AbstractA field experiment was carried out in a Moderate rainfall area (Jleokhan) in the Nineveh Governorate during the agricultural season 2018-2019 to study the effect of press wheels (use (+) and non-use (-), row spacing’s (17 cm and 34 cm), and sowing rates (80, 100 and 120 kg. ha-1) in the yield and its components of the wheat crop (Triticum aestivum L) Adana-99 cultivated with Zero Tillage (ZT) planting methods and Conventional Tillage (CT) as a control treatment.The results showed that the planting methods (ZT 17+P) and (ZT 34+P) achieved the highest significant values in the traits of plant height, the weight of 1000 grains, and grain yield. (ZT 17+P) planting method was achieved the highest significant values in the traits of tillers No. m-2, spikes No. m-2, biological yield and straw yield. The (ZT 34+P) planting method recorded the highest significant value in protein ratio trait. The sowing rate (120 kg. ha-1) achieved the highest significant values in the traits of tillers No. m-2, spikes No. m-2, and grain yield. In grain yield trait, the interaction between the planting method (ZT 17+P) with all sowing rates and the planting method (ZT 34+P) with (120 and 100 kg. ha-1) sowing rates achieved the highest significant value in grain yield, while the interaction between CT with (80 kg. ha-1) sowing rate has the lowest significant value in grain yield.
