Abstract

The present study aims to characterize and determine the potential use of trash fish manures in agricultural fields. Nutrient and minerals were analyzed in trash fish samples. High amount of nitrogen (6%), phosphorous (5%) and potassium (4%) were present in trash fish and used for plant growth study. Three commercial plants viz. Lycoperscon esculantum, Hibiscus esculenta and Solanum melongena were selected for analysis. The shoot length, root length, total length, number of leaves, leaf length, biomass of the plant and roots division were measured in every 15 days interval upto 45 days. After 45 days, the percentage of root length growth of L. esculantum , H. esculenta and S. melongena in experimental plants showed 84, 99 & 82% and the shoot length growth were 50, 45 & 66% higher than the control plants.  The outcome of the result in the experimental plants showed fast growth than the control plants. Two way Analysis of Variance showed that the root length and shoot length significantly affect the plant growth.
