To develop a system for screening lentil and pea cultivars on the basis of their contribution to yield and quality of subsequent spring wheat and durum cultivars.


In general, the inclusion of pulse crops had no significant effects on agronomic parametres in either spring wheat or durum wheat, relative to a fallow-wheat scenario. Since no or very little nitrogen (N) fertilizer was added in our study, this suggests that the inclusion of pulses in wheat cropping systems carries economic and environmental benefits, by supplying most of the subsequent wheat crop’s N requirements. Results suggest that the choice of pulse cultivar is not of consequence in pulse-wheat cropping systems.
