Effect of seed priming on growth and yield attributing traits of okra (Abelmoschus esculentus L.)

Okra (Abelmoschus esculentus) is a significant vegetable crop grown for its tender pods. Despite the economic and nutritional importance, it faces challenges of poor seed germination and inconsistent seedling establishment. Seed priming aids in hastening and enhancing the consistency of plant growth and seed germination. It is an effective way of promoting seed germination and vigour of okra by alleviating seed dormancy. The study aims to address the gaps by systematically evaluating the effect of different seed priming treatments on germination trait, growth and yield of okra. A research trial was investigated at the vegetable field, Department of Horticulture, Lovely Professional University, Phagwara, Punjab during the period of 2024-2025 to assess the response of okra variety Pusa Sawani to seed priming. A total of 7 treatment combinations meticulously crafted comprising of salicylic acid, GA3 and cow urine under varying concentrations. The experiment was structured in a Randomized Block Design (RBD) with three replications. Findings revealed that okra seeds primed with GA3 at 200 ppm and those treated with GA3 at 200 ppm combined with salicylic acid at 100 ppm exhibited the highest seedling length, number of branches per plant, number of leaves per plant, stem diameter, fruit yield, days to 50 % flowering, fruit length, fruit weight, number of fruits per plant and fruit yield. It can be inferred that out of all the priming treatments, seeds primed with GA3 at 200 ppm performed the best, demonstrating quicker germination, enhanced growth, yield and quality.
