Biopriming is a very important seed invigoration technique for rapid germination. In order to utilize the biopriming influence on seedling growth in snake gourd (Trichosanthes cucumerina), this experiment was conducted to study the seed biopriming with liquid biofertilizers on snakegourd cv. CO2 for better germination and seedling growth. The results showed that the effect of biopriming was significant on germination percentage, seedling dry weight and seedling vigour in snakegourd. Seeds bioprimed with Azospirillum20% concentration for 18h was the best and suitable biopriming treatment. This treatment showed a higher speed of germination (5.6), percentage of germination (84%), dry matter production (1.187g 10 seedlings1) and vigour index (3969) compared to other concentrations, durations and over the other treatments.
