Effect of tertiary combinations of animal dung with agrowastes on the growth and development of earthworm Eisenia fetida during organic waste management

Abstract

Purpose Improving the nutritional value of rice straw by microbial inoculants and some physical treatments for animal feeding during dry seasons. Methods Different microbial inoculants and some physical treatments were used to improve the nutritional value of rice straw. Rice straw was divided into moist straw, soaked straw for 24 h without pasteurization and soaked for 24 h and pasteurized at 100 °C/1 h, and all of them were inoculated with different microbial inoculants. Results Moistened rice straw inoculated with Azotobacter chroococcum and Saccharomyces cerevisiae recorded the highest significant reduction in organic matter percent, 74.21%. The highest significant reductions in crude fiber, neutral detergent fiber, and acid detergent fiber percent were recorded in moistened rice straw inoculated with Azospirillum brasilense and Saccharomyces cerevisiae which gave 27.54, 55.39 and 42.47%, respectively. The highest significant increase in crude protein percent, 13.71%, was recorded in rice straw soaked for 24 h and inoculated with Azospirillum brasilense and Bacillus megaterium. The combined interaction between microbial treatments and physical pretreatments of rice straw gave a significant decrease in organic matter, crude fiber, neutral detergent fiber and acid detergent fiber %, as well as a significant increase in crude protein % compared to control. Addition of nitrogen fixers to rice straw improved its nitrogen contents. Conclusions This study showed the possibility of improving the nutritional value of rice straw using microbial inoculants and some physical treatments to produce safe and cheap animal feeds.

Vermicomposting of different organic materials using the epigeic earthworm Eisenia foetida

“…Today vermicompost is an important component of organic farming systems, because it is easy to prepare, has excellent properties and is harmless to plants. Vermicompost improves the physical, chemical and biological properties of the soil as well contributes to organic enrichment (Ansari and Jaikishun 2011;Chauhan and Singh 2013). In 1996 the Ministry of Agriculture, Animal Husbandry and Fisheries (LVV) in Suriname made an attempt to investigate vermicomposting, but did not achieve significant results (Nanden and Dipotaroeno 1996).…”

Quality assessment of the physicochemical properties of vermiwash produced from different sources during successive storage periods

“…The decreased EC may mean that the amount of available soluble solids such as salts (ions) may be low in the vermiwash samples. A decrease in EC may be due to the increased rate of loss of organic matter, consequently release of different minerals salts (Chauhan and Singh 2012).…”

“…These metabolites enhanced the enrichment of the vermiwash with exchangeable potassium. The decreased in potassium in T2 and T4 may be as a result of leaching of this soluble element after water was applied for collection (Ansari and Rajpersaud 2012;Chauhan and Singh 2012;Degefe et al 2012).…”

Studies on the Integrated Aquaponic System with Green Herbal Cultivation by using Liquid Fertilizer of Seaweed, Turbinaria Conoides

“…Vermicompost was used in the present study was obtained by utilizing the African earthworm, Eudrilus eugeniae prepared as detailed by (Chauhan and Singh, 2013). The earthworm was bought in the vermicompost form of uniform size were selected at Pannimadai near Thudiyalur, Coimbatore, Tamil Nadu.…”
