Gliricidiasepium,Delonixregia, Swieteniamacrophylla and Terminaliaarjunaare important MPTs. There is a demand of these fast growing MPTs in any plantation programs all over the world. So, in recent years the interest for producing quality seedlings by improved and modern nursery technique has increased [1]. Various growth containers are used for growing this species in nursery conditions [2] and poly bags are widely used for its light weight, low price, durability and availability. This experiment was carried out to compare growth performance of aforementioned four multipurpose tree species under nursery conditions. Table 1: Seedling height, collar diameter and leaf number of four MPTs as influenced by growth containers In a column, figure having the similar letter (s) or without letter (s) do not differ significantly as per DMRT Materials and Methods The study was carried in the nursery of Bangabandhu Sheikh MujiburRahman Agricultural University (BSMRAU), Bangladesh from May to October, 2012. The experiment was used a RCBD sampling with three replications. The containers were poly bag, gunny bag, earthen pot and bare rooted. Tree species were Gliricidiasepium,Delonixregia, Swieteniamacrophylla and Terminaliaarjuna. Potting soils were prepared as cowdung:soil = 1:2 and container size was 23cm ×15cm for each [3]. Healthy seeds for each tree species were collected from BSMRAU farm and then treated with hot water for 3 minutes followed by soaking in cold water for 12 hrs. 3 seeds were sown per container. After germination 1 healthy seedling was kept. Data for seedling ht (cm), collar diameter (mm) and leaf number was recorded. Root, stem and leaf fresh and dry weight was measured for biomass study. Data were analyzed by using MSTAT software and the means were compared using the Duncan’s Multiple Range Test (DMRT). Conclusions • G sepium performed better in terms of plant height, collar diameter, and biomass production followed by D regia, T arjuna and S mahagoni. • Gunny bag produced maximum biomass for all the treatments. However earthen pots performance was poor for all the species and all the sampling dates. • For local plantation program seedlings can be grown in gunny bag instead of poly bag.
