Abstract:
The field experiment was conducted at Agricultural and Horticultural Research Station (AHRS), Bhavikere under UAHS, Shivamogga to study the effect of different levels of fly ash on physical and chemical properties of soil. The four levels of fly ash 10, 20, 30 and 40 t ha^-1 with and without Plant Growth Promoting Rhizobacteria were tried with ten treatments. The effect of fly ash and their combination with and without Plant Growth Promoting Rhizobacteria showed a non-significant effect on bulk density, particle density and EC. A higher dose of fly ash 40 t ha^-1 recorded significantly higher maximum water holding capacity (35.05%), porosity (59.41%), organic carbon (5.54 g kg^-1) and increased the pH of acid soil to near neutral (6.38) over control from 30 to 90 days after planting. Fly ash 40 t dddha^-1 with Plant Growth Promoting Rhizobacteria significantly increased the availability of macro and micro nutrients as compared to control.
