AbstractTo investigate theefectsof manureapplicationonwheat yield，economicbenefits，and soil fertility，an experiment wasconducted using the wheat variety Yannong 19.7 treatments were set up： blank control （T1）， conventional fertilization （T2），optimized conventional fertilization （T3）， 15% replacement of inorganic fertilizer with manure （T4）， 30% replacement of inorganic fertilizer with manure （T5）， 15% replacement of nitrogen fertilizer with manure （T6），and 30% replacement of nitrogen fertilizer with manure （T7）.Wheat yield and soil fertility under each treatment were evaluated.The results showed thatthe manure replacement treatments （T4-T7） increased the numberof effective panicles by 4.6% T 5.3% and the number of grains per panicle by 2.7% 1 4.5% compared to T2. The yield of T4- T7 ranged from9 217.5 to 9442.5kg/hm2 ，with T6 achieving thehighest yield （9 442.5kg/hm²）.The economic benefits of T4-T7ranged from11 993 to 13439 yuan/hm²，representing an increase of 5.5% -18.2% compared to T2，with T4 showing thebesteconomic performance （13 439 yuan/hm2）.In termsof soil fertility，thepHvalues showed litle variationacross treatments.Theaveragesoil organic mater，total nitrogen，alkaline hydrolyzablenitrogen，available phosphorus，andavailablepotassiumcontents inT4-T7treatments were26.2g/kg，1.300g/kg，123.5mg/kg，15.7mg/kg， and 198mg/kg ，respectively，allof which were higher than those in T1，indicating thatpartial replacementof inorganic or nitrogen fertlizer with manure can efectively enhance soil nutrient retention and fertility.This study provides a reference for promoting green and sustainable wheat production.
