This study was carried out in Agricultural Research and Experiment Station at University of Kirkuk within (Saiada) area، South of Kirkuk for 2015-2016 growing season. Aclay - loam soil texture was used to the research. Three different factors were undertaken: Agricultural systems (Zero-Tillage، Conventional Tillage and Locally Tillage)، with two levels of forward speeds (3.61 and 5.82) km / h and seed rate (104 and 140) kg/ ha. The results showed that the superiority of zero-tillage system to achieve the best values for each of seed emergence rate، number of grains per spike، 1000-Grain weight and grain yield with (87.31%، 33.16، 30.78 g and 1764.25 kg / ha) respectively. While conventional tillage system achieved best values for each of slippage percentage، practical productivity and draft power were recorded (8.251%، 1.035 ha/ h and 5.898 kw) respectively. Speed factor was impact on some properties in which first speed with (3.61) km/ h was significantly flounced (slippage percentage، draft power, seed emergence rate and 1000-Grain weight) which illustrated (8.039%, 4.342 kW, 84.87% and 30.35 g) respectively. However، second speed (5.82) km/ h showed best values for practical productivity (1.071) ha/ h، number of grains per spike (32.11) and grain yield (1519.94) kg/ ha. For seed rate، the best result showed the number of grains per spike and 1000-Grain weight (32.27 and 30.68 g) was achieved in (104) kg/ ha while the (140) kg / ha seed rate indicated the best value for slippage percentage، practical productivity, draft power, seed emergence rate and grain yield (9.128% ,0.877 ha/ h , 6.266 kw , 84.51% and 1543.88 kg/ ha ) respectively. The result of the interactions between three factors showed the superiority of zero-tillage system to achieve the highest net profit, especially when speed was (5.82) km/ h with a (140) kg/ ha seed rate was recorded a value of (972958.3) ID/ ha.
