AbstractA field study was carried out to grow the maize Yellow crop For the autumn season 2019-2020 in one of the agricultural lands in Al-Nimrud district in Nineveh Governorate, Moreover, field soil textures were loamy silty clay. The randomised complete block design (RCBD) was used to analyse the results under a split-split plots system with three replications. The investigation included the effect of three factors, the first one is seed depth (3 and 5) cm, and the second factor is the planter speed, which were (2.5, 4.8 and 6) km/h. The last factor is the spring tensile strength at three levels, that were (242, 217, and 198) N , The indicators studied were adopted for each of slippage ratio (%) , fuel consumption (l/ha), draft force (kN), loss ratio (%), achieved seeding depth (cm), ). Furthermore, total seed yield (ton/ha), . The most important results obtained were as follows:- As the depth (5) cm was significantly superior in all attributes The study also showed that the first speed (2.5) km / hour exceeded significantly in the highest values of each fuel consumption (3.99). L / ha: Seed depth achieved (3.84) cm and total yield (10.76) t / ha. While the pulsating tension force level (242) Newton achieved the best moral values in all characteristics except for the percentage of loss (5%). Whereas, the bilateral interaction of depth (5) cm with speed (2.5) km / h recorded the highest significant values in the characteristic of each fuel consumption (5.17) l / ha, realized seed depth (4.80) cm and total seed yield (11.09) t / ha. As for the bilateral depth depth (5) cm with the spring tensile strength level (242) Newton achieved significant superiority in all traits except the characteristic of the percentage of loss. As for the velocity interference (4.8) km / h with the levels (242 and 217) Newton for the spring tensile strength The highest significant values in attribute depth achieved (3.92 and 3.77) cm, respectively. Whereas, the triple combination of depth (5) cm with speed (4.8) km / h with the second level recorded the highest and best moral value in the attribute depth of the achieved seeds (4.93) cm from the rest of the characteristics.
