Agricultural University, Vellanikkara, Thrissur to evaluate the effect of potting
media containing garbage on the growth and vigour of teak (Tectana grandis Linn.
F.) and mangiurn (Acacia mangium Willd) seedlings. The study revealed that when
garbage, especially fresh garbage, was used as a component of potting media, no
significant effect was observed on survival rate of seedlings of teak, but a high rate
of mortality was observed in the case of mangium.
The potting media containing soil, sand and cow dung in equal
proportions produced the best results with regard to shoot growth parameters like
height and girth. However, the potting media containing soil, sand and one month
decomposed garbage also produced similar results which was on par with the best
treatment. Teak seedlings registered higher root biomass, root spread and root
number when grown in the media containing garbage especially one month
decomposed garbage. Unlike teak, in the case of mangium the treatment soil, sand
and cow dung in equal proportions was proved to be the best with regard to root
growth parameters.
In both teak and mangium, chlorophyll content was not found to be
significantly influenced by any media. Seedlings grown in the media containing
soil, sand and cow dung in equal proportions recorded higher uptake and
concentration of nitrogen, phosphorus and potassium in the plant tissue when
compared to all other treatments. This was true both ill the case of teak and
mangrurn.
In general, the treatments T3 (soil: sand: cow dung) and T6 (soil: sand:
1 month decomposed garbage) were proved to be better when compared to all
other treatments. In many cases these two treatments were found to be on par.
