Effect of integrated nutrient management on soil physico- chemical properties of date palm orchard under alkaline soil condition

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.
