Le résumé fourni par la source

The present experiment was conducted at the Fruit Nursery, College of Horticulture, Banda University of Agriculture and Technology, Banda during 2022-23. The results showed that T2 treatment., seeds dipped GA3 500 ppm for 24 hours, took the minimum germination time of 9.24 days, maximum germination percentage of 59.38% and survival rate of 60.25%. The highest earliness index (0.603), vigour index-I (809.10), and vigour index- II (244.99). The maximum plant height (12.78 cm), stem diameter (0.37 cm), leaf number (10.46), leaf area (24.24 cm²), fresh seedling weight (6.09 g), and dry root weight (2.89 g) at 120 days after sowing. The maximum root length (21.16 cm), number of secondary roots (2.37), fresh root weight (3.65 g), and dry root weight (1.60 g) at 120 days after sowing. Second factor results performed in mixed media T4 (soil, FYM, cocopeat 1:1:1), the minimum number of days taken for seed germination 10.66, maximum germination percentage of 54.38% and survival rate of 57.41%. The highest plant height (12.33cm), diameter of stem (0.39), number of leaves (9.74), leaf area 24.1 cm2), fresh shoot weight (5.54g), dry weight of shoot (2.61g), length of primary roots (19.16 cm) at observed 120 DAS and highest number of secondary roots (2.51), fresh weight of roots (3.78g) and dry weight of roots (1.59 g) at 120 days after sowing. Both types treatments showed effective in improving seedling establishment and growth, indicating their potential use for optimizing chironji propagation in nursery conditions.
