Abstract：To investigate the effects of biochar and manure on the growth and nutritional quality of silage maize （Zea mays），the experiment was conducted to determine the agronomic traits ofsilage maize at diferent growth stages，yield and nutritional quality by seting up 8 fertilization treatments ofsingle or combined application of bio char，manureand inorganic fertilizer with no fertilization（CK）as thecontrol.Theresultsshowed thatbiocharand manure could promote the growth of silage maize and improved its nutritional quality，and the combined application of biochar and manure was more efective than single application. Compared with no fertilization （CK），single application of biochar （B） increased the fresh and hay forage yield of silage maize by 33.5% and 29.7%（P< 0.05），respectively.Under the condition of no chemical fertilizer，the content of ether extract，relative feeding value，total potassium and zinc in biochar combined with manure （BM） treatment was the highest，and the total phosphorus content of plants was significantly increased，while the neutral detergent fiber was reduced by 20.5% 0 （P<0.05） .Under the condition of applying inorganic fertilizer，compared with the treatment of applying inorganic fertilizer（F）alone，thefresh forageyield，hay forageyieldand zinccontentofbiocharcombined with manure （BMF） treatment were the highest，and the acid detergent fiber decreased by 9.6% 0 ⋅P<0.05） . In summary， biochar combined with manure can significantly improve the production performance of silage maize，and provides theoretical guidance for promoting forage yield increase and farmland improvementin arid and semiarid areas.
