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. ...

Earthworms helping economy, improving ecology and protecting health
Earthworms can treat organic garbage, livestock manure and poultry droppings and turn them into premium organic fertilisers, because humus only exists in earthworm feces and castings, compared with other fertilisers. Earthworms can also supply quality animal protein as feed, and offer the best raw materials for the biochemical and pharmaceutical industries. Vermiculture should be put into a whole ...

Vermicomposting of organic wastes using Eisenia foetida (Savigny)
An experiment was carried out in vermibeds to evaluate the suitability of organic wastes for vermicomposting using Eisenia foetida. The results indicate that nitrogen, phosphorus and potassium were maximum in the vermicompost formed from treatment T12, followed by T3. Calcium and sulphur were observed maximum in T3. T9 registered maximum magnesium content, followed by T8. There was also a ...

Environmental dimensions of fertilizer and pesticide use; relevance to Indian agriculture
This paper presents an overview of the environmental consequences of fertilizers and pesticides in agriculture and the measures needed to mitigate the adverse impact of these chemicals on environment. The issues are then analysed from the perspective of the use of fertilizers and pesticides in Indian agriculture. Fertilizer consumption in India is concentrated in about one-third of the cultivated ...

Vermicomposting of domestic waste by using two epigeic earthworms (Perionyx excavatus and Perionyx sansibaricus)
The composting potential of two epigeic earthworms (P. excavatus and P. sansibaricus) was studied in 2002 to breakdown the domestic waste under laboratory conditions. The experimental container with P. sansibaricus showed maximum mineralization and decomposition rate than that of P. excavatus. Except for exchangeable K (it was higher (P = 0.004) in a container with P. excavatus), the domestic ...

Does substrate quality affect earthworm growth and reproduction patterns in vermicomposting systems? A study using three popular composting earthworms
Efforts were made to evaluate the impact of substrate materials (crop residues + sheep manure, cowshed manure, and kitchen waste + leaf litter) on growth and reproduction performance of composting earthworms: Eudrilus eugeniae, Perionyx excavatus and Perionyx sansibaricus, under laboratory conditions. Results indicated that earthworm biomass and cocoon production rate was directly related to the ...

Vermicompost production and its use for crop production in the Philippines
Vermicompost was produced with Perionyx excavatus and Eudrilus eugeniae using animal manures, leguminous leaves, grass and agro-forestry wastes. Yields of corn fertilised with vermicompost at 5t/ha and rice at 2t/ha of vermicompost were comparable with those for corn fertilised with 100% chemical fertilisers and 40% increase over the control for rice. Chinese cabbage and eggplant fertilised with ...

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 ...

Developing value added bioactive timber waste vermicompost with addition of microbial inoculants
A study conducted at Vermiculture Research Station (VRS), Aligarh, to transform the timber solid waste vermicompost (TSWV) into bioactive compost with the addition of beneficial microbes has brought to light feasibility of a potential technique to develop value added quality product with higher agronomic value for the first–time. TSWV was inoculated with microbes Azotobacter chroococcum, Bacillus ...

Remediation of heavy metals from urban waste by vermicomposting using earthworms: Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus
This study revealed that three earthworm species, viz., Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus, through vermicomposting remediated heavy metals - Pb, Zn, Cd, Cu and Mn from the urban waste - organic fraction of Municipal Solid Waste [M(O)SW], vegetable Market Waste (MW) and Floral Waste (FW). The concentrations of Zn, Cd and Cu were 36.1, 50.9 and 70.2% higher in M(O)SW compared ...

A Rose by any other Name
Bohemian Flowers on the south shores of Lake Naivasha, Nakuru County, Kenya, is today one the largest rose and mixed flower farms, exporting blooms all over the world. Once owned by a member of the Happy Valley set, the estate was first established as a cattle ranch until a Dutch entrepreneur Hans Zwager acquired the estate in 1968 and started exploring opportunities in agribusiness with a small ...
