Abstract
Snap beans (Phaseolus vulgaris L. cv. Bush Blue Lake 283) were grown in 2 greenhouse experiments in soil with 8 fertilizer treatments with a basic NP treatment to which various sources of K and Mg were added. The NP treatment substantially increased vine weight and leaf concentrations and total plant content of N, P, Ca, Mg, Mn and Na. In NPK treatments, regardless of K source, substantial increases in the leaf K and decreases in leaf P and particularly Mg concentrations were shown while only potassium chloride enhanced Mn leaf concentrations. In NPMg treatments, regardless of Mg source, leaf Mg increased but no reduction in K concentration occurred. Adding both K and Mg to the NP treatment did not affect the Mg leaf concentration. Treatments caused a redistribution of elements in plant parts.
