Abstract :

Seed coating one of the methods seed amplifier in which various materials attach to the outer surface of the seed to minimize negative environmental impacts and improve plant establishment. This research in order to study the effects of different methods of seed coating on the germination of Triticum aesativum Zagros variety in Different Soil moisture levels and Sowing Depth and was conducted in a growth chamber with farming soil as factorial in a completely randomized design with four replications. Treatment of coating materials include four levels: none coverage (NC), mineral matter (CC), material with organic base (OC) and material with hydrogel base (HC), soil moisture treatment in three levels including 9%, 14% and 21% of dry soil weight, planting depth treatment in both levels of surface cultivation and three times of the diameter of the seed was used. During testing germination percentage was evaluated, the results showed that all main effects of treatments (coating materials, soil moisture and planting depth) on germination of Triticum aesativum Zagros variety at 1% is significant. The interaction between treatments of soil moisture and seed cover, as well as treatments of planting depth  and seed cover, on the germination percentage significanted (p <0.01). The interaction between soil moisture and planting depth treatments as well as the triple effects of sowing depth, soil moisture and seed cover on germination percentage was not significant (p> 0.05).
