Abstract
In the present experiment, fly ash application to soil generally improved soil pH condition. The improvement of soil pH was greater with bituminous fly ash than with anthracite fly ash. Treatment of fly ash also made available phosphate content increased. But phosphate content in cultivated tomato plants was in inverse proportion to content in soil due to high pH of experimental soil as well as hot and dry weather. Amount of phosphate in plants had a strong positive effect on the yield of tomato. Number and weight of harvested fruits was greatest from July 21 to July 30, the time considered as peak harvesting period of second fruit truss. In conclusion, the application of fly ash improved physico-chemical properties of experimental soil.
