Abstract
The present investigation entitled, “Effect of Zinc Nanoparticles Seed Treatment on
Quality Seed Production in Bitter Gourd” was carried in the laboratory and research farm of
Department of Seed Science and Technology, Dr Yashwant Singh Parmar University of Horticulture
and Forestry, Nauni, Solan (HP) during 2022-2023. The experiment was laid out in open field
conditions with Randomized Block Design having fourteen treatments replicated three times while
laboratory experiment was conducted in Completely Randomized Design replicated 4 times. Out of
the 14 treatments, 9 treatments comprised of seed priming with zinc nanoparticles @ 50 ppm, 100
ppm and 150 ppm for 12, 24 and 48 hours, 3 treatments comprised of seed coating with zinc
nanoparticles @ 50 ppm, 100 ppm and 150 ppm, 1 treatment comprised of seed soaking in water for
36 hrs in addition to control. Seed priming with ZnO NPs @ 150 ppm for 24 hrs (T8) was found
superior over all other treatments in terms of germination (98.25 %), seedling length (25.23 cm),
seedling dry weight (144.25 g), seedling vigour index-I (2478.86), seedling vigour index-II
(14171.85), days to 50% emergence (10.33 days), total emergence (79.56 %), plant height 30 DAS
(80.06 cm), days to first picking (80.33 days), harvest duration (28 days), fruit length (17.11 cm), fruit
weight (116.33 g), number of fruits per plant (13.66), number of seeds per fruit (24.18), number of
seeds per plant (330.30), seed yield per plot (293.97 g), seed yield per hectare ( 483.91 kg/ha), 100
seed weight (17.20 g) and maximum B:C ratio (1.84: 1) which was closely followed by seed priming
with ZnO NPs @ 150 ppm for 48 hrs (T9). Therefore, seed priming with ZnO NPs @ 150 ppm for 24
hrs (T8) can be recommended for commercial seed production of bitter gourd after multi-location
testing.
