Abstract
Humic acid is an organic acid without environmental destructive effects that is applied for increasing germination rate and wheat establishment. In order to evaluate effects of different levels of humic acid on germination of four wheat cultivars; an experiment was conducted in 2008 at Research Laboratory of Faculty of Agriculture, Ferdowsi University of Mashhad. A randomized completely block design with four replications used with factorial combination of humic acid concentration (0, 36, 54, and 72 mg/l) and wheat cultivars (Sayons, Chamran, Pishtaz and Sabalan). Results showed that all traits except germination rate were significantly different (p
