Decomposition of poultry litter through vermicomposting using earthworm Drawida sulcata and its effect on plant growth

Efficiency of cow dung based vermi-compost on seed germination and plant growth parameters of Tagetes erectus (Marigold)

“…(2014) . The pH of vermi-compost is very much essential because it affects the availability of nutrients in the soil ( Yuvaraj et al., 2018 ). At the beginning of the experiment, pH was increased as 8.6 but the reduction was recorded at the end of vermi-compost production as 7.8.…”

“…Increased nitrogen level may be attributed to the release of nitrogenous products of earthworm metabolism through the casts (excreta), urine, as well as mucoproteins. We agreed on the outcomes of Yuvaraj et al. (2018) and Li et al.…”

“…They reported that C:N less than 12 is preferable for agricultural purposes. The more reduction in the content of C/N ratio reflected efficient worm activity, leading to an accelerated rate of decomposition and mineralization, thereby resulting in high grade, nutrient-rich, good quality compost ( Yuvaraj et al., 2018 ).…”

“…Vermi-bed was prepared using moisten papers/shredded twigs/grass clippings/coconut peel, varying according to what is available locally. Cow dung was mixed with the pre-digested substrate in a 3:1 ratio ( Yuvaraj et al., 2018 ) and dumped into the constructed pits. At the beginning of vermi-composting 100 to 200 clitellate E. fetida were added and feed matter like wheat straw, cow dung, green leaves, crushed eggshells, brown leaves, and tea bags were given to E. fetida .…”

The influence of vermicomposting on photosynthetic activity and productivity of maize (Zea mays L.) crop under semi-arid climate

“…After processing, the material was mixed with FYM and soil. Twenty individuals of earthworm [ Eisenia fetida (Savigny, 1826)] were added into each pot and kept wet for twenty days [ 32 ]. The earthworms were discarded by following the sieve method and vermicompost was transferred to pots ( Table 2 ).…”
