AZIZ, TANJILAL
The experiment was conducted at Central farm of Sher-e-Bangla Agricultural University,
Sher-e-Bangla Nagar, Dhaka, Bangladesh to screening of some leafy vegetables under
mahogany tree based agroforestry system. 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.

MEHEDY, SIJBARNA
Agroforcstrv is a new approach in our country. although it has been being
practiced in the tropics from decades. 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.

HEERA, IFFAT JAHAN
The objective of the study was to determine the problem faced by the nursery
owners in seedling production and also to explore the relationships between the
selected characteristics of the nursery owners and their problem faced in seedling
production. 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.

A field experiment was conducted at Central farm of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during the
period from March, 2014 to June, 2014. 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

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.
