An ongoing field experiment was conducted at Long-term fertility experiment, Pantnagar, to study the effect of inorganic fertilizer and manure on physical and chemical properties of soil of seven treatments viz. 100% NPK, 100% NPK+Zn, 100% NP+Zn, 100% N+Zn, 100% NPK+FYM, 100% NPK-S+Zn and Control, four replications of each treatment. Farmyard manure is applied at the rate of 15 t/ ha. Soil bulk density, hydraulic conductivity, penetration resistance, pH, electrical conductivity, organic carbon and available macronutrients were determined. In general among all the treatments 100% NPK+FYM showed better result and control gave poorest result.
