Abstract. Islam MDA, Rahman MDA, Hossain MK. 2019. Effect of container and potting media on raising quality seedlings of Acacia auriculiformis in the nursery. Asian J Agric 3: 26-32. The study elucidates the effect of container and potting media on raising quality seedlings of Acacia auriculiformis in the nursery of the Institute of Forestry and Environmental Sciences, University of Chittagong to find out a suitable container and potting media for raising large scale quality seedlings. The seedlings were evaluated by five container and seven potting media treatments for eight months. A Completely Randomized Block Design (CRBD) was adopted for the study with three replications for each treatment. The Analysis of variance (ANOVA) and Duncan’s Multiple Range Test (DMRT) was tested for the analysis to explore the possible treatment variations. However, the study reveals nodulation with growth parameters; shoot and root dry biomass production and quality index were highest in 20 cm × 15 cm size polybags whereas the highest root length and shoot-root ratio was observed in 15 cm × 10 cm and 15 cm × 13 cm size polybag respectively. Considering the potting media, highest nodulation, growth parameters, shoot dry and fresh weight, shoot- root ratio and biomass were found in combination of soil + cow dung + phosphorus (0.16 g/polybag). Highest root length, root fresh and dry weight, and quality index were found in the combination of soil + cow dung (3:1). Therefore, it is recommended that containers of 20 cm × 15 cm size polybag and with a potting media of soil + cow dung + phosphorus (3 parts soil, 1 parts cow dung + 0.16 g/polybag) combination produce quality A. auriculiformis seedlings in the nursery.

Growth and quality of Geronggang (Cratoxylum arborescens) seedling in different types of growing mediums and containers

“…This was a common result due to the available of nutrient, water and space was higher in bigger container, and therefore will drive to increase the growth rate of seedling. This fact was agree to the several previous studies in other tree species such as Acacia nilotica, Terminalia bellirica A. auriculiformis and Cyclocarya paliurus [11], [12], [20], [21].…”

“…The part of seedling production technology is about the selection of growing medium and its containers. These parts is important due to could determine the growth and quality of seedling and the required time to obtain the plantable seedling [10][11][12].…”

Effect of Potting Tube Size on Growth and Development of Zizyphus mauritiana Seedlings

“…The longest primary root (31.07 cm), maximum number of secondary roots (100.72), and fresh root weight (17.55 g) was in the 4200 CC container (polybag 23 cm x 28 cm) which was statistically superior to remaining container sizes (Kishor & Ram, 2019). Another study by Islam et al (2019) indicated that the longest shoot length (137.5 cm), root length (38.1 cm), and collar diameter (9.5 mm) were highest in T4 treatment which had the largest potting tube size (20 x 25 cm). Studies have shown that soil fertility and water retention are also positively correlated with potting tube size (Islam et al, 2019).…”

Studies have shown that soil fertility and water retention are also positively correlated with potting tube size (Islam et al, 2019). A study by Agonafer et al, (2016) found that larger pots retained more water than smaller ones; this has important implications for seedlings development in drylands, where water is scarce.…”

Effects of Growing Media and Biocapsules on Germination and Growth of Papaya (Carica papaya) cv. Pusa Nanha

“…The use of suitable growing media or substrates for sowing of seeds directly affects the germination, development and functional rooting system. A good growing medium provides sufficient anchorage or support to the plant, serves as reservoir for nutrients and water, allow oxygen diffusion to the roots and permit gaseous exchange between the root and atmosphere outside the root substratem [7][8][9][10]. The quality of seedlings is very much influenced by growing media under nursery.The quality of seedlings obtained from a nursery influences reestablishment in the field and the eventual productivity of an orchard [11].…”
