Face to face interview was performed with 135 respondents to collect the data with the help of questionnaire. Pearson’s correlation was also used to find out the relationship between the farmers characteristics and plant species diversity. The result demonstrated that a total of 88 plant species, 30 vegetables species, 29 different agroforestry practices and 6 different vertical layers were recorded in the homestead of the study area. Out of different categories of plant species, 40 timber, 25 fruits and 23 medicinal and other plants were recorded. Among the plant species Mango (Mangifera indica), Jackfruit (Artocarpus heterophyllus), Coconut (Cocos nucifera), Papaya (Carica papaya), Neem (Azadirachta indica), Mehogony (Swietenia macrophiylla) and Acasia hybrid (Acacia hybrida) were dominant species. Regarding to different agroforestry practices, a total of 29 different combinations were observed in the study area. Total six vertical layer was identified as (S = > 1.0 m, S = 1.1-3.0 m, S = 3.1-5.0 m, S = 5.1-7.0 m, S = 7.1-9 m and S 1 2 3 4 5 6 = > 9.0 m). Eight different characteristics of the farmers namely; educations, farm size, homestead size, annual income, expenditure, savings, knowledge on homestead agroforestry, socio-economic conditions of the respondents showed significant positive relationships with the numbers of diversified plant species, while negative relationship of diversified plant species was observed with age and family size. Higher fruit (0.79-0.99), timber (0.77-0.93) and medicinal (0.77-0.96) plant species diversity was observed in most of the unions of the studied area. Mango Jackfruit, Papaya, Coconut were dominant fruit species. Acasia hybrid, Mehogony were dominant timber species. Neem (Azadirachta indica), Tulsi (Ocimum americanum), Pudina (Mentha spicata), Areca nut (Areca catechu), Bohera (Terminalia bellerica), Bamboo (Bambusa sp) were dominant medicinal and other plant species. Results conclude that homestead agroforestry is a unique area for maintaining both plant diversity and productivity for farmers’ livelihood.

There were two Citrus tree species as like Pummelo (P), Sweet orange (SO) and three blackgram varieties as like BARI Mash-1 (V1), BARI Mash-2 (V2), BARI Mash-3 (V3) were used for the study. The analysis was done following Randomized Complete Block Design (RCBD) with three replications. In case blackgram the treatments were SV1 =Sole BARI Mash -1, SV2 =Sole BARI Mash -2, SV3 =Sole BARI Mash -3, PV1 =BARI Mash -1 with pummelo, PV2 =BARI Mash -2 with pummelo, PV3=BARI Mash -3 with pummelo, SOV1 =BARI Mash -1 with sweet orange, SOV2 = BARI Mash -2 with sweet orange, SOV3 =BARI Mash -3 with sweet orange. In case of citrus the treatments were SP = Sole Pummelo, SSO = Sole sweet orange, PV1= BARI Mash -1 with pummelo, PV2= BARI Mash -2 with pummelo PV3 = BARI Mash -3 with pummelo, SOV1= BARI Mash -1 with sweet orange, SOV2= BARI Mash -2 with sweet orange, SOV3= BARI Mash -3 with sweet orange. Results showed that citrus species had pronounced effect on blackgram crop growth at different days after sowing. Sole crop showed the highest value for most of the parameters at 30 and 70 DAS while at 45 DAS pummelo associated crops showed better performance. Sole pummelo associated crops also gave the highest yield. Blackgram varieties also had pronounced effect on growth and yield performance of citrus when grown in association. Growth characters were prominent with BARI Mash-2 at different DAS while yield contributing characters were found to be the best in BARI Mash-3.At 30 DAS sole BARI Mash-1 performed better but BARI Mash-2 in association with pummelo and sweet orange showed better performance. Unlike at 45 DAS the sole BARI Mash-1and BARI Mash-2 and pummelo associated BARI Mash-1, BARI Mash- 2 and BARI Mash-3 found to be better with growth parameters. At 70 DAS the BARI Mash-1 and BARI Mash-3 without association of citrus trees, and with association of pummelo was found to be better with growth parameters. BARI Mash-2 and BARI Mash-3 without association of citrus trees was found, but BARI Mash-1 and BARI Mash-3 with association of pummelo and BARI Mash-3 with association of sweet orange was prominent in case of yield and yield contributing characters. Result revealed that BARI Mash-1 and BARI Mash-2 with the association of pummelo and BARI Mash-3 with the association of sweet orange may be the better option for growing blackgram in agroforestry system.

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.
