- Abstract
The main objectives of the study were to investigate the effects of nitrogen rate on Fe absorption and distribution of iron-rich rice. Field experiments were conducted in 2010-2011. Two rice cultivars,H9405(iron-rich cultivar)and W1240(check cultivar),were grown at five nitrogen(N)rate. The results showed that Fe contents of plant, peduncle, hull, rice bran and milled rice at maturing stage of iron-rich rice H9405 were significantly higher than those of W1240. Fe absorption from heading to mature stage and Fe distributing to the grain of H9405 were higher than those of W1240. With N rate increasing, Fe content of plant at maturing stage and milled rice increased, and mored Fe moved to panicles, and H9405 showed more sensitivity to N rate than W1240 did. These results showed that Fe content in milled rice was improved with N rate increasing, besides iron-rich rice showed more sensitivity to N rate.
