Abstract
Total N, P, K contents of pressmud vermicasts produced by mono and polyculture of earthworms show that N is enhanced 2-3 times, P. 1.3 - 1.6 times and K 1.9 -2.8 times in the casts of individual as well as casts of polyculture. Casts produced by Eudrilus eugeniae followed by polyculture are the most efficient ways of vermicomposting pressmud.
