Evaluation of different herbicides application on weed controlling and grain yield of rainfed chickpea varieties under no tillage system

This research was conducted in three places in Kermanshah province in 2017-18 cropping season in order to study effect of different herbicides on weeds in chickpea varieties. Experiment layout was strip split plot based on RCBD with two replications. Horizontal factor was included weed control treatments (1. Pendimethalin 4 lit.ha-1 Pre-Planting, 2. Pursuit 0.5 lit.ha-1PP, 3. Sencor 1 lit.ha-1 PP, 4. flumetsulam 20 gr.ha-1 PP, 5. Merlin flex 0.2 lit.ha-1 PP, 6. Merlin flex 0.2 lit.ha-1 Pre-Emergence, 7. Oxyflurofen 0.2 lit.ha-1, 8. Pendimethalin 2 lit.ha-1 PP , 9. No control, and 10. Hand weeding) and vertical factor was included chickpea varieties (1. Azad, 2. Ozbek1, 3. Ozbek6, 4. Akso, 5. Azkan, 6. Adel and 7. Mansour) in Sarpol site, and (1.Iraqi, 2. Ozbek6, 3. Azkan, 4. Ana, 5. Saral, 6. Adel, and 7.Mansour) varieties in Sonqor. Results of ANOVA for grain yield showed significant effect of weed control and variety in Sonqor and Sarpol zahab. In Sonqor grin yield of hand weeding was the highest and merlinflex , pendimethalin and persuit were in next class and higher than no control check. Ana and Adel varieties had the highest yield. In Sarpol zahab, highest yield produced by hand weeding, pendimethalin and merlinflex, respectively. In term of varieties Adel had highest grain yield and Akso and Mansour were located in second class. In Sarab nilofar because of sever hailstone in May 2018 the experiment destroyed.
