Abstract:

Crop yield and water use efficiency are determined by its genotype, environment, GxE and agronomic management. The performance of faba bean (cv. Samira) under different sowing time, sowing rate and soil moisture conditions was evaluated. Sowing time and soil moisture regimes were found to have significant effects on grain yield, water use efficiency and grain quality. Yield penalty associated with delayed sowing was not significant when the crop was irrigated in spring; irrigation water use efficiency was higher for late sown than for early sown faba bean. Late sown faba bean left higher amount of residual moisture in the soil than the early sown faba bean. Faba bean yield and water use efficiency could be improved by timely sowing and/or supplemental irrigation.
