Dynamics of nutrients and microflora during vermicomposting of mango leaf litter (Mangifera indica) using Perionyx ceylanensis
Pre-decomposed (15 days) mango leaf litter with cowdung in 50:50 (wt/wt) was subjected to vermicomposting using Perionyx ceylanensis for 60 days. The electrical conductivity, total NPK, Ca, Na and other nutrients were higher in the vermicompost than in the worm unworked control substrate, whereas organic carbon and C/N ratio were lowered. The population of bacteria, fungi and actinomycetes at the ...

Potential of Eisenia fetida for vermicomposting of garden trimmings spiked with cow dung
The garden residues and trimmings were vermicomposted in order to mitigate environmental problems caused by them. The results of experiments indicated that the addition of Garden Trimmings (GT) up to 30% with cow dung (CD) produced good quality vermicompost in terms of increased NPK status as well as decrease in C : N and C : P ratio. A comparison of the decomposition of GT + CD in ...

Vermicomposting of solid textile mill sludge spiked with cow dung and horse dung: a pilot-scale study
This paper reports the vermicomposting of Solid Textile Mill Sludge (STMS) spiked with Cow Dung (CD) and Horse Dung (HD) in a six-month pilot-scale experiment employing Eisenia foetida. Growth and fecundity of Eisenia foetida were significantly affected by temperature variations. The lesser number of cocoons and hatchlings were produced in pilot scale experiments than in controlled temperature ...

Process parameters analysis for the vermicomposting of shredded paper using Pheretimoid Spp.
This study was to assess the effect of new species of earthworms, Pheretimoid Spp., on vermicomposting and compare the quality of vermicompost against compost produced from the same mix ratio of shredded office paper (SOP) together with grass clippings (GC) and cow manure (CM). Two composting experiments were setup in rotary drum composters namely: 1) composting of SOP, GC and CM followed by ...

Effect of poultry waste on vermicomposting of anaerobically digested cattle dung slurry
This study was conducted to explore the effect of poultry waste (PW) on the vermicomposting of anaerobically digested cattle dung slurry (CDS) using Eisenia fetida worm species. A total of three vermicomposting beds, having different percentage of PW and CDS were established (100% CDS; 75% CDS + 25% PW; 50% CDS + 50% PW). At the end of experiment vermicompost showed a higher concentration of ...

Vermicomposting technology: an efficient biological processing of obnoxious weed water hyacinth (Eichhornia crassipes)
The present work was carried out during the year 2009–2011 to study the physicochemical and microbial analysis of both vermicompost and vermiwash produced from two treatments of water hyacinth: T1: 100% water hyacinth + 5% soil, T2: water hyacinth + cow dung (50% + 50%) by using earthworm species, Eudrilus eugeniae for a period of 90 days. The nutrient values along with microbial count of ...

Vermicomposting of mustard residue and effect of its application on soil and plant nutrients status
Vermicomposting of mustard (Brassica juncea) residue with pretreatments of submergence in water, nutrients (urea and low grade rock phosphate) supplementation, microbial (Bacillus sp., Trichoderma viride and Cellulomonas fimi) inoculation and their combined use with fresh cow dung/slurry improved the quality of vermicomposts with respect to C/N ratio, yield, humus fractions and nutrients content. ...

Vermiculture for sustainable horticulture agronomic impact studies of earthworms, cow dung compost and vermicompost vis-a-vis chemical fertilisers on growth and yield of lady's finger (Abelmoschus esculentus)
Pot experiment was conducted to assess the performance of live earthworms and vermicompost on growth and yield of lady's finger (Abelmoschus esculentus). Among the various treatments, live earthworm + cattle dung (as feed), cow dung compost, vermicompost, chemical fertiliser and control were organised. The results indicated that all growth and yield parameters were found superior and ...

Biodegradation of water hyacinth, sugarcane bagasse and rice husk through vermicomposting
Water hyacinth, sugarcane bagasse and rice husk are major bio-organic wastes causing severe environmental problems. For their biodegradation, Eisenia fetida was used as a vermicomposting worm in outdoor open field conditions. The above wastes were mixed separately with fresh cow dung in the ratio 1 : 5 (by weight). The mixtures were vermicomposted for 90 days in pits of size 2 × 0.5 × 0.6 m (l × ...

Application of two vermicomposts on a Rice crop: Effects on soil biological properties and rice quality and yield
Vermicomposts have been considered as a soil additive to reduce the use of mineral fertilizers because they provide required nutrients, increase cation exchange capacity, and improve water-holding capacity. However, the effect of each vermicompost on soil properties and crop yield depends on its chemical composition. The main objective of this work was to study the effect of incorporating two ...

Agronomic impact of earthworms, cow dung compost, vermicompost and chemical fertilisers on growth and yield of brinjal ( Solanum melongena )
The pot experiment was conducted to assess the impact of live earthworm + cattle dung (as feed), cow dung compost, vermicompost, chemical fertilisers and control (without fertiliser) on growth and yield of brinjal (S. melongena). Growth and yield parameters were significantly superior in the pots treated with live earthworms as compared to other fertiliser inputs at 5% level. The plant height ...

Growth and reproduction of Eisenia foetida in various industry waste sludge during vermicomposting: a laboratory investigation
The effect of industrial waste sludge on growth and reproduction on earthworm Eisenia foetida was studied. Earthworms, cow-dung and soil were collected from local farm, and industrial waste sludge from industries – United Phosphorus Ltd. (UPL), Enviro Technology Ltd. (ETL), Deepak Dye Industry (DDI) and Doshi Ion Industry (DII). Chemical properties, biomass gain, natality and hatchling of E. ...

Improved performance of red worms (Eisenia andrei) in compost of cattle manure rinsed with water
To achieve satisfactory results with vermiculture, it is important to know how many times to rinse cattle manure to eliminate salts. Treatments under evaluation were 0, 1, 2, 3, 4, 5, 6 or 7 rinses in a tap water: manure ratio of 1 : 1 (v/v). Electrical Conductivity (EC), Biomass of Worms (BW) and Number of Cocoons (NC) were evaluated. The EC ranged from 2.57 to 0.5 dS·m−1 for T0 and T4. ...
