Relative merits of iron determination in corn leaves by colorimetric and atomic absorption spectroscopy for prediction of iron deficiency

, : Relative merits of iron determination in corn leaves by colorimetric and atomic absorption spectroscopy for prediction of iron deficiency. Madras Agricultural Journal 71(4): 266-268

Fe content of maize leaves determined colorimetrically after extraction of chopped samples with o-phenanthrolene corresponded much more closely to visual estimates of no, moderate or severe Fe deficiency than when measured by acid digestion followed by AAS.
