| dc.description.abstract | The study was carried out to investigate the status of citrus biodiversity and their relative
prevalence in the homestead area of Jaintapur Upazila in Sylhet District, during 3 July to 25
November 2013. Sixty local people from six Unions were interviewed to investigate the
status of citrus biodiversity and their relative prevalence in the study area. It also explored the
relationships between the selected characteristics (independent variables) namely age,
education, family size, homestead land size, farm size, number of trees in homestead,
problem confrontation during citrus cultivation, total annual income, annual income from
citrus, training participation, organizational participation, socio-economic aspect and number
of citrus species in homestead (dependent variable). Correlation analysis indicates that five
selected characteristics of the farmers namely homestead land size, number of trees in
homestead, total annual income, annual income from citrus and socio-economic aspect
showed significant positive relationships with the diversity of citrus species, while no such
significant relationship was observed with age, education, family size, farm size, problem
confrontation and organizational participation of the farmers. Training participation of the
farmers had negative relationship with the diversity of citrus species but not significant. A
total number of 15 citrus species were recorded from the studied homestead areas. Among
these tree species the most prevalent species was Zara lebu followed by Ada jamir, Komola
lebu, Kagzi lebu, Batabi lebu, Deshi lebu, Kurun jamir and Elachi lebu. The highest number
of citrus species was found in Charikata Union followed by Fatehpur, Chicknagul, Jaintapur,
Darbasta whereas the lowest number of citrus species was identified in Nijpat Union. Sorbati
lebu (Citrus limmetta) and Deshi lebu were identified as endangered while Kolombo lebu and
Pati lebu as critically endangered species of citrus. Kot lebu, Tuna lebu and Sulang lebu are
extinct from the study area. On the other hand Zara lebu (Citrus medica), Ada jamir (Citrus
assamensis), Kata jamir (Citrus jambhiri), Kurun jamir (Citrus aurantium), Elachi lebu
(Citrus limon), Kagzi lebu (Citrus aurantifollia), Komola lebu (Citrus sinensis) are found in
safe condition as they are grown commonly in most homestead of study area. | en_US |
