Abstract/ Executive Summary:

An experiment was conducted at the Jackfruit Research Project, Horticulture farm of Bangladesh Agricultural University, Mymensingh during the period from December 2002 to July 2003 with the objectives to determine the physical characteristics of three types of Jackfruit at different harvesting time vis a vis appropriate time of harvest of them. Physical characteristics of three types indicated that bulb weight (%) decreased and rind weight (%) increased at later stages of harvesting. The bulb of Ghila was very soft at early harvesting stage of harvesting. The edible portion was found to be the highest (59%.95%) in mid harvesting time and Dorosha type gave the maximum (55.21%). The fruit of late harvesting time had vivparous seed. Early and mid harvesting times were found to be better in all three types of Jackfruit and Ghila was found to be superior.

Keywords: Physical characteristics, Harvesting time, Jackfruit

Location: Jackfruit Research Project at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh.

Start Date: 00-00-2002

End Date: 00-07-2003

Program Area: Crop-Soil-Water Management

Commodity: Jackfruit

Objectives:

To find out the appropriate time of harvesting for three types and physical characteristics of Jack fruit at different harvesting.

Methodology:

The experiment was carried out from 2002 to July 2003. Three types of jackfruit were selected from Jackfruit Research Project at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh. The selected plants were three types namely Khaja, Ghila and Dorosha and harvested at different times namely early harvesting, mid harvesting and late harvesting. The selected plants have been grown on medium high land of old Brahmaputra flood plain soil tract of Bangladesh. The soil was sandy loamy having pH 6.6. The study was conducted in a randomized complete block design with three replications. Time and types served as different factors. Thus there were three times of harvesting and three types of Jackfruit. Mature jackfruits were collected from the plant and kept at ambient temperature for further study. Analysis was done in the laboratory of the Department of Food Technology and Rural Industry, Bangladesh Agricultural University, Mymensingh. By using different parameters physical characteristics were studied. The collected data were analyzed statistically and adjusted with least significant difference test (LSD) at 5% and 1% level of probability.

Achievement/Findings:

Based on the results it might be concluded that mid and early harvesting times were better for the jackfruit but late harvesting time was not desirable as the quality of fruits deteriorates with time.
