Role of Fermented Organic Manure and Mycorrhiza on Physio Chemical Properties of Soil of Prayagraj, India

The integrated use of fermented organic manure and mycorrhiza has been employed to enhance crop productivity and maintain soil health and fertility. The research titled “Role of fermented organic manure and mycorrhiza on physio-chemical properties of soil” was conducted during the Zaid season of 2023 at the Central Research Farm, Department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology, and Sciences, Prayagraj, Uttar Pradesh, India. The plot was designed in 3X3 RBD having 3 levels of fermented organic manure @ 0, 50, 100 %, Mycorrhiza @ 0, 50, 100 % and N, P, K at RDF respectively. The Variety selected was PDM- 139 released by SVRC, Uttar Pradesh in the year 1974. The average yield recorded was 6-9 q ha-1. Results indicated non-significant with the highest values observed in the control treatment in case of bulk density (Mg m-3) and particle density (Mg m-3) of soil was recorded maximum in T1 (Absolute control) and minimum was recorded at T9 (NPK@RDF + M2@ 10Kg ha-1 50% + F2@ 50 l ha-1 100%). The maximum Pore space (%) and Water holding capacity (%) of soil was recorded at T9 (NPK@RDF + M2@ 10Kg ha- 1 50% + F2@ 50 l ha-1 100%) and the minimum was found in T1 (control). The slight decrease of pH and EC was observed on application of the treatments, the maximum pH of soil was recorded at T9 (NPK@RDF + M2@ 10Kg ha-1 50% + F2@ 50 l ha-1 100%) and the minimum in T1 (Absolute control. The maximum organic carbon (%) and increase of N, P, K of soil was recorded at T9 (NPK@RDF + M2@ 10Kg ha-1 50% + F2@ 50 l ha-1 100%) and the minimum was found in T1 (Absolute control).
