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.
