM. The lowest values belonged to N50 treatments that were higher in PGM than FGM. The highest values belonged either to N100 or to N150.
