Uptake of N P K and yield of Kharif sorghum as influenced by soil and foliar application of micronutrients

Grain yield of kharif sorghum was significantly affected due to the application of micro nutrients. Application of RDF + 15 kg ZnSO₄ + 15 kg FeSO₄ ha⁻¹ significantly increased sorghum grain yield to 20.58 q ha⁻¹. Nitrogen content in fodder increased after the addition of recommended dose of fertilizer along with micronutrients, at flowering from (0.23 to 0.52) to (0.23 to 0.65%) at harvest. Phosphorus content also increased at flowering from (0.26 to 0.39) to (0.28 to 0.49) at harvest. Potassium at flowering from (0.50 to 0.78) to (0.61 to 0.82). Application of RDF + 15 kg ZnSO₄ + 15 kg FeSO₄ ha⁻¹ significantly increased N uptake 50.79 kgha⁻¹, P uptake 31.85 kgha⁻¹ and K uptake 32.29 kgha in⁻¹ kharif sorghum.
