Abstract: An experiment was conducted during 2016-17 and 2017-18 to assess the performance of sweet orange cv. Blood Red to foliar application of micronutrients. The study comprised of thirteen treatments viz., ZnSO₄ 0.25%, ZnSO₄ 0.50%, ZnSO₄ 1.00%, FeSO₄ 1.5%, FeSO₄ 2.0%, FeSO₄ 2.5%, MnSO₄ 0.25%, MnSO₄ 0.50%, MnSO₄ 1.00%, H₃BO₃ 0.1%, H₃BO₃ 0.2%, H₃BO₃ 0.3% and Control (No micronutrients). The plants were sprayed with micronutrients on first week of april and first week of july. All the micronutrients treated plants produced higher magnitude of growth and fruit yield over control. However, foliar application of ZnSO₄ 1.00% produced significantly higher number of fruits (256.99), fruit weight (195.55g), yield (50.25 kg/plant) and increased the plant height by (9.62%) and spread EW (10.78%) and NS (10.32%).
