The term ‘garbage’ used internationally to describe waste materials arising from domestic, trade, commercial, industrial, agricultural and other related activities and from public services. It has created a real threat not only to the living environment but also for the cultivation of crops as well as afforestation. The present investigation was conducted to study the influence of two weeks decayed or stored waste materials as component potting media on the growth and vigour of Ailanthus triphysa seedlings. The survival rate was ranged from 95 to 100 per cent among various treatments studied. Mixture of soil, partially decayed tea waste and sand was recorded the maximum height in nursery and T2 [Soil: partially decayed Municipal waste (1:1)] recorded maximum girth. With regards to height, the maximum performance (84.00 cm) was registered in mixture of soil, sand and cowdung and maximum collar diameter was reported in soil, partly decayed tea waste and sand (T7) in sapling level. Height increment at nursery level after eighth month showed the maximum increase was in T7 (21.27 per cent) and diameter increment 7.91 per cent in T2 as compared to the control (T1). Maximum increment per cent in the plantation was recorded in T7 (-3.08) and T5 (11.43) for height and diameter respectively at sapling level. The combined use of soil with garbage result in the production high quality planting material and the effect of plantation development were very less.
