Application Impact of Coal Fly Ash, and Water Hyacinth on Cultivation of Tomato

Abstract

Few pot and field experiments were conducted to study the effect of levels of coal fly ash (CFA) which is a byproduct of Kota Super Thermal Power Station, on physicochemical properties of soil and the yield parameters of Tomato. The objective of the experiment was to study a reaction between the constituents of soil. & CFA to upgrade the quality of soil making it suitable for cultivation of Tomato. Physicochemical studies have been carried out for different composts obtained by successive replacement of CFA for soil/earth in constituents of original and reference composts. Water Hyacinth(Species of Eichornea of family pontederacdia) were used as organic manure. Physiochemical analysis was conducted after the harvest of Tomato. Increase in rate of growth and improvement in quality of produce was observed with the increase in percentage of CFA in the range studied.  This study of graded level of CFA amended soils revealed an increase in the content of N. P. K. Ca, Mg, S, Fe, Mn, Zn and Cu.
