Foliar application of Fe and-or Zn increased dry weight production of the areal parts significantly. Differences in leaf area index existed among Zn treatments while Fe treatments had no effect. Mean leaf area ratio decreased significantly with the increase in Fe and-or Zn levels. Increasing Fe and-or Zn rates increased mean crop growth rate and mean net assimilation rate significantly. Both Fe and Zn had a significant effect on yield. In general, yield raised steadily with increasing Fe and-or Zn application to a point, above which differences were not significant. Yield response to Fe and-or Zn treatments was mainly due to differences in number of pods produced per square meter, number of seeds per pod, and seed weight
