Abstract: A study was conducted toassess the long-term effects of balanced and imbalanced use of inorganic fertilizers and FYM on physical soil quality indices after 29thcycle of wheat crop in rice and wheat cropping sequence. The observations were recorded from the continuing long-term fertility experiment initiated in 1984 at Norman. E. Borloug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar. Combined use of inorganic fertilizer along with FYMsignificantly improved the bulk density (BD), water holding capacity (WHC), and hydraulic conductivity (HC) after wheatin both the surface and sub-surfacesoil layer.Lowest bulk density (1.26 and 1.33 g cm-3) in surface and sub-surface soil, respectively was recorded due to N120+P40+K40+FYM and N120+P40+K40+Zn(F)+FYM, whileapplication of N180+P80+K40+Zn(F)+FYM resulted in highest WHC (69.95 and 58.61%), HC (0.278 and 0.198cm hr-1), at surface and sub-soil surface layers, respectively. The positive significant correlations were observed between various soilsphysical quality indices whereasBD and PD were negatively correlated with porosity, WHC and HC. The present investigation clearly points out the significance of balanced use of nutrients including FYM in rice-wheat cropping system for improving the various physical soil quality indices over a long period.
