The study was conducted in three union viz., Chandrakona, Pathkata and Baneswardi under Nakla upazila of S+herpur district to observe the tree diversity in the homestead area and to explore the relationships with the different characteristics of the farmers. A structured personal questionnaire was used for collecting data during the period from 15 July to 15 September, 2011. Ninety farmers were selected randomly for the study area for data collection.
Average age, homestead size, annual income of the farmers of Nakla upzila of Shepur district were 42.38 years, 0.057 ha and 84600 Tk., repectively. The knowledge about agroforestry of the farmers ranged from 15-45 marks with an average of 17.70 marks.
A total of 52 tree species, 14 vegetable species, 9 agroforestry practices and 5 different vertical layers were recorded in the homestead of the study area. The different categories of trees as 15 timber species 19 fruit species, 6 fodder species, 6 medicinal species, 4 ornamental & 2 other species were recorded. Among the trees species, Supari, Jackfruit, Akashmoni, Raintree Mango, Mahogoni, Coconut, Guava and Jamrul were dominant species. Average of 24.33 plant species were recorded in each homestead and species density was 4.27 per 100 m2 in the homestead area. Average tree population density was 61 per homestead and tree population density was 10.60 per 100 m2 in the homestead area. A total of nine different combinations were recorded as different Agroforestry practices. Among the nine agroforestry practices Mahogoni-Halud, Litchi-Banana-Halud and Mahogoni-Akashmoni-Halud was the dominant practices in the study area and others practices were found sporadically. Vertically different layer or strata was observed in this area. In this study total five layer was identified as L0 (> 1 m), L1 (2-3m), L2 (3-5m), L3 (5-7m), and L4
Five selected characteristics of the farmers namely, farm size, homestead size, cultivable land size, annual income and knowledge about trees showed significant positive relationships with the diversity of tree species, while no such relationship was observed with age, education, family size, knowledge about agroforestry.
