A field study was implemented at Fayda location which is MRA, (40 km from Mosul city),bread wheat seeds (Triticum aestivum L.) of certified class-Jehan variety and lentils crop (Lens culinaris Medik.) commercial class Ninevah local variety were sown on 14/11/2019. Using (Ras alromh) zero tillage seeder with 2 meter working width and 30 cm distance between each tine. The experiment design was RCBD with one Main factor but included three sub-factors,1st the Wheat-Lentils intercropping system. (60%W.+ 40%L.) (72 kg.ha-1.W.+32 kg.ha-1. L.), (40%W.+ 60% L.) (48 kg.ha-1. W. + 48 kg.ha-1. L.), (100% W.=120 kg. ha-1), and(100% L=80 kg.ha-1). The 2nd subfactor tow sowing methods liner sowing (30 cm) and cross sowing (30*30 cm), and the 3rd-factor (+)(-) Pallas-45 herbicide using. All the three subfactors were under control of the main single factor. The results indicated that cross sowing either for the individual sowing or intercropping sowing significantly enhanced the plants growth, yield and its components traits, such as, chlorophyll content index, flag leaf, No. of spikes, biological yield, straw yield gm.m-2, grains yield, and protein percentage. Using Pallas-45 herbicide increased grains yield, and some of yield components traits. Protein% trait increased under both levels of cross sowing compared with single sowing 100% wheat crop. Moreover, the intercropping system using cross sowing enhanced yield and its components for both crops , the percentage of yield increasing was more than 30% of the default yield for single sowing of both crops in the same area..(10 Italic)
