Abstract

Graded levels of potassium significantly influenced the growth, yield, quality, and economic returns of fenugreek, highlighting its critical role in optimizing crop productivity and profitability. The present investigation evaluated the impact of graded potassium levels on fenugreek growth, yield, quality, soil properties and economic returns during the Rabi season of 2023-24 at ICAR-KVK, Bangalore Rural (Karnataka). The field experiment was laid out in Randomized Block design with four replications having ten different combinations of potassium levels i.e. T1- [Absolute control]. T2- [PoP as per UAS (B)], T3- [T2 + potassium @ 10 kg ha-1], T4- [T2 + potassium @ 15 kg ha-1], T5- [T2 + potassium @ 20 kg ha-1], T6 – [T2 + potassium @ 25 kg ha-1] ,T7- [T2 + potassium @ 30 kg ha-1],T8- [T2 + potassium @ 35 kg ha-1],T9- [T2 + potassium @ 40 kg ha-1] and T10- [T2 + potassium @ 45 kg ha-1]. The results revealed that combination of recommended dose of fertilizers with 45 kg ha-1 potassium application (T10) significantly enhanced seed yield (1,745.75 kg ha-1), haulm yield (2,649.14 kg ha-1) and green leaf yield (6.72 t ha-1). Highest amount of crude protein (18.40%) and fibre content (7.85%) was observed with higher levels of potassium. Economic analysis revealed that T8 (35 kg ha-1 K) had the highest benefit-cost ratio (2.85) making it the most profitable treatment. The study underscores the vital role of potassium in optimizing fenugreek productivity and profitability.
