Abstract:
The present investigation entitled “Effect of fly ash application with vermicompost on soil physical properties in an Entisol” was conducted during Kharif, 2021 at Krishi Vigyan Kendra, Bemetara. The treatments of the experiment comprised of control, 100% RDF(100:80:60), 75% RDF+20t ha^-1 Fly ash, 75% RDF+20t ha^-1 Fly ash+ 2t ha^-1 Vermi-compost, 75% RDF+40t ha^-1 Fly ash, 75% RDF+40t ha^-1 Fly ash+2t ha^-1 Vermi-compost, 75% RDF+60t ha^-1 Fly ash, 75% RDF+60t ha^-1 Fly ash+ 2t ha^-1 Vermi-compost and laid out in Randomized Block Design (RBD) with three replications. The results of the treatment revealed that the soil pH and EC did not show any significant effect. The physical properties such as bulk density, particle density and porosity were not significantly affected on conjoined application of fly ash and vermicompost. A significant change in hydraulic conductivity, infiltration rate, moisture content and soil strength due to application of fly ash over control was observed. The soil strength was significantly reduced at 5 cm depth resulted by the addition of organic matter through vermicompost and fly ash. The increase in hydraulic conductivity due to different treatments of fly ash ranged from 55.32 cm/day to 76.84 cm/day as compared to control 55.32 cm/day and RDF 60.39 cm/day, respectively. The increase in infiltration rate due to different treatments of fly ash ranged from 0.84 cm/hr to 1.58 cm/hr as compared to control 0.84 cm/hr and RDF 1.02 cm/hr respectively. The increase in moisture content at harvest due to different treatments of fly ash ranged from 20% to 25.24% as compared to control 20% and RDF 22.10% respectively.
