Abstract


The objective of present study was to compare the effects of vermicompost and chemical fertilizer on the growth and yield of crop plants in field conditions. Water hyacinth, high yielding rice husk, leaf litter and sewage sludge are major organic wastes that environmental problems. For their biodegradation, Eisenia. fetida was used to convert above wastes into valuable compost. The vermicompost of water hyacinth had minimal C: N ratio (12.4) followed, in increasing order, by sewage sludge (19.4), rice husk (23.6) and leaf litter (26.7).Then a field experiment was conducted to determine the relative efficacy of vermicompost (formed from water hyacinth) and inorganic fertilizer (urea) on various growth and yield parameters of chilli (Capsicum annuam) , brinjal (Solanum melongena) and tomato (Lycopersicon exculentum). The vegetable crop plants were grown separately in plots as per recommended agronomical practices .The growth parameters were recorded viz. height of plants, diameter of main stem, dry weight of whole plant (except fruit and roots), number of fruits per plant and total weight of fruits per plant. Farm Yard Manure @ 12.5 t/ha + vermicompost @8.33 t/ha gave the best results in terms plant height, diameter of main stem, dry weight of whole plant (except fruit and roots), number and total weight of fruits per plant followed by vermicompost @ 16.67 t/ha, NPK @ recommended dose and FYM @ 25 t/ha.

Key words : Organic waste, Vermicompost, Eisenia foetida, Inorganic fertilizer
