The experiment was conducted to evaluate the efficiency performance of the combine implement which manufactured and assembled locally and studying it’s effect on some soil physical properties and total costs in one of the Agricultural College University of Baghdad Experimental Fields in loamy soil, 2017. Brazilian Massy Ferguson Tractor (MF-650) was used with the combine implement as a machinery unit. Three machinery unit speeds included 3.15, 4.60 and 6.10 km/h and seedling treatments included manufactured combine implement, seedling and fertilizer implement and manual seedling were used in this experiment. Soil bulk density, soil moisture content, amount of added water and total costs were measured. Nested design under randomized complete block design with three replications was used in this experiment. Least significant differences (LSD = 0.05) level under 0.05 probability was used to compare treatment means. The results can be summarized as following: 1. Incrased machinery unit speeds from 3.15 to 4.60 km.h-1 led to significant increase in soil bulk density from 1.30 to 1.36 Mg.mˉ³and significant increase in soil moisture content from 0.18 to 0.20 %. 2. Manufactured combine implement treatment was superior in getting less soil bulk density stood 1.22 Mg.mˉ³ higher soil moisture content stood 0.22%.and less amount of added water during the season stood 1103.43 mm. and less costs stood 796370 Iraqi Dinars. 3. The interaction between 3.15 km.h-1machinery speed and manufactured combine implement got less soil bulk density stood 1.19 Mg.mˉ³, while the interference between 6.1 km.h-1 machinery unit speed and manufactured equipment was superior in obtaining a higher moisture content stood 0.229%. 4. Using the locally manufacturing modified combine implement for primary and secondary tillage, shallow furrow opener, seedling and fertilization in one time was successfully done in this study with high performance efficiency.
