A pot experiment was conducted to evaluate the effect of chelated micronutrient fertilizers(amino acid and EDTA chelated) and inorganic micronutrient fertilizer on growth of rice cultivated in aerobic soil.Results regarding biomass,biological properties,chlorophyll and IAA contents showed non-significant differences between amino acid chelated micronutrient fertilizer(AA-Met) and EDTA chelated micronutrient fertilizers(EDTA-Met),whereas these differences were highly significant when AA-Met and inorganic micronutrient fertilizer treatments were practiced.The protein contents of different type micronutrient fertilizer treatments were significant difference and were in the following order: AA-Met>EDTA-Met>inorganic micronutrient fertilizer.The biomass,chlorophyll and IAA contents of different content of AA-Met showed non-significant differences when AA-Met1 and AA-Met2 were applied whereas these differences were highly significant when AA-Met2 and AA-Met3 were practiced.AA-Met will take the place of EDTA chelated fertilizer and can be widely broadcasted because of its low dosage,low cost and high efficiency.
