Improved agronomic practices must be taken in consideration for increasing yield per unit area. Hence, row orientation such as east-west and north-south along with traditional broadcast method were compared to find out best methods not for only reduction of weeds but also for increase in yield of wheat. The study was carried out in RCB design replicated three times at research garden in The University of Agriculture, Amir Muhammad Khan Campus Mardan during Rabi 2014-15. The findings of the study indicated that best results were obtained in term of lower weed density, its fresh and dry weight for either E-W row direction or broadcast compared to N-S rows direction. On the other hand, yield of wheat crop was reduced under traditional broadcast method compared to either E-W or N-S orientation however the yield was higher when the crop row were in east-west direction than north- south row direction. From the results obtained, it is conclude that the crop sowing in E-W orientation had not only reduced weeds and its biomass but also improved yield and yield components of wheat as compared to N-S row orientation and broadcast. The cultivation of wheat in east west orientation is viable option for not only environment friendly but also for the reduction of cost of production.
