Abstract:
An experiment was conducted to assess the nutrient composition of vermicompost as influenced by different organic substrates viz., rain tree litter and paddy straw spent mushroom compost. This experiment was undertaken at Vermicompost Yard of Division of Soil Science, College of Agriculture, Pune during 2021-22. Different proportion of rain tree litter and paddy straw spent mushroom compost were used for the production of vermicompost by using earthworm species Eisenia fetida. HDPE Vermibeds of size 12 X 4 X 2 feet were used for this study. There were five substrate combinations viz. 25% rain tree litter (RTL) + 75% paddy straw spent mushroom compost (PSSMC), 50% tree litter + 50% paddy straw spent mushroom compost (PSSMC), 75% tree litter + 25% paddy straw spent mushroom compost (PSSMC), 100% rain tree litter, 100% paddy straw spent mushroom compost (PSSMC) made for the preparation of vermicompost and replicated four times in completely randomized block design.
The objective of this experiment is to assess nutrient composition of vermicompost prepared by using different combinations of rain tree litter and paddy straw spent mushroom compost. It can be reveal from the data that pH (1:10), EC (1:10), organic matter, C:N ratio, total nitrogen, phosphorus, potassium, iron, zinc, manganese, copper were significantly influenced by different combinations of rain tree litter and paddy straw spent mushroom compost. The EC of vermicompost was ranged between 1.47 to 2.81 dSm-1. Vermicompost prepared from 100% rain tree litter reported significantly higher EC (2.81 dSm-1) which was closely followed by 50% rain tree litter and 50% paddy straw spent mushroom compost. Lower EC (1.47 dSm-1) was reported with 100% paddy straw spent mushroom compost. The C:N ratio of these vermicompost prepared by using rain tree litter and paddy straw spent mushroom compost was ranged between 9.02 to 14.26. 50% rain tree litter and 50% paddy straw spent mushroom compost was reported significantly lower C:N ratio 8.83% which was closely and statistically at par with 100% rain tree litter (9.02) and 75% rain tree litter and 25% paddy straw spent mushroom compost (11.72). Macronutrients like nitrogen (2.23%), phosphorus (1.13%) and potassium (0.823%) was found significantly higher in vermicompost prepared by using 100% rain tree litter. However micronutrients like iron (1150ppm), manganese (276.5ppm), zinc (276ppm) and copper (73.25ppm) were also found significantly superior than rest of the treatment. It could be concluded from this experiment that rain tree litter from various campuses can be good source of organic matter with nutrients for preparation of vermicompost by using Eisenia fetida species of earthworms.
