Abstract/ Executive Summary:

A study on seedling growth of three important timber trees viz. sissoo (Dalbergia sissoo), arjun (Terminalia arjuna) and bokain (Melia sempervirens) in three agro ecologically different area was carried out during 2003. Three agro-ecologically different areas are namely Mymensingh (Old Brahmaputra Floodplain, AEZ 09), Bagerhat (Low Ganges River Floodplain, AEZ 12) and Pirojpur district (Ganges Tidal Floodplain, AEZ 13). The aim of the experiment was to investigate the growth behavior of selected timber seedling in different area of Bangladesh and find out the best side (district) where the specific timber seedling grows well. Data collection was started on 20 June, 2003 and completed on 20 July, 2003. Data on height, base diameter, fresh weight and dry weight was taken. Soil and climate of different region influenced the growth of seedlings significantly. The three timber species viz. sissoo (Dalbergia sissoo), arjun (Terminalia arjuna), bokain (Melia sempervirens) seedling showed highest growth performance in Mymensingh district and the medium performance in Pirojpur district. The Seedling of Bagerhat district showed poor growth performance than Mymensingh and Pirojpur district.

Keywords: Timber seedlings, Growth, Region

Location: Nine nurseries comprising three from each of Trishal upazilla in Mymensingh district, Morrelgonj upazilla in Bagerhat district and Sarupkathi upazilla in Pirojpur district

Start Date: 20-06-2003

End Date: 20-07-2003

Program Area: Seed Technology

Commodity: Seedling

Objectives:

1. To investigate the growth behavior of important timber seedling in different studied area in Bangladesh and find out the best site (district) where specific important timber seedlings grow well.

Methodology:

The experiment was conducted at nine nurseries comprising three from each of Trishal upazilla in Mymensingh district, Morrelgonj upazilla in Bagerhat district and Sarupkathi upazilla in Pirojpur district. The sites were selected on the basis of the availability of nursery. In each nursery of each district, three species of different ages (three months, eight months and twelve months) timber seedlings namely sissoo (Dalbergia sissoo), arjun (Terminalia arjuna), bokain (Melia sempervirens) were selected by random sampling. Data on height, base diameter, fresh weight and dry weight was taken for each selected species. Height and base diameter was measured from standing seedlings in nursery. Then seedling species of different ages were collected from each selected nursery of the respective upazilla and taken fresh weight by balance. The collected samples were dried in sun light over a period of one month and dry weight was taken in the laboratory of Agroforestry Department, Bangladesh Agricultural University, Mymensingh. The time of sowing and age of seedling was recorded from respective nursery owner. Data were collected from 20 June, 2003 to 20 July, 2003. Data on various growth parameters under the study were analyzed statistically by using MSTATC program. The mean differences were evaluated by least significant difference test (LSD).The physical properties of soil of three districts were different. The soil of Mymensingh district except some minor areas of hill in the northern border is formed with recent and sub-recent alluvial sediments. The soil of Trisal upazilla belongs to Mymensingh was same. The soil of Bagerhat district was mainly non calcareous clay, but the working upazilla, Morrelgonj under the same district was highly saline tidal clay. The soil of northern part of the Pirojpur district was non saline, tidal silty clay while the soil of southern part was poorly drained, tidal clay of the old Lower Meghna Tidal Floodplain. The soil of Sarupkhati, the representative upazilla of Pirojpur was non saline, tidal and silty clay.

Achievement/Findings:

The three timber species viz. sissoo (Dalbergia sissoo), arjun (Terminalia arjuna), bokain (Melia sempervirens) seedling showed highest growth performance in Mymensingh district and the medium performance in Pirojpur district. The Seedling of Bagerhat district showed poor growth performance than Mymensingh and Pirojpur district.
