Abstract: A study was conducted to assess the long term effects of fertilizers and FYM on physical properties and crop productivity after 19<superscript>th</superscript> cycle of sorghum-wheat cropping sequence in a Vertisol. The combined use of inorganic fertilizers (100 % NPK) along with FYM @ 10 t ha<superscript>-1</superscript> significantly improved the bulk density, hydraulic conductivity, available water capacity, water stable aggregates and coefficient of linear extensibility of soil and yield of crops. Total productivity (sorghum + wheat) was found to be positively correlated with these properties. [ABSTRACT FROM AUTHOR]
