Abstract

In order to determine the best WEED CONTROL method in spring SAFFLOWER under DRYLAND conditions and to optimize GRAIN YIELD and to materialize the best use of soil and water resourses under DRYLANDs, this experiment was conducted in two cropping seasons (2000, 2001) using randomized conplet block design with 3 replications at Maragheh, DRYLAND Agriculture Research Station. The treatments were: A1= No WEED CONTROL, A2= Two hand weedings (in mid-rosette, and before stem elongation), A3= Mechanical control with sweep cheisd before stem elongation, A4= Chemical control by TRIFLURALIN (Ec=44.5%) with 1.5 L/ha as before PLanting herbicide and A5= Chemical control by TRIFLURALIN with 2.5 Lit/ha as pre PLanting herbicide. Combined analysisg of variance results showed that the year effect was significant at 5% probability level on height of primary secondary branches as well as the number of capitols/plant. Control methods effect was significant at 1% probability level on weeds number per unit area, PLant height and GRAIN YIELD. Only GRAIN YIELD was affected by year ´ control method interactions. Twice hand weeding with 1251 kg/ha GRAIN YIELD produced the highest and was followed by chemical control with 2.5 L/ha TRIFLURALIN with 1002 kg/ha GRAIN YIELD. In conclusion chemical WEED CONTROL with 2.5 L/ha TRIFLURALIN as before PLanting herbicide could be recommended for Maragheh region and other regions with similar climatic conditions.
