Iron chlorosis in chickpea (Cicer arietinum L.) grown on high pH calcareous vertisolN PSaxenaauthorA RSheldrakeauthorGenotypic differences exist in the sensitivity of cultivars of chickpea to iron deficiency. Sensitive cultivars exhibited typical iron deficiency symptoms when grown on calcareous soils with high pH. FeSO4 sprays (0.5%) corrected deficiency symptoms and increased yields by up to 50% in cultivars inefficient in iron utilization, but gave no increase in cultivars that were efficientChickpeaPlant PathologyFertilizer Applications1980ElsevierArticle
