COMPARISION STUDY ON THE EFFECTS OF VERMICOMPOST PRODUCED FROM PIG MANURE AND CATTLE DUNG.

In this study, vermicompost was produced from pig manure and cattle dung using the worm Eisenia feotida, assessment of the two compost based on their macronutrient content was done and their effects on soil physico-chemical properties was evaluated in field pea (Pisum sativum var. Arkel) at open field condition. The compost was produced by following the standard procedure for production of vermicompost. Partial decomposition of organic composting material was carried out for 7 days before preparation of vermicompost. Assessment indicated that the nutrient content for nitrogen and potassium was found higher in pig manure vermicompost, while phosphorus content was higher on vermicompost produce from cattle dung.Both the compostwere incorporated into the top 15cm of the soil, separate plots were assigned for each compost and same amount of compost (5 t ha-1) was applied. The result showed that field pea yield and other yield attributing factors were found much higher at the plot where pig manure vermicompost was applied. The soil physico-chemical properties like soil pH, bulk density, water holding capacity, electrical conductivity and important macronutrients was affected at higher level by incorporation of pig manure vermicompost as compared to vermicompost produced from cattle dung.
