This study investigated the effect of cold plasma treatment on growth, fruit and seed parameters of bell pepper (Capsicum annuum L.) cultivar California Wonder. The seeds were exposed to various durations of oxygen cold 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 of 0, 3, 6, 9, 12, 15 minutes. The changes in surface morphology of plasma treated seeds were studied by Scanning Electron Microscopy (SEM) and Contact Angle Goniometer. The treatments comprised of primed and non-primed seeds and seven seed plasma treatments. Along with plasma treatment, seeds were also treated with standard osmopriming method for comparison. The plasma treatment alone as well as in combination with osmopriming up to 6 minutes plasma treatment was found superior over all treatments in terms of growth, fruit and seed yield characters. Osmoprimed seeds exposed with 6 minutes plasma were also found to be best treatment for most of the traits recording plant height 30 DAT (18.97 cm), days to first mature fruit picking (75.33), number of fruits per fruit (17), fruit yield per plant (1.00 kg), Number of seeds per fruit (190 g) and thousand seed weight (4.35 g).
