The experiment was carried out in one of the farmers’ fields of Kirkuk irrigation project for the year 2021-2022 in order to study the performance of two types of tillage systems (tillage and non-tillage). Three levels of speed gear shifter were used, which were randomly distributed over the main sectors (5-5.5, 6-6.5, 7-7.5) km/h. The crop used in farming was Triticum durum wheat. The results showed a clear superiority of the factor (non-tillage) over (tillage) in all the studied properties, which were the density of spikes / m2, number of grains / spike, weight of 1000 grains (g), grain yield (kg/hectare), slide rate %, and the actual field productivity of the machine (acres/hour). ). As for the tillage system, it reached (322.55 m2, 49.78, 43.73 g, 3579.26 kg/ha and 6.71 acres/hour) respectively, except for the sliding rate, which was higher in the tillage system by (2.48%)%. As for the speed gear shifter, the speed gear of seeding was affected by all the studied properties, which reached (379.29) m2, (53.50), (44.47) g, (4462.8) kg/acres, (1.15)% and (6.98) acres/hour. As for the interactions between the system with tillage, non-tillage, and tillage with the speed gears used in the sowing process, they were superior in all the studied properties by (447.96) m2, (65.15), (55.56) g, (4700.1) kg/hectare, (0.53)% and (9.43) acres\hour.

This experimental study was carried out in one of the farmers’ fields affiliated to Kirkuk governorate to study the impact of the plowing systems and the type of plows, i.e., the chisel, disc and moldboard plows, and three types of plowing techniques, i.e., once, twice orthogonal, and 3 times on some soil characteristics and the productivity of yellow maize (class 106) at autumn season (2020-2021). The results showed that chisel plow significantly outperformed the other plow systems in the bulk density of the soil, the weighted mean diameter (the length of the ear, the number of rows in the ear, and the grain yield which amounted 1.29, 0.82, 18.06, 16.76 and 6907, respectively. Furthermore, the results showed that there were no significant differences between the variables. Plowing for two times has significant impact on the characteristics of bulk density, weighted diameter rate, ear length, number of rows per ear and grain yield which amounted to 1.36 g/cm³, 0.83 mm, 17.73 cm, 16.4 and 7371.33 kg/hectares, respectively. Nevertheless, the system of plows do not have any significant impact on the moisture content. Besides, the interaction between the chisel plow and the twice tillage has impact on the bulk density, the weighted diameter rate, the length of the ear, the number of rows per ear. The grain yield amounted to 1.36 g/cm³, 0.98 mm, 19.7 cm, 19.7 cm and 7522 kg/hectares, respectively.
