Grain yield enhancement of wheat is of particular importance due to its high level of cultivation and
consumption in Iran. Seed treatment with Humic acid (HA) as an organic acid derived from humus
has been reported as an effective way in improving wheat grain yield. In order to study the effect of
seed treatments with two HA substances on grain yield, yield components, morpho-physiological
traits, germination rate, root length and shoot length of five bread wheat genotypes, over three
cropping seasons, a factorial experiments based on completely randomized design in lab and
randomized complete block design in farm with three replications were conducted at Sararood
Agricultural Research station. The HA treatments were included seed treatments with Humex,
Humica and control, and the second factor was genotypes including Rijaw, Owhadi, Karim, Azar-2
and Buma-2. Results of simple analysis of variance showed that the effect of seed treatment on all
measured traits such as germination rate, germination percentage, root length, shoot length, root dry
weight and shoot dry weight were significant (P< 1%). The results of combined analysis showed that
the simple effect of seed treatment was significant for many traits including grain yield, number of
grains per spike, 1000-grain weight, peduncle length, plant height, canopy temperature and leaf
temperature, indicating the effect of seed treatment on these traits are grain yield. The highest grain
yield was obtained at Humax treatment and the lowest value at control treatment.
