Abstract/ Executive Summary:

A study was conducted to identify the problem of off-season jackfruit cultivation in the southwestern region of Bangladesh during July 2003 to March 2004. Data were collected from randomly selected 140 respondents of Sadar Upazila of Jessore. Data were collected on insect and disease infestation in order to determine the problem confrontation. A total of 3774 jackfruit trees were found in the homestead of the respondents with an average of26.96 among which 206 off-season jackfruit trees with an average of 1.47 were identified. Most of the jackfruit growers have 1-2 off-season jackfruit trees in their garden. Most of the jackfruit trees bear flower during August to October and the fruiting age was found less than 20 years. The majority of them do not take control measures against disease and insect infestation. The respondents addressed water deficiency, a disease caused by rhizopus, insect infestation by fruit borer and nutrient deficiency as the causes of flower and fruit drop. The vital problems of off-season jackfruit cultivation were insect and disease infestation, lack of information and lack of good varieties.

Location: Sadar upazilas of Jessore district

Start Date: 00-07-2003

End Date: 00-03-2004

Program Area: Risk Management in Agriculture

Commodity: Jackfruit, Problem

Objectives:

Therefore, the study on variety development for the off-season jackfruit is essential which will boost up jackfruit plantation and higher production of fruit in the country during the lean period. This in turn will generate employment, more economic return, and nutrition of people as well. Considering these points the present study was undertaken to identify the problems of jackfruit cultivation in the south-western region of Bangladesh.

Methodology:

Data were collected from randomly selected 140 respondents of Sadar Upazilas of Jessore district on causes of flower and fruit dropping, insect and disease infestation and problem confrontation of jackfruit cultivation. To know the situation about insects and disease infestation information was collected by asking a question about the symptoms and the control measures they adopted. An item was prepared in the interview schedule in this purpose, where the names of diseases and insects with their symptoms and control measures were asked. All the names of the diseases and insects were compiled from the interview schedule. The problems obtained from the respondents were categorized into 4 types viz. severe, moderately severe, negligible and not at all. The data obtained from the interview were coded and tabulated in a data sheet. All personal traits were categorized and arranged in simple tables for descriptions. Then the frequency and percentage of the respondents in different categories were calculated.

Majority of the respondents (77.14%) of opined that water deficiency was a major cause for flower and fruit dropping. However, a little proportion (8.58%) of them expressed in favour of diseases and 7.14 percent of each of them opined for insect and nutrient deficiency symptoms, respectively. The treatments for the protection of flowers and fruit dropping are shown in table 2. Most of the respondents (95.71%) do not take any measures for controlling the dropping of fruits and flowers. Only a few of them (4.29%) used fungicide against the problem. But from the studies, it was observed that none of them use insecticide and do not practice intercultural operations to protect the dropping of fruits and flowers.

From the survey, it was found that the off-season jackfruit plants were damaged by rhizopus fruit rot (100%) and there was no claim for other diseases. All the respondents reported that their jackfruit trees were infested by fruit borer (Diaphania caesalis) and a few respondents (10.19%) claimed that their trees were damaged by bud weevil (Ochyromera artocarpi). Bud weevil generally damages those trees whose age used to become more than 20 years.

Achievement/Findings:

The problem confrontation of jackfruit cultivation is recorded. From the study, it was found that the main problems of jackfruit cultivation were insect and disease damage (100%), lack of information (97.14%), lack of good variety (95.71%), and poor productivity (87.14%). According to the extent of severity these problems were classified into severe, moderately severe, negligible and not at all. In case of disease infestation, only 4.29% of the respondents said that it was a negligible problem and 44.28% of them mentioned it as a moderately severe problem. In the case of insects, only 2.86% of the respondents said that it was a negligible problem and 41.42% of them reported as a moderately severe problem. And in case of lack of information about fruit cultivation, 55.71% of respondents identified it as a moderately severe problem and 20% as a severe problem.
