Biodegradation of Agricultural Residues and Oily Waste, Their Effect on Vegetable Crop Yield

Biodegradation is the breakdown or transformation of chemical substances by microorganisms using substance as a carbon source or energy source. Biodegradation means decomposition of agricultural residues and oily waste carried out. Where the nitrogen content was increased from 75 % to 1.23 % in 100 % agricultural compost and positive effect of oily waste was the requirement of extra humidity due to the hydrophobic property of the specific waste. Agricultural residues and oily waste act as a bulking agent which can be decomposed by cow manure for composting. Compost is the secret ingredient that allows bacteria to work having some kind of growth medium which require to micro-organisms. Composting is the enrichment technique adopted by two method aerobic and anaerobic composting seven treatment in each method. Aerobic and anaerobic composting requires 120 days and 150 days for degrading respectively. As the less time period and to avoid the problem of odor we adopted method of aerobic composting. the effect of compost in the field trial results of spinach crop could be experimented. Field trial experiment carryout by duplicate method because effect of soil, effect of bioinoculum and the method of composting affect production of crop.
