Effects of different planting time on their survival and growth parameter of different types of jackfruit at Prayagraj, Uttar Pradesh

Abstract

The present experiment was carried out at Horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj, U.P, India, during the (2023-2024). A one and half year old Seedling and grafted jackfruit plants which is (approx. 65 no. of plants) The experiment was laid out in Factorial Randomized Block Design {FRBD} with 20 treatments and each was replicated thrice with 10 varieties viz., Singapore, Varashree y, redmoon, G 11, Wild jack, Kini Singapore, prashanthi, janagere, Sampoorna, shankara of jackfruit. Among the varieties, maximum plant height (87.94), number of branches per plant (6.48), number of leaves per plant (62.93), leaf area (68.87 cm2), leaf width (7.30 cm), leaf length (12.98 cm), survival percentage (100.00), mortality percentage (0.00) and chlorophyll content (SPAD) (62.40) were recorded in Varashree y. Transplanting of jackfruit days after transplanting recorded significantly higher plant height (61.95 cm), number of branches per plant (4.73), number of leaves per plant (47.91), leaf area (cm) (50.22), leaf width (cm) (5.68), leaf length (cm) (10.34), survival percentage (66.67), mortality percentage (33.32), chlorophyll content (SPAD) (51.04) over other dates of planting. Among the treatment combinations V2: Varashree y emerged as the best combination with regard to vegetative growth and survivival percentage of jackfruit.
