The Effects of Japonica Rice on Different Nitrogenous Nutrition

In order to define the effects of reducing nitrogenous nutrition on the quality of rice, nineteen Japonica rice varieties were studied. The nineteen varieties were planed on normal and low nitrogenous nutrition. The research showed that reducing nitrogen fertilizer the appearance and milling quality were cut down, but the amylose content and gel consistency was increased. The effects of reducing nitrogenous nutrition on the quality of rice were different among different rice varieties. Reducing nitrogen fertilizer, the milling and cooking quality of Japanese varieties Koshihikari, Toyonishiki and Chinese varieties tie-jing4, Shennong15 were improved, but the chalky color character of Japanese variety Fukunishiki and Chinese variety Liaojing454-17 were obviously decreased, the rice glue was harder, the gel consistency was decreased.
