This study investigated the effect of cold plasma treatment on seed parameters of Okra [Abelmoschus esculentus (L.)] cultivar P-8. The experiment comprising of seeds of two different age viz., ‘A1’ (One year old seed) and ‘A2’ (Two year old seed) and seven plasma treatment using glow discharge technique at FCIPT, Institute for Plasma Research, Gandhinagar, Gujarat, India. The seeds were pre-treated with power of 100 W for treatment durations viz., ‘P1’ (only vacuum, no plasma treatment), ‘P2’ (3 minute), ‘P3’ (6 minute), ‘P4’ (9 minute), ‘P5’ (12 minute), ‘P6’ (15 minute) and ‘P7’ (Control–Without treatment) during 2014. The seeds with different combination of treatments were evaluated for different seed crop characters. It has been observed that the plasma treatment of 12 minutes duration on A1 seeds could significantly improve days to first ripe fruit harvesting (103.25), plant height at final harvest (161.19 cm), number of ripe fruits per plant (15) and ripe fruit yield per plant (86.46 g) as compared to control. The number of seeds per fruit (56.43), thousand seed weight (55.91 g), seed yield per plant (47.55g), seed yield per plot (1.50 kg), seed yield per hectare (27.34 q) and percent seed recovery (52.49) was significantly increased in one year old seed as compared to control. Therefore, our results show that cold plasma treatment has important application prospects for increasing seed yield of okra.
