A newly bred rice cultivar with high anthocyanin content,Gangteyou 37,was used to study the effects of nitrogen (N) and potassium (K) application patterns on the yield and the nutrition quality of dehulled rice under the total application of N 159 kg/hm2,P2O5 67.5 kg /hm2 and K2O 67.5 kg/hm2 in the field.Results showed that the highest grain yield was obtained when all K was applied as basal fertilizer,60% of N used as basal fertilizer,10% of N applied at tillering stage and 30% of N at spikelet developing stage.Appropriate fertilizer application increased the effective panicles per area,therefore,increased the yield.The fertilizer application patterns rarely affected the contents of amylose,amylopectin and anthocyanin,but proper amount of N applied at the spikelet developing stage increased the content of soluble sugar in dehulled rice.The content of crude fat in dehulled rice was increased by supplying K at the later developmental stage under the same N application pattern.Gama-aminobutyric acid (GABA) tended to increase when N was applied at the spikelet developing stage under the same K application pattern.When all K was applied as basal fertilizer,the content of free amino acid increased first and then decreased with the increase of N application rate at the spikelet developing stage.When 60% of K was used as basal fertilizer and 40% as spikelet developing fertilizer,the content of free amino acid in dehulled rice increased with the increase of N application rate at the spikelet developing stage.Applying N significantly increased the content of crude protein in dehulled rice,but its changes were inconstant under different K application patterns.It is indicated that all K applied as basal fertilizer,60% of N used as basal fertilizer,10% of N applied at tillering stage and 30% of N at spikelet developing stage is suitable to improve rice yield and nutritional quality,and can be used as appropriate fertilizer application pattern for Gangteyou 37.
