Rehabilitation of food legumes through the management of phosphorus and improved small faba beans Moroccan varieties

Abstract

Three Moroccan faba bean varieties (V) (Viciafaba minor) Alfia 5, Alfia 17 and Alfia 21 were grown under four phosphorus (P) rates (0, 20, 80 and 160 kg P2O5/ha) in the INRA experiment station of Douyet in Meknes action site. The experimental design was a split plot with four replicates where P was affected to the main plot and variety to the sub plot. Two measurements were taken: the first one at flowering stage to estimate nodulation and biomass production the second one at harvest time to estimate grain yield and evaluate the residual effect of phosphorus treatments.
