Abstract: Safflower is an important rabi oilseed crop. Safflower has a superior adaptability to scanty moisture conditions. It has been under cultivation in India either for its colored florets and much valued oil. Productivity of safflower needs to be increased as this is a cash crop of small and medium holding farmers. There is urgent need to develop suitable management practices and genotypes to make safflower cultivation a successful proposition under Marathwada region of vertisols. In view of the above, it was felt necessary to study the effect of sowing time and suitable genotype under irrigated conditions. The present investigation has been implemented during rabi season of 2018-19 at experimental farm, Department of Agricultural Botany, College Of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was laid out in split plot design comprising sixteen treatments with four main plots i.e. irrigation applied at stem elongation stage (I1), irrigation applied at branching stage (I2), irrigation applied at flowering stage and Irrigation applied at all three selected stages (control) with 4 sub plots of varieties, i.e., PBNS 12 (V1), PBNS 86 (V2) and Sharda (V3) and PBNS 40 (V4). All the treatments were replicated three times. Well irrigated plants, i.e., irrigation treatment at three selected growth stages (I4) recorded significantly highest plant height, number of functional leaves, leaf area, leaf dry weight per plant, relative water content and chlorophyll content than other irrigation treatment. The yield attributes viz., number of capitula per plant and number of seeds per capitulum were observed significantly highest in irrigation treatment I4 followed by I2. Irrigation treatment at all three selected stages (I4) and irrigation at branching stage (I2) recorded high seed yield, biological yield and oil content. Genotypes, PBNS 12 and PBNS 86 recorded significantly highest plant height, number of functional leaves, leaf area and yield attributes viz., number of capitula per plant, number of seeds per capitulum and seed yield and biological yield than other varieties.
