Kinetin is a synthetic cytokinin that promotes lateral branch development in leafy vegetables by releasing apical dominance and initiating axillary bud activation. Identifying the optimal concentration of kinetin, correct growth phase for its application and the most effective delivery method is essential to maximize crop performance and productivity. To explore its potential in fenugreek (Trigonella foenum-graecum L.), a factorial field experiment was conducted with the primary objective of determining the most effective kinetin dose (25, 50 and 75 ppm) and application timing (45, 60 and 75 DAS) for enhanced crop productivity and seed physiological quality under mid-hill field conditions. Among all treatment combinations, foliar application of 75 ppm kinetin at 45 DAS (D3S1) significantly enhanced vegetative growth, reproductive attributes and seed quality parameters. This treatment also achieved the highest leaf and seed yields, harvest index and biological efficiency. Additionally, superior seed vigour indices and reduced electrical conductivity indicated improved seed membrane integrity. The D3S1 treatment combination thus proved to be agronomically effective and economically viable, though it warrants validation across multiple agro-climatic regions for broader applicability

The study concluded that the treatment D3S1 (6-BA @ 75 ppm at 45 DAS) was the most effective among all treatments and control. It gave the highest leaf and seed yields along with superior yield-attributing traits like pod length, pods per plant, and seeds per pod. Seed quality parameters such as test weight, germination, seedling vigor, and lowest electrical conductivity were also best in this treatment. It recorded the highest B:C ratio of 3.74:1 for leaf and 0.74:1 for seed production. Hence, this treatment is recommended for fenugreek cultivation in mid-hill regions of Himachal Pradesh after multi-location testing
