In this study the 25 years old previously established mahogany tree were used as tree components. As leafy vegetable Kalmi, Red Amaranth, Indian Spinach and Stem Amaranth were used. The experiment consists of two factors: Factor A: Orientation of planting (2) - 0: East facing, 02: West facing; Factor B: Distance of planting (5 levels)- Do: Planting leafy vegetables under Ml sunlight, Dj: Planting leafy vegetables 3.5 m apart from mahogany trees, 1)2: Planting leafy vegetables 4.0 m apart from mahogany trees, 1)3: Planting leafy vegetables 4.5 m apart from mahogany trees and 1)4: Planting leafy vegetables 5.0 m apart from mahogany trees. The experiment was conducted with Randomized Complete Block (RCI3D) with three replications The result revealed that, due to orientation of planting, in case of Kalmi, Red Amaranth, Indian Spinach and Stem Amaranth, the tallest plant,the highest yield and light intensity was recorded from 0, where light intensity and soil moisture were maximum. Soil temperature was minimum. On the other hand yield of four leafy vegetables were the lowest at west facing (02). Light intensity and soil moisture were minimum. Soil temperature was maximum. The yield of four leafy vegetables were the best from 4.5 m apart from Mahogany trees (03). On the other hand yield of Kalmi, Red Amaranth, Indian Spinach and Stem Amaranth were the lowest from 3.5 m apart from Mahogany trees (13 1). Light intensity was the highest at treatment combination of 02D0 and the lowest light intensity was observed at treatment combination oIO 2D2. The yield per hectare (41.22, 44.82. 55.53 and 44.25 ton, respectively) of four leafy vegetables were superior at east facing 4.5 m apart from Mahogany trees (0 1133 ) where, soil moisture was the highest. On an average the lowest yield per hectare (25.13, 26.56, 37.01 and 23.22 ton, respectively) of four leafy vegetables were observed at west facing 3.5 m apart from where the lowest soil moisture was observed and the soil temperature was comparatively higher.

Our farmers unknowingly and unconsciously practice agroforestry. Agroforestry adoption at farm level as well is at research level is still a swp behind practice in our country. Major focus of this study was to assess agriculturat university teachers' attitude towards agroforestry promotion in Bangladesh and also to explore relationship between each of the selected characteristics of agricultural university teachers and their attitude towards agroforestry , promotion in Bangladesh. Data were collected from 80 university teachers by face- to- face interviewing with the help of structural interview schedule during November 2013 to February 2014. Descriptive statistics were employed to describe the selected characteristics of the selected characteristics of the university teachers including their attitude towards agroforestry promotion in Bangladesh. Co-efficient of eorrclatiort was employed to explore the relationship between teachers' attitude towards agroforestry promotion and each of their selected characteristics. The findings revealed that overwhelming majority (91.250 /0) of the teachers had favorable attitude towards agroforestry promotion in Bangladesh. while rest of them had unfavorable or neutral attitude. The co-efficient of correlation shows that university teachers educational status, training experience and participation in seminar, symposium, conferences. workshops etc. had positive significant relationship, white their age, teaching experience, daily use of internet and social participation had no significant relationship with their attitude towards agroforestry promotion in Bangladesh.

The study was conducted in Savar Upazila under Dhaka district. Data were collected through simple randoni sampling method from 30 nursery owners out of 120 owners in Savar Upazila under Dhaka district. Selected nursery osiiers were interviewed face-to-face by researcher herselil Twelve problems were identified in seedling production. Scale score was used to determine nursery owners ' problem in seedling production while a problem faced Index (PH) was used to make comparison among the 12 selccted problems. Pearson's Product Moment Correlation coefficient (r) was used for the statistical analysis. Three fourth (76.7 percent) of' the nursery owners were faced medium to high problem while 23.3 percent faced little problem in seedling production. The findings also revealed that training exposure. annual income, marketing fhcility. capital investment, input availability and organizational participation had negative significant relationships with their problem faced in seedling production. According to problem faced Index (PH) lack of suitable area for seedling production ranked first followed by lack of technical knowledgc. lack oI'skilled labour, disease infestation and insect infestation.

The aim of the study was to select best summer vegetables, suitable for inclusion under shade condition in agroforestry systems. The selected vegetables were also grown in control i.e., open field condition. The vegetables were Indian Spinach, Stem Amaranth, Kangkong, Okra, Eggplant and Chilli and treatments were (a) T vegetables under full sunlight and (b) T iii shade sun = planting summer = planting summer vegetables under shade condition (reduced light intensity). The experiment was laid out following single factor RCBD design. Three replications were used for each treatment for each crop. During the study period maximum light intensity reduction was recorded in Chilli (42.2%) and minimum light intensity was reduced in case of Indian Spinach (22%) under shade. The shade had substantial effects on various growth parameters of the summer vegetables. From the experiment, significant result was observed in all morphological characteristics for all vegetables except Chilli under reduced light. Apart from this, highest yield was found in Kangkong (18.67 ton/ha) and Okra (22.54 ton/ha) in reduced light condition. Highest yield of Indian Spinach (8.93 ton/ha), Stem Amaranth (27.67 ton/ha), Eggplant (22.63 ton/ha) and Chilli (8.06 ton/ha) was recorded under full sunlight. Considering shade condition, Kangkong and Okra were best suitable for growing in Agroforestry systems.
