ABSTRACT
A field experiment was conducted at Crop Research Centre, near polyhouse, ITM University, Gwalior (M. P.) during rabi season of 2021-22. The experiment was laid out in factorial randomized block design with nine treatment combinations, which included three nitrogen levels (viz., N1–30 kg N/ha, N2–60 kg N/ha and N3–90 kg N/ha), three phosphorus levels (viz., P1–20 kg P2O5/ha, P2–40 kg P2O5/ha and P3–60 kg P2O5/ha) and one control (N0–0 kg N/ha + P0–0 kg P2O5/ha). Each treatment was replicated thrice. The results of the experiment revealed that increase in the application of nitrogen and phosphorus significantly increased the yield of safflower viz., number of capitula per plant, number of seeds per capitula, test weight (100-seed weight), straw yield (kg/ha), biological yield (kg/ha) and harvest index (%) in safflower. The application of 90 kg N/ha and 60 kg P2O5/ha were significantly superior over the application of 30 kg N/ha and 20 kg P2O5/ha.
Key words: Safflower, nitrogen, phosphorus, yield parameters, harvest index
