DIVERSITY OF MULTIPURPOSE TREE SPECIES IN THE HOMESTEADS AND IT’S IMPACT ON THE LIVELIHOOD OF THE FARMERS OF GOPALPUR UPAZILA IN TANGAIL DISTRICT
(DEPT. OF AGROFORESTRY & ENVIRONMENTAL SCIENCE, 2015) HAQUE, MD. AHSANUL
Plant di versity i n home gardens has a wi de socio-economic and agro-ecological roles includi ng production of food and a wi de range of other products. The recent study was conducted i n t wel ve villages of four unions under Gopalpur upazil a in Tangail district to explore the Multipurpose Tree Species (MPTs) di versity and it’s contribution on t he livelihood of the farmers. Out of 3334 farmers, a sample of 12% farm families was selected based on stratified random sampli ng procedure. Thus, 400 farmers and finally 80 farmers were selected by using Yamane formula. Fi ve percent (0.05) level of probability was used as the basis for rejection of any null hypothesis throughout t he study. Data were collected through personal interview by the researcher himself during 15 September to 25 December, 2014 usi ng the interview schedule. Farmer ’s opi nion regar ding multipurpose tree species in the homesteads and its i mpact on socio-economic development was t he dependent variables of the study. Ten characteristics were age, education, occupation, family member, farm size, homestead area, annual income, socio-economic aspects, knowledge on MPTs i n homestead agroforestry and problem confrontation constituted the independent variables of this study. Species di versity of MPTs i n the homesteads agroforestry was measured by Shannon-wiener index (H). In case of all species, the highest index (H) val ue found in Jhaoail union (H=3.017) and the lowest index (H) val ue found in Dhopakandi union (H=2.967). Akashmoni (12.53 %), Jackfruit (18.28 %), Neem (1.45%), Bamboo (3.72%), Mander (2.03%) were found as dominant trees for timber, fruit, medicinal, fodder and fuel wood species, respectively i n Gopal pur upazila. MPTs had direct impact on i ncome of the farmers. Small farmers had average i ncome 13.21 thousand t aka, Medi um farmers had average i ncome 29.33 thousand t aka and large farmers had average i ncome 45.79 thousand taka from MPTs i n homesteads agroforestry in Gopalpur upazila.
POPULATION ECOLOGY, DAMAGE EXTENT OF MAJOR INSECT PESTS AND MANAGEMENT APPROACHES FOR JHUM AND RICE-COTTON INTERCROPPING IN CHOTTOGRAM HILL TRACTS OF BANGLADESH
(Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, 2019) HAQUE, MD. AHSANUL
The study comprised four experiments conducted at four separate trials at jhum and intercrop fields in different hills of Bandarban, Rangamati and Kagrachari during March 2014 to February 2016 to find out insect pests of existing cropping system, identify common insect pests their population dynamics and extent of damage in addition evaluate effective pest management approaches for jhum and rice-cotton intercropping system at hill region of Bangladesh. The field experiments were conducted in RCBD from farmer’s field of jhum and rice-cotton intercropping on hill during April 2015 to January 2016. Among the 150 farmers, average, 19.33% received pest management and other training whereas 80.67% did not received any types of training. Jhumian people were used to their traditional practice to suppressed pest and diseases. Forty eight insect mite pests on rice, country bean (22), hill sesame (30), cowpea (17), yard long bean (16), marpha served as (18), okra (13), eggplant (24), chili (11), maize (12), roselle (6), whereas cotton plant serve as a host for an extensive range of insect mite (45) similar to rice. Among them leaf webber on sesame, BSFB on eggplant, fruit flies on marpha and cucumber, mite and thrips on chili and red cotton bug on cotton were reflected as major insect mite pests. Nonetheless phloem-feeders bugs, aphid, jassid, whitefly, leaf feeding epilachna beetle and grasshoppers were abundance extent of damage were maximum on different jhum crops and intercrops thus considered as major. The infestation by the major and promising insect and mite pests and their abundance, seasonal incidence their extent of damage of jhum and hill rice-cotton intercrop significantly varied with mean temperature, rainfall and humidity. Farmer’s practices of Jhumian people treatment were less effective to suppress the insect pests predominant on hill districts. The rate of infestation, decreasing invasion over untreated control, yields, monsoon season, accessibility at hills, their traditional practices on different crops in jhum and hill rice-cotton intercrop, chemical treatment T (spraying Voliam Flexi 300 SC @ 0.5 ml Liter -1 3 water at 25 days interval) was most effective and other chemical treatments also performed significant and recovering of yield than traditional practices and untreated control plots.
