Yield enhancement and biofortification of chickpea (Cicer arietinum L.) grain with iron and zinc through foliar application of ferrous sulfate and urea

This study investigated effects of iron (Fe) and nitrogen (N) foliar application on Fe and zinc (Zn) content in chickpea grain, grain yield, and protein content. Application of FeSO4 at 0.5% at flowering + pod formation stages resulted in the highest Fe (73.50 and 75.34 mg Fe kg−1 grain in first and second year) and Zn (35.08 and 34.21 mg Zn kg−1 grain) content in grain followed by the application of FeSO4 at 0.5% at flowering stage alone (68.27...
