Abstract
A field experiment was conducted at the research station of Higher Agriculture School of Kef located in a semi-arid region of Tunisia to study the effect of supplemental irrigation on yield and yield components of four Tunisian faba bean genotypes (Bachaar, Badii, Chahbi and locale). Two supplemental irrigations were applied at the flowering and pod formation stages. Results showed a significant effect of supplemental irrigation on biological yield (BY/P), seed number per plant (SN/P), 100-seed weight (100 SW), grain yield (GY/m2), harvest index (HI) and number of days to maturity (NDM). Grain yields under supplemental irrigation varied from 83.9 to 208.7 g/m2, and they varied from 18.6 to 65.8 g/m2 under drought conditions. Average 100-seeds weight increment due to supplemental irrigation condition was 52.8%. Results showed also that under rain fed condition, Bachar genotypes required minimum number of days to maturity (134.3 days). Drought susceptibility index (DSI) values for grain yield ranged from 0.8 to 1.13. Chahbi was relatively drought resistant (DSI values <1). This genotype proved high yielding and drought tolerant and can be incorporated in stress breeding programme for the development of drought tolerant faba bean varieties.
