 ABSTRACT

The experiment was conducted during rabi season of 2013-14.The Soil of experimental area falls under Inceptisols order.  The design applied for statistical analysis was carried out with 32 Randomized Block Design having three factors with the three levels of NPK was 0, 50 and 100 % and Zinc Sulphate was 0, 50 and 100% each. Doses for three levels of NPK as L0 (0 kg N ha-1+ 0 kg P ha-1 + 0 kg K ha-1), L1 (40 kg N ha-1+ 30 kg P ha-1 + 20 kg K ha-1 ) and L2 (80 kg N ha-1+ 60 kg P ha-1 + 40 kg K ha-1) and Zinc Sulphate as Z0 (0.0 kg ha-1), Z1 (25 kg ha-1) and Z2 (50 kg ha-1) The treatment T8- L2Z2 [@100% NPK+ 100% ZnSo4] was found to be the best in all parameters. Data were recorded of post-harvest soil in the treatment T8 as Bulk Density (g cm-3), Particle Density (g cm-3), Pore Space (%), pH, EC(dSm-1), OC (%), available Nitrogen(kg ha-1), available Phosphorous(kg ha-1), available Potassium (kg ha-1), available Zinc (ppm) and available Sulphur (ppm) which were as 1.22, 2.49, 50.99, 7.03, 0.24, 0.72, 308.07, 26.90, 206.53, 0.90 and 13.06 respectively. Soil physical properties such as Particle Density and Pore Space were found non-significant but effect of increasing levels of NPK on Bulk density found significant. Soil chemical properties such as Organic Carbon (%), available Phosphorous and available Potash were found non-significant, but effect of different levels of NPK and Zinc Sulphate on Zinc was significant. Effect of increasing levels of available NPK and Zinc Sulphate on available Nitrogen and available Sulphur were significant but combination of NPK and Zinc Sulphate was found to be non-significant.  Adequate plant nutrient supplyhold the key for improving the sustaining soil  fertility.

Key word: Soil properties, Nitrogen, Phosphorus, Potassium, Zinc, Sulphur.
