What we do?

Journal of Research in Ecology is an international journal that publishes research studies in ecology and its relative area. The motto of this journal is to disseminate the idea of ecological research all around the globe and to maintain the manuscript processing time and charge as low as possible. The research articles on acceptance are published in the Journal (Both hard and soft copy) allows free access to the articles to disseminate rapidly among the researchers. Journal of Research in Ecology offers quality publication schedule with at least three peer- reviews. Our board of editors and peer - reviewers follow standards set by the Council of Biological Editors (CBE)

Capacity of fly ash and organic additives to support adequate earthworm biomass for large scale vermicompost production

Abstract:
To investigate the feasibility of utilization of vermiculture technology for large scale production of vermicompost from Fly Ash (FA) mixed with Press Mud (PM), Cow Dung (CD) and Crop Residue (CR) employing earthworms Eudrilus eugeniae and Lampito mauritii. Eight treatments namely FA alone (T1), 1 part FA: 1part CD (T2), 1 part FA: 1part PM (T3), FA: 1 part FA: 1part CR (T4), 1 part FA: 1part CD: 1part PM (T5), 1 part FA: 1part CD: 1part CR (T6), 1 part FA: 1part PM: 1part CR (T7) and 1 part FA: 1part CD: 1part PM: 1part CR (T8) were run under laboratory conditions. The growth and reproduction of earthworms in terms of biomass gain, cocoon and hatchlings production were measured at the end of experimentation. The data revealed that earthworms were unable to survive in 100% FA (T1) treatment. However, Maximum worm biomass was observed in T5 treatment than other treatments. Maximum cocoons and hatchlings production were also recorded in T5 treatment for both species of worms. This study clearly indicates that fly ash amended with press mud and cow dung in 1:1:1 ratio had no adverse effect on the growth and reproduction of E.eugeniae and L.mauritii as well as large scale vermicompost production.
