An experiment was conducted at Setif in the 1987/88 season to study the response of four cultivars to three sowing dates and to supplementary irrigation. Early sowing in November significantly decreased the number of plants/m2, but significantly increased number of heads/m2. Supplementary irrigation increased number of heads/m2 by 42 over rainfed cultivation. Mean grain yields for the irrigated and non-irrigated treatments were 5160 and 680 kg/ha, respectively. Mean grain yield for November sowing was significantly higher than those obtained with later sowings. However, a significant sowing date x irrigation interaction was present. November sowing produced higher yield under irrigation, but lower yield under rainfed conditions as compared to later sowings. Significant variety x irrigation interaction was also detected. Under irrigation, cultivars Waha, ACSAD 65, and Vitron significantly outyielded Mondur, though without irrigation, Mondur developed the best yields at the two earlier sowings
