Review on Iron Nutrition and Control of Iron Deficiency in plants

Abstract:
Iron is the first essential microelement for all higher plants which was detected by Griss in1843.It is used for chlorophyll formation as well as the functioning of various iron-containingenzymes in higher plants. Although abundant in most soils,most of these iron is not available fOrplant uptake.So,iron chlorosis is a world wide problem.The recent progress in study on iron nu-trition is reviewed in this paper.The causative factors, diagnostic practices and control measuresof iron deficiency in plants are also summarized.
