This three-year study demonstrated that foliar applications of growth regulators significantly enhanced the productivity and profitability of linseed under rainfed conditions of Palampur. While GA 400 ppm and Auxin 1.0 ppm + GA 200 ppm treatments produced the highest seed yields (1416 and 1426 kg/ha, respectively) through substantial improvements in plant height, branching, capsules per plant, seeds per capsule, and seed weight, the economic analysis revealed a different optimal treatment. Auxin 2.0 ppm emerged as the most economically viable option with the highest net returns per rupee invested (2.07) and superior net monetary returns (39573 Rs/ha), despite generating moderately lower yields than GA treatments. This discrepancy occurred because gibberellic acid applications, although yield-enhancing, incurred significantly higher input costs that reduced overall profitability. The findings emphasize that growth regulator recommendation for linseed cultivation should balance biological efficacy with economic efficiency, with Auxin 2.0 ppm representing the most prudent choice for farmers seeking to maximize returns under similar agro-ecological conditions

The study clearly demonstrates that foliar application of growth regulators significantly improves the productivity and profitability of linseed under rainfed conditions. While GA 400 ppm and Auxin 1.0 ppm + GA 200 ppm maximized seed yield, Auxin 2.0 ppm emerged as the most economically viable treatment, offering the highest net returns and benefit-cost ratio. Thus, Auxin 2.0 ppm represents the most practical and profitable option for linseed growers in similar agro-climatic regions
