Abstract/ Executive Summary:

An experiment was conducted at the Fruit Research Farm, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during 2018-19 to study the effects of time and variety on the grafting success of jackfruit. There were two factors in the experiment viz., time of grafting (March, April, May, June, July, August, September, October, November, December, January and February) and variety of jackfruit (BARI Kanthal-1 and BARI Kanthal-2). Time of grafting and variety alone and in combination influenced the success of grafting and days required to sprouting. The highest grafting success (83.4%) was recorded in January grafting with BARI Kanthal-1 followed by that of February grafting with BARI Kanthal-1 (80.4%), January grafting with BARI Kanthal-2 (80.0%) and February grafting with BARI Kanthal-2 (76.8). The lowest success was obtained from September grafting with BARI Kanthal-2 (26.7%).

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Jackfruit

Objectives:

To study the effects of time and variety on the grafting success of jackfruit.

Methodology:

The experiment was conducted at the Fruit Research Farm, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during 2018-19. There were two factors in the experiment viz., Time (March, April, May, June, July, August, September, October, November, December, January and February) and variety (BARI Kanthal-1 and BARI Kanthal-2) of jackfruit. The rootstock seedlings were raised in 10 x 8 cm poly-bags. The poly-bags were filled with soil and cow- dung in equal ratio. Dormant shoots of the current year’s growth from 11 years old trees were used as scions. The length of scions was about 6-8 cm. Grafting was done in the first week of every month. The experiment was laid out in Randomized Complete Block Design with three replications. Thirty grafts in each variety and time constituted a experimental unit. Cleft grafting was employed for the experiment. The prepared grafts were kept under partial shade in the mist house. The grafting tape was removed when the grafts were confirmed. Data on grafting success and days to bud break were recorded. Data were analyzed statistically and the mean separation was done by DMRT.

Achievement/Findings:

Considering grafting success, January and February were the suitable time for cleft grafting of jackfruit. The experiment will be conducted next year for further confirmation.
