Abstract:

The Rabi season experiments conducted at SAU Tando Jam Agronomy Students Farm in 2020 and 2021 used a factorial randomized block design to investigate the impact of varying nitrogen (N), potassium (K), and zinc (Z) levels. Sixteen treatment combinations, with T2=N=30%, T3=N=15%, T4=K=10%, T5=N=45%+K=25%+Z=15%, T6=N=60%+K=35%+Z=20, and T7=N=90%+K=45%+Z=25%, were tested in triplicate. Optimal results were observed with the application of T7= N = 90% + K = 45% + 25%. Yielding the highest values for key parameters. Notably, plant height reached 83.85 cm and 79.91 cm, branches per plant were 27.70 and 21.88, capitula per plant totaled 18.62 and 17.71, and seed capitula per plant were 21.20 and 20.71. Additionally, test weight, seed yield, and stover yield peaked at 51.23 g, 17.89 qha-1, and 52.21 q ha-1, respectively. Conversely, the control group exhibited consistently lower values across all measured aspects, affirming the positive impact of the optimized N, K, and Z levels on safflower growth and yield. The results of this study contribute valuable information to agronomic practices, emphasizing the significance of carefully calibrated nutrient levels to maximize crop performance in the Rabi season.
