Abstract
The Fe deficiency reduces quality of grain wheat leading to Fe deficiency in human. Thus this experiment investigated the effects of foliar application of nano-iron oxide (2 and 4 g L -1 ), iron chelate (4 and 8 g L -1 ) and iron sulphate (4 and 8 g L -1 ) on grain yield, yield components and quality, foliar chlorophylls and carotenoids contents, peroxidase (POX), catalase (CAT) and ascorbate peroxidase (APX) activities of bread wheat (Triticum aestivum L.) during 2011 and 2012, in Isfahan, Iran. Regardless of iron sources, Fe application increased all of the traits as compared with the control. Harvest index, 1000- grain weight and chlorophylls contents increased as the rate of iron sulphate and iron chelate increased, but these parameters decreased at the higher rate of nano-iron oxide. Highest 1000-grain weight, harvest index, grain and grain carbohydrate yields were produced by application of 8 g L -1 iron sulphate followed by application of 2 g L -1 of nano-iron oxide, while the greatest chlorophylls, grain protein and iron contents and grain protein and iron yields were obtain by application of 2 g L -1 of nano-iron oxide followed by application of 8 g L -1 iron sulphate. The results suggested that Fe fertilization increased antioxidatnt enzymes activities and chlorophylls contents, yield, yield components and the grain quality of wheat, however, application of 2 g L -1 nano
