This field experiment was conducted at the Agricultural Research Farm of University of Tabriz in 2015 to evaluate the effects of integrated management of dodder on some growth parameters of chickpea (Cicer arietinum L.). The experimental design was a randomized complete block design with three replications. Treatments were trifluralin (2 L.ha-1) + wheat straw mulch, wheat straw mulch + glyphosate application (75 g a.i. ha-1), irrigation after 15 days + naphthalene acetic acid, chlorthal dimethyl application (10 kg.ha-1) + irrigation after 15 days, tillage + wheat straw mulch, wheat straw mulch + irrigation after 15 days, trifluralin and chlorthal dimethyl application. The highest grain yield of chickpea was obtained in chlorthal dimethyl application and wheat straw mulch + glyphosate application (respectively 2764 and 2617 kg.ha-1) that were higher than those of other management treatments. The highest biomass of dodder was observed in wheat straw mulch + irrigation every 15 days. Results indicated that use of wheat straw mulch and irrigation after 15 days were not high enough to prevent the spread of dodder. Generally in treatments that only the non-chemical manageemnts were used the dodder infestation was occured and led to chickpea grain yield loss. Therefore, it seems that integration of cultural control (mulch application) with chemical control could be suitable option for dodder management in the chickpea fields.
