Abstract:
A study was carried out in order to evaluate a cropping system comprising legume rotation and green manure with maize and kenaf and their nitrogen (N)response, in such systems. The legume used was L.Culinaries and the trials were conducted in Trikala (central Greece), on Endisol infertile sandy soil. The obtained results showed a positive response in L.Culinaries incorporation on maize seed yield in all treatments especially, in relation with N uptake. The same response showed the results for final yield of kenaf. Maize seed yield obtained with L.Culinaries incorporation, treatment fluctuated between 9t/ha and 11.7t/ha, while in the control plots (depended only in Nsupply), maize seed yield fluctuated between 7.5 t/ha and 10.6 t/ha. Although the recovery fraction was rather low (30%), a notably impact of green manure and rotation treatment was found. Contrary, the recovery fraction for kenaf was 70%, demonstrated a significant effect of incorporation treatment. The maximum dry kenaf biomass was recorded in incorporated plots (21.4 t/ha) and the minimum in control plots (16.5 t/ha).The NUE was about 48 KgKg 1 for maize and 76 KgKg1 for kenaf.
