A field study was carried out to determine magnesium and iron status in economically important field crops wheat, maize and sugarbeet as well as snap bean and potatoes grown under field conditions using the portable chlorophyll meter. The meter readings showed non-significant correlations with Mg-concentration in wheat leaves while iron concentrations were negatively correlated with the apparatus readings. Both Mg and Fe concentrations in maize leaves were negatively correlated with the meter readings. In contrast, Mg and Fe concentrations in sugarbeet, snap bean and potatoes leaves showed highly significant positive correlations with chlorophyll-meter readings. Thus, it is suggested that the apparatus can be used to predict Mg and Fe status for dicot short-life crops. Because of their accumulation under unbalanced fertilization, the meter, like any other tool, could not express the actual needs for Mg and Fe for monocot cereals. |
