Eluavation of Earthworm (Perionyx excavatus) Growth Raised in Different Cultures

Abstract

The present experiment was carried out at households in Cam Hoang commune, Cam Giang district, Hai Duong province to determine growth of earthworms raised in 3 types of cultures: Formula 1: 70% pig manure + 30% banana trunk (composted)); Formula 2: 60% pig manure + 20% pig manure + 20% banana trunk (composted); and Formula 3: 50% cow manure + 50% pig manure (composted). Results show that after 60 days of experiment earthworms developed well with the culture 1 (the biomass increased more than 3.6 times for the first batch and 2.45 times for the second batch,) followed by culture 2 (the biomass increased more than 3.48 times for the first batch and 2.17  times for the second batch, and the last was culture 3 (the biomass increased more than 2.85 times for the first batch and 2.06  times for the second batch
