To find the best treatment of cow manure mixing using the best tillage methods and improving sugarbeet yield and soil bulk density and chemical properties, a randomized complete block design the form of a strip plot was replicated three times. Three rates of manure (0, 20, and 40 t/ha) and five tillage methods were used. The analysis of two years of combined data showed that cyclotiller with the mean of 61093 kg/ha and sweep had the highest yield and effect on soil bulk density. Soil chemical properties like soil organic carbon, soil phosphorus, and soil potassium were also measured for data analysis. The results of two-years analyses of data also showed that the cow manure treatments caused more yield of sugarbeet and improved soil physical properties like reducing soil bulk density and soil compaction. Also, using secondary soil tillage machines of cyclotiller and sweep can improve the mixing of manure with soil and soil physical properties and yield of sugarbeet and sugar percentage. In other words, using a cyclotiller and sweep raised the yield and sugar percentage of sugarbeet and reduced soil compaction.
