Impact of railway line coal dust of NTPC, Sipat on soil physical properties and yield of rice crop

Abstract

The experiment was conducted on the Mari go round railway line of NTPC, Sipat, Bilaspur (C.G.) with the object to study the effect of coal dust on soil physical properties and yield of rice crop 2018-19. The experiment was laid out in a factorial randomized block design with three factor and three replications with total one hundred forty four soil sample. The soil physical properties includes bulk density which was higher at nearby site (10 m) of the studied area while particle density and porosity percentage were higher at closer site (10 m site) of the area. The particle density of the analyzed soil sample was higher at 10 m site and lower at control site. Porosity percentage was inversely related with the bulk density. Soils of the nearby site (10 m) of the studied area were sandy clay to silty clay loam. The factor A and factor B of the studied area showed non-significant result in case of all three properties i.e., bulk density, particle density and porosity percentage. The yield of rice crop and their straw were low at nearby site (10 m) of the studied area.
