Abstract:  A field experiment was conducted under arid agroclimatic conditions of Adaptive Research Farm, Karor Lal Esan, Layyah, Pakistan, to assess the performance of three sunflower cultivars (Hysun-33, FH-331, and ORISUN-648). Experiment was arranged in a randomized complete block design (RCBD) and statistical analysis was performed using the software Statistic 8.1 software. The results showed significant differences among the cultivars in terms of growth and yield contributing parameters.. Hysun-33 produced maximum yield (1136 kg acre-1), surpassing other cultivars in plant height (177.7 cm), head diameter (19.27 cm), and 1000-seed weight (57.0 g). FH-331 followed closely, producing a yield of 992.0 kg acre-1 with an average plant height of 163.3 cm, 1000-grain weight of 5.0 g, and head diameter of 18.7 cm. Conversely, ORISUN-648 demonstrated the lowest performance across all measured parameters, yielding 880.0 kg acre-1 with a plant height of 155.7 cm and a head diameter of 17.0 cm. Hysun-33 took maximum days (124 days) to reach maturity, followed by FH-331 (120 days), while minimum days to maturity (117 days) were observed for ORISUN-648. The higher yield of Hysun-33 under arid conditions makes it a promising candidate for further evaluation as a high-yielding sunflower cultivar in Pakistan’s arid regions, particularly Layyah.
