Abstract
A greenhouse pot experiment was conducted with various levels and combinations of P and Fe being applied to a sandy calcareous soil in which snapbeans were grown as a test crop for growth response and nutrient uptake. Phosphorus, Fe, Ca, Mg, Mn and Zn were determined on the 21 and 35 day old snapbeans and dry matter yield was recorded separately for tops and roots. Symptoms of Fe deficiency developed on plants in those pots where no Fe was applied. With the application of 20 ppm Fe, the symptoms were prevented. Maximum plant growth was obtained when 150 ppm P was added. The mineral content of snap‐bean plants was affected by increased levels of applied P and Fe. Significant interactions were found between P and Fe treatments for most of the characteristics measured. High Fe decreased Zn and Mn in plants and high P decreased them further.
