A field investigation was conducted at Oilseed research unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during rabi season 2022-23 with an object to find out suitable sowing date for safflower crop and to find out suitable varieties of safflower. The experimental site was fairly uniform in topography with clayey in texture and slightly alkaline in reaction. It was low in available nitrogen, medium in available phosphorus and rich in potash with moderate organic carbon. The experiment was laid out with twelve treatment combinations in split plot Design with three replications. Main plot consists of four sowing dates (S) viz. sowing in 39th MW (S1), 41th MW (S2), 43th MW (S3), 45th MW (S4) and sub plot consist of three varieties namely AKS-207 (V1), PKV-Pink (V2) and AKS-351 (V3).
The differences were significant among all the sowing dates in respect of the seed, straw and biological yield. The highest growth attributes, seed yield (2160 kg ha-1), straw yield (5590 kg ha-1) and biological yield (7750 kg ha-1) were recorded in 41st MW (S2). The next suitable sowing date was observed to be sowing in 43th MW (S3) in respect of seed, straw and biological yield. Quality parameter characters viz. protein content, protein yield and oil content, oil yield was significantly higher with sowing in 41st MW (S2) followed by sowing in 43rd MW (S3), 45th MW (S4) and 39th MW (S1). Sowing of safflower during the 41st MW (S2) recorded higher oil and protein yield, GMR (Rs. 125553), NMR (Rs. 90876) and B: C ratio (3.62) compared to sowing in 43rd MW (S3), 45th MW (S4) and 39th MW (S1). Variety AKS-351 (V3) showed significant improvement in growth attributes, yield attributes and recorded highest seed oil and protein yield, GMR (Rs. 112391), NMR (Rs. 77978) and B:C ratio (3.26) as compared to PKV-Pink and AKS-207.
