Effect of Arbuscular Mycorrhizal Fungi and Different Combination of Foliar Application of Nutrients on Nutrient Uptake and Yield of Aerobic Rice

Background: In Aerobic rice cultivation, crop would faces water and nutrient deficiency; it would be a difficult for roots to reach in those situation. During that stress situation VAM fungi helps to observe water along with essential nutrients results out of efficiently increases the nutrient uptake. Methods: The field experiment was conducted during 2022 at wetland farms, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore. The experiment consisted of thirteen treatments, which includes different recommended doses of VAM 50, 62.5 and 75 kg ha-1 together with different combinations of foliar application of 0.5% of urea, 0.5% of ZnSO4 and 1% of FeSO4. Conclusion: The experiment results concluded that the combined application of 150 % of recommended dose of VAM and foliar application of 0.5% urea + 0.5% of ZnSO4 + 1% of FeSO4 at 25 and 45 DAS, significantly increased the nutrient uptake, by improving the morphology of shoot and root biomass under upland condition.
