Abstract

Aim : To investigated the comparative effect of different potting media with different compositions on growth and vigour of Tectona grandis (Teak), Ailanthus triphysa (Matti) and Swietenia macrophylla (Mahogany) seedlings.

 

Methodology : To determine the effect of different following seven potting media were prepared by thoroughly mixing the following components viz. T1 - Soil: Sand : cow dung (1:1:1 ratio- control treatment); T2- Soil: Municipal waste (1:1); T3 - Soil: Coir waste (1:1); T4- Soil: Tea waste (1:1);T5 - Soil: Municipal waste: Sand (1:1:1); T6 - Soil: Coir waste : Sand (1:1:1) and T7 - Soil: Tea waste: Sand (1:1:1).Estimating the growth attributes, physiological parameters and nutrient content of different treatments of selected important timber species seedlings.

 

Results : Results indicated that T1, T7 and T2 as the best combination of potting media tomanifest maximum performance of various growths attributes for teak, mahogany and matti, respectively. Indeed, treatments containing municipal waste and cow dung recorded aslightly higher value of nitrogen, phosphorous and potassium content at the end of the study period.

 

Interpretation : There is a lack of scientific data, effect of municipal garbage on the growth and vigour of tree seedlings, either in the nursery or in the plantation. This information may be helpful in production of healthy seedling of different growth characters such as nutrient uptake, biomass production, chlorophyll production and leaf growth behavior of seedlings.
