The experiment on response of stages of harvesting and post harvest ripening duration to seed quality in bottle gourd [Lagenaria siceraria (Mol.) Standl.] was carried out during summer, 2019. The treatments consist of three stages of fruit harvesting 40,50,60 days after anthesis (DAA), four stages of post harvest ripening (no post harvest ripening, 10 days PHR, 20 days PHR, 30 days PHR) and their combinations. Significantly maximum germination (84.13%), seedling length (23.57 cm), seedling dry weight (206.76 mg), moisture content (8.82%), vigour index-І (1898.10) and vigour index –ІІ (17628.26) and low electrical conductivity (0.498 dSm-1g-1) were recorded in H2 (fruit harvested 50 days after anthesis) whereas the highest germination (74.95%), seedling length (22.16cm), seedling dry weight (206.09 mg),vigour index-І (1702.25) and vigour index–ІІ (16070.48) and low electrical conductivity (0.552 dSm-1g-1) were obtained in P2 ( 20 days post harvest ripening ). Response of stages of harvesting at 50 days after anthesis and post-harvest ripening of 20 days (H2P2) gave good seed quality with significantly maximum germination (95.33%), seedling length (27.23cm), seedling dry weight (258.29mg) and least electrical conductivity of seed leachates (0.424dSm-1g-1) Hence, it may be concluded that bottle gourd should be harvested at 50 days after anthesis and 20 days post harvest ripening for production of better seed quality.
