Abstract
- Field experiments were carried out in Central Italy on several green manure species (pure or mixed) and on succeeding grain maize to find practical relationships for predicting the N effect (N absorbed by maize that derives from the actual gain in soil available N due to green manure). Actually, little information is available for Mediterranean environments, where green manure species and strategies may be other than those of northern-temperate and tropical regions. Relationships were found for maize shooting (Neff = -3.61DW + 29.75N%; R2 = 0.67), flowering (Neff = -1.32DW + 27.47N%; R2 = 0.66) and physiological maturity (Neff = -4.84DW + 50.43N%; R2 = 0.74) (DW = incorporated biomass, N% = N concentration).
