Abstract

Epigeic earthworm, Perionyx excavatus were cultured on a variety of organic wastes amended with cattle manure in different seasons to know the influence of different organic waste-diets and seasonal environmental factors on life activities of epigeic earthworm, Perionyx excavatus. Results showed that growth and reproductive strategies of P. excavatus varied with different organic waste-diets and seasons. Growth, maturity and reproduction of worms in all waste-diets were significantly more during monsoon followed by winter and summer seasons. All agricultural and garden organic wastes served as a source of balanced diet for this worm during all three seasons. Further, mixed organic waste and soft (straw-based) wastes appeared more congenial for overall life activities of this worm than that of hard (pod-based) wastes (P<0.001, P< 0.05). ?
