An experiment was carried out at Char Sadipur near Pabna town during August to February, 2015 to evaluate
the growing performance of two winter vegetables grown under Telsur (Hopea odorata) saplings. The
vegetables were stem amaranth (Amaranthus lividus) and red amaranth (Amaranthus gangeticus). Each
vegetable were laid out using the Randomized Complete Block Design (RCBD) with three replications as
separate experiment. In each experiment vegetables are grown at different distance from tree base which were
treated as different treatment. Performance of winter vegetables in terms of morphological parameters as well
as fresh and dry yield was affected significantly by distance from the tree. The result showed that vegetable
production was the highest recorded in control treatment which was significantly similar with 2, 3 and 4 feet
distance from the tree base and the lowest was observed less than 1 feet distance. Among the different
morphological characteristics of winter vegetable, stem girth, fresh weight and dry weight decreased
consistently with the decrease of distance from sapling where the best result was obtained under 4 feet
distance from Telsur sapling.
Key words: Performance, telsur, vegetables.
The actual forest area of Bangladesh is approximately 17.50% (BBS, 2004). But in order to enjoy the
benefits of nature, at least 25 percent of our land area must be covered with forest. Again, human nutrition
is very essential to develop a nation in every way. Vegetables can play a crucial role in this. In general,
vegetables are rich sources of minerals, vitamins and essential amino acids. A few techniques have recently
been advocated to overcome the future food challenges and confirming the environmental benefits,
Agroforestry in one of them. Agroforestry, the integration of tree and crop or vegetable on the same piece
of land, is a promising production system for maximizing yield and maintaining a friendly environment
(Nair, 1990). Telsur is a forest plant species from the Dipterocarpaceae family. It is found in Bangladesh,
Cambodia, India, Laos, Malaysia, Myanmar, Thailand and Vietnam. It is a large tree that grows up to 45 m
high and the base of the trunk reaches a diameter of 4.5 m. It grows in forests, preferably near rivers, at
altitudes between 0 and 600 m. Valued for its wood, it is an endangered species in its natural habitat
(IUCN, 2006). Vegetable cultivation under Telsur provides both the demand for wood and for human food.
To increase overall production, the current study was therefore conducted with the aim of evaluating the
performance of important vegetables grown under Telsur tree, to identify the appropriate Agroforestry
system for maximum land use in Bangladesh.
Materials and Methods
The study was made to evaluate the performance of vegetables in association with sapling of telsur timber
species. The soil of the experimental area was a medium high land. The texture of the soil was silty loam
having pH 6.7 (Amir and Bhuiya, 1994). The topography of the field was medium high land above flood
level. The vegetables were stem amaranth (Amaranthus lividus) and red amaranth (Amaranthus
gangeticus). Randomized Complete Block Design (RCBD) with three replications as separate was
