Abstract: Seed priming is an effective, eco-friendly method to promote seed germination and seedling vigor of okra to overcome the reduced and delayed germination in fresh or stored okra seeds caused by seed hardness. An experiment was carried to evaluate the effects of different priming on okra seeds germination and seedling vigor using Arka Anamika variety at Horticulture lab of Agriculture and Forestry University, Rampur, Chitwan, Nepal. Investigation was carried out with 6 treatments (T1: seed priming with tap water, T2: seed priming with 200ppm NAA solution, T3: seed priming with 10% PEG-200 solution, T4: seed priming with 200ppm GA3 solution, T5: seed priming with 5% Trichoderma solution and T6 no priming) with 4 replications in Complete Randomized Design (CRD). Seeds primed with T1 to T5 were soaked for 24 hours and shade dried for 6 hours before sowing. Priming with T4 was found to be best in terms of maximum seed germination (60.12%), seed vigor index (5772.68 cm), mean germination rate (7.53 seeds per day). The highest shoot length (81.40 mm) was observed at T1 whereas enhancement of root length occurred with the priming with T3. All treatments had a significant positive effect on all the germination parameters in comparison to control. The study concluded that GA3 priming enhanced germination as well as seed vigor in okra and hydro priming and tricho-priming can be used as an alternative to GA3 priming among farmers in Nepal.
