Abstract

To evaluate the effectiveness of trifluralin tolerance in different varieties of wheat, barley and oats crops, greenhouse and field experiments were conducted in the College of Agriculture and Natural Resources, Razi University, Kermanshah, Iran, in 2015 and 2016. In greenhouse study, 64, 12, and 38 varieties of wheat, barley and oats were tested, respectively. In the field study, 11 oat varieties (Ugf775456, Wallaroo, Ozark and ...), two barley (Nosrat and Ryhan) and two wheat (Psrsi and Pishtaz) varieties were examined. In both studies, 2.5 liters of trifluralin per hectare (commercial form) was used. A factorial experiment in a randomized complete block design and a randomized complete block design with three replications were used in greenhouse and field experiments, respectively. In the greenhouse study, germination percentage and dry weight and in the field study, grain yield, emergence percentage and length of coleoptiles were recorded. The use of herbicide increased seed yield and germination percentage of oat crop higher than barley and wheat. Coleoptiles length of crops and wild oat was significantly different. The difference of coleoptile length of wheat, barley and oat crop allow the use of trifluralin as layers.
