Abstract

In order to study the effect of methanol and weeds interference on yield and some physiological traits of wheat (Triticum aestivum L.), an experiment factorial was conducted based on randomized complete block design with three replications in the research farm of the Faculty of Agriculture and the Natural Resources of University of Mohaghegh Ardebili in 2018. In this experiment, factors were included methanol levels in five levels (control or foliar application with water, foliar application 8, 16, 24 and 32% methanol), and two levels of interference and non-interference of weeds. The results showed that foliar application 32% methanol under no interference weeds condition increased chlorophyll index, relative water content, stomatal conductance (39.95, 47.32 and 75.01% respectively) in comparison with no application of methanol under interference weeds. Also, foliar application 32% methanol under no interference of weeds increased grain yield. Based on the results of this study, it seems that methanol foliar application can be suggested as a proper approach for increasing of yield of wheat under weed interference
