Propagation of Jackfruit by Modified Cleft Grafting as Influenced by Time of Operation

Abstract

The experiment was conducted to study the effect of time (season) of grafting on the performance of modified cleft grafting of Jackfruit at the BAU Germplasm Centre (GPC) of Fruit Tree Improvement Project (FTIP) of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh. The experiment consisting ten levels of grafting times, viz., 30^th March, 15^th April, 30^th April, 15^th May, 30^th May, 15^th June, 30^th June, 15^th July, 30^th July, 15^th August, was laid out in RCBD with three replications. The results revealed that grafting done on 14^th August showed the highest success (39%) and took the lowest time to first flush and first leaf opening (4.66 and 5.00 days, respectively) whereas the success rates were very low at the months of March, April and May. Likewise the highest vegetative growth of the grafted plants in terms of height, diameter, number of leaves, length and breadth of the leaves was found with grafting done on 14^th August.
