Abstract: The effect of organic and inorganic sources of NPK and foliar spray of micronutrient on soil physico chemical parameters was studied. Experimental findings revealed that treatment T₁₆ significantly increased organic carbon, Available N, P₂O₅ and K₂O and reduced soil pH and EC. The application of organic manures like FYM alone or in combination with inorganic chemical fertilizer have also been reported to decrease the bulk density, improved soil porosity and increases water holding capacity of the soil. Therefore, it is advocated that application of 100 kg FYM + 1.50 kg N + 1.00 kg P₂O₅ + 1.50 kg K₂O + 0.00% FeSO₄ + 0.00% ZnSO₄ (T₁₆) build up maximum soil fertility for higher and sustainable production of date palm in Bikaner condiation.
