Abstract:
A field experiment was conducted at Agricultural College Farm, Bapatla during 2020-2021 and 2021-2022 to study the direct and residual effect of integrated use of organics and inorganics on soil physical and physico-chemical properties under rice-sorghum cropping system on clay loam soil. The experiment was laid out in a Randomized block design during kharif and split plot design in rabi season and replicated thrice. The organic manures along with inorganic fertilizers were applied to main plots and the three levels of inorganic fertilizers were applied to sub plot treatments for growing rice crop during kharif season and sorghum crop during rabi season respectively. The results revealed that applications of different treatments did not show any marked difference in physical (bulk density, water holding capacity, porosity, Aggregate stability) and physico-chemical properties of soil (pH, EC) at harvest stage of rice and sorghum during both the years of study.
