A study was carried out to evaluate the effect of solid matrix priming of seeds on emergence (%), growth and fruit yield characters of bitter gourd (Momordica charantia L.) cultivar ‘Solan Hara’. The Experiment comprised of two vigour groups of seeds viz., ‘V1’ (High vigour seeds) and ‘V2’ (72 hours accelerated aged seeds/low vigour seeds) and five seed priming treatments viz., ‘P1’ (Solid matrix priming with Cocopeat), ‘P2’ (Solid matrix priming with Perlite), ‘P3’ (Solid matrix priming with Vermiculite), ‘P4’ (Seed soaking in water), ‘P5’ (Control -Without treatment).Investigation proved that low vigour seeds were inferior in respect of high vigour seeds in terms of seed physiological quality, emergence, growth and yield characteristics. Seed priming with Perlite for 72 hours proved its potential over other priming treatments, seed soaking and control (non-primed seeds) in both high vigour and low vigour seeds for agronomic attributes under study. High vigour seeds primed with Perlite ‘V1P2’ was found to be the best treatment for most of the traits understudy recording highest total field emergence (76.60%), fruit yield per plot (16.12 Kg) and per hectare (250.35 q). Similarly, Low vigour seeds primed with Perlite also recorded enhanced and improved total field emergence (73.83%) fruit yield per plot (9.28 Kg) and per hectare (143.26 q) compared to other low vigour treated and non treated seeds. From the present investigation it was inferred that that the extent of improvement w.r.t. attributes studied was more in low vigour seeds (V2) and seed priming with solid matrix carrier ‘Perlite’ can be used as a beneficial pre-sowing treatment to enhance the seedling emergence, growth and yield characteristics in bitter gourd.
