Endangered Medicinal Plants of Temperate Regions: Conservation and Maintenance
Published in Amit Baran Sharangi, K. V. Peter, Medicinal Plants, 2023
Various treatments on nutrient use aspect revealed that plant height, leaf length was more with vermicompost (@0.50 t/ha), and statistically better to rest of the nutrient doses (Table 9.3). Leaf breadth was more with leaf manure (@0.50 t/ha), and gave notable reply compare to other application of organic nutrient supply except vermicompost (@0.50 t/ha). The number of leaves/plant record with vermicompost (@ 0.50 t/ha), was statistically better than others (Table 9.3). The highest petiole length was observed with leaf manure (@0.50 t/ha) and was at par with vermicom-post (@0.50 t/ha). The number of flowers/plants was more with the FYM (@0 50 t/ha), and similar to the vermicompost used field. The number of follicles and rhizome girth, more observed with the vermicompost (@0 50 t/ha), and significantly better to other options. Rhizome length was found superior with leaf manure (@0 50 t/ha). Rhizome weight was more with vermicompost (@0.50 t/ha) and was at par with leaf manure (@ 0.50 t/ha). This treatment gave 96.6 and 79.6%, more rhizomes compared to control, respectively. Root length was better with the vermicompost (@0.50 t/ha) and showed parity with the leaf manure (@0 50 t/ha) treated plots. From this finding, it revealed that, use of vermicompost and leaf manure application (@0.50 t/ha) was very effective for higher productivity of Coptis teeta.

Differing from traditional microbial waste treatment, vermicomposting results in the bioconversion of the waste stream into two useful products viz., the earthworm biomass and the vermicompost. The earthworm biomass can be processed into proteins (earthworm meal) or high-grade horticultural compost. Vermicompost is also considered an excellent product as it is homogenous, has desirable aesthetics, very low levels of contaminants and tends to hold more nutrients over a longer period without adversely affecting the environment (Ndegwa and Thompson 2000). A detailed account of vermicomposting technology is available (Nancarrow and Taylor 1998; Rajkhowa et al. 2005).

Eisenia fetida earthworms were obtained from a vermicompost farm in Islamshahr. For breeding and proliferation of the worms, a cylindrical container 50 cm in height and 25 cm in diameter was used. Holes with a diameter of 1 cm were made in the bottom of the container. Semi-rotted cow manure was used for cultivating the worms. Before the preparation of culture medium, cow manure was washed until it discharged a pale-yellow effluent. About 100–200 worm threads were placed in the fertilizer pile. To prevent the entry of light to the substrate, the container was covered with a wet black cloth. The culture medium was sprayed daily with water.
