Abstract/ Executive Summary:

Seedling growth of four multipurpose tree species (MPTs) were evaluated in four different types of container up to six months in nursery condition at Department of Agroforestry and Environment, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh. The MPTs were Gliricidia sepium, Delonix regia, Terminalia arjuna and Swietenia mahagoni and containers were gunny bag, poly bag, earthen pot and bare rooted. The first two species were leguminous and the rest two were non-leguminous. Seedling height (cm), collar diameter (mm), leaf number and fresh and dry weight (gm) of root, stem and leaf was measured to compare the growth performance of the tree species. Leguminous species showed better growth performance than the non-legume species. G. sepium performed better than the other three species in terms of plant height, collar diameter, and biomass production. Statistically significant and maximum leaf number was recorded in T. arjuna followed by G. sepium, D. regia and S. mahagoni. Gunny bag produced maximum biomass for all the studied tree species.

Objectives:

1. To compare the growth performance of aforementioned four Multi-purpose tree species (MPTs) in different containers under nursery conditions.

Methodology:

The experiment was carried out over a period of six months from May to October, 2012 in the nursery of the Department of Agroforestry and Environment, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh. The experiment was laid out in two factors Randomized Complete Block Design (RCBD) with three replications. Factor 1: Four different types of container i.e. poly bag, gunny bag, earthen pot and bare rooted. Factor 2: Four Multipurpose tree species i.e. Gliricidia sepium, Delonix regia, Terminalia arjuna and Swietenia mahagoni. Potting soils were prepared as Cowdung : Soil = 1: 2 ratio and the size of different containers were 23 cm × 15 cm or 9 inch × 6 inch for each. The soil was sieved by 2 mm to remove stones, roots and other debris. In total 120 poly bags, 120 gunny bags, 120 earthen pots and 120 pit for bare rooted were prepared and placed in a RCBD. Healthy seeds for each tree species were collected from plus trees of BSMRAU farm. The seeds were treated with hot water for 3 minute followed by soaking in cold water for 12 hrs to enhance germination. After treatment three seeds were sown per container. After germination one healthy seedling was kept. Adequate watering and care was taken regularly. Data for seedling height, collar diameter and leaf number was recorded at the age of 1.5 months, 3 months and 6 months. Height was measured with a steel scale (1.5 m) marked in meters and centimeters. In case of multi-stemmed and shrubby seedling, only the height of the tallest shoot was recorded. And collar diameter was measured by taking the mean of two readings with calipers. At 6 months three seedlings of each type of container and each tree species were harvested randomly for recording the biomass productivity (both fresh weight and dry weight of root, shoot and leaf including the above mentioned parameters. After uprooting the root was washed with tap water to remove soil particles and dried by soaking with tissue paper. Fresh weight for root, stem and leaf was measured immediately after harvest and kept in desiccators for 72 hrs and then dry weight data was recorded. Plant height, collar diameter and biomass weight was measured in centimeter (cm), millimeter (mm) and gram (gm), respectively. The data were subjected to analysis of variance to test for significant difference in different parameters among the species studied. The means were compared using the Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

The MPTs were Gliricidia sepium, Delonix regia, Terminalia arjuna and Swietenia mahagoni and containers were gunny bag, poly bag, earthen pot and bare rooted. The first two species were leguminous and the rest two were non-leguminous. Seedling height (cm), collar diameter (mm), leaf number and fresh and dry weight (gm) of root, stem and leaf was measured to compare the growth performance of the tree species. Leguminous species showed better growth performance than the non-legume species. G. sepium performed better than the other three species in terms of plant height, collar diameter, and biomass production. Statistically significant and maximum leaf number was recorded in T. arjuna followed by G. sepium, D. regia and S. mahagoni. Gunny bag produced maximum biomass for all the studied tree species.
