Physico-Chemical Characterization of Fly Ash and Its Effect on the Growth of Soyabean Plant (Glycine Max.)

Abstract

The physico-chemical characterization of fly ash, three different soils and irrigation water was carried out. The growth of soyabean plants was studied in 0%, 2%, 5%, 10%, 15%, 20%, 25% fly ash blended soils. Growth of plants was monitored regularly after every month up to three months from the date of sowing for all the three blended soils in rainy season of the year 20010.Based on the data obtained it is found that 5% -10% fly ash-soil blending concentrations improved the physical properties of soil and also contributed to better growth and yield of soyabean plants in rainy season. The present work shows the utilization of fly ash in agriculture may provide a feasible alternative for its safe disposal without serious deleterious effects and may save the cost of fertilizers and elevates the economy of farmers if used in proper ratio by blending.
