A pot experiment with twenty-four treatment combinations was setup in the net house. The treatment combination consisted of 4 levels of P: P 0 - 0, P 50 - 237.5 kg ha -1 SSP, P 75 - 355.5 kg ha -1 SSP and P 100 - 475 kg ha -1 SSP, 3 levels of Zn: Zn 50 - 5 Kg ha -1 ZnSO 4 , Zn 75 -7.5 Kg ha -1 ZnSO 4 , Zn 100 - 10 Kg ha -1 ZnSO 4 and 2 levels of AM: I 0 - 0 and I 15 - 15 g per pot. The main objective of the study was to reduce the antagonistic interaction between P and Zn by using AM fungi. The results of combined effects of application of P, Zn and AM revealed that P, Zn addition along with AM fungi improved plant growth parameters, plant nutrient content and total nutrient uptake (both above ground and underground portion) of the plant. The results indicated increase in plant height, root length and total nutrient uptake by increasing the level of P, Zn and Arbuscular Mycorrhizae. Also, Arbuscular Mycorrhizae enhanced plant growth by reducing Phosphorus or Zinc deficiency. Antagonistic effects of P and Zn addition on plant nutrient content and total nutrient uptake were absent due to Original Research Article
