Abstract
A laboratory experiment was conducted to decompose the amoora fruit husk enriched
with amoora de-oiled cake as a source of N and di-ammonium phosphate as a source of P with
inoculation of a microbial consortium (Trichoderma viridae, Phanaerochyte crysosporium and
Trichurus spiralis) for rapid composting. The effect of thus enriched bio-compost on the growth
of tomato plants in pot culture was also assessed. The initial C: N ratio of the substrate was 85:1
which got reduced to 12.3: 1 in treatment with amoora fruit husk + microbial Consortium+ diammonium
phosphate and de-oiled cake satisfying the degree of compost maturity. The compost
contained higher amounts of N (1.94%), P (1.58%) and K (1.43%) in treatment with amoora
fruit husk + microbial consortium + de-oiled cake and was found to enhance the total height of
plant, number of leaves, number of branches, internodal length, dry weight and fresh weight and
total biomass of the tomato plants. The treatment with amoora fruit husk + microbial consortium
+ de-oiled cake + di-ammonium phosphate recorded significantly higher in terms of mass loss,
NPK content and C: N. The treatment with amoora fruit husk + microbial consortium + deoiled
cake was also on par with the treatment amoora fruit husk + microbial consortium+ diammonium
phosphate and de-oiled cake indicating that in the presence of oil cake as a source of
N, microbial consortium can bring about faster decomposition of amoora fruit husk organically
and also can influence the plant growth.
