Grain quality affected by N application and plant density could directly influence malting quality. Grain protein content was negatively correlated to steeping degree and steeping rate, and positively related to saccharogenic power. The relationship of grain protein content to a -Amino-nitrogen content and kolbach index could be expressed with a quadratic curve equation, respectively. The greatest decomposition rate of protein might be achieved when grain protein content was 11-12%.
