To evaluate the effect of on-farm seed priming and methods of zinc sulfate application on seed emergence properties, yield and yield components of two corn cultivars, an experiment was conducted as factorial in randomized complete block design with three replications during 2012 at research farm of Bu-Ali Sina university, Hamedan. First factor was methods of zinc sulfate application containing four levels of no-application, broadcasting in soil, banding and foliar application. Second factor included on farm primed and no primed seeds and third factor consisted of two corn hybrids (Es-sensor and Biaris). Analysis of variance showed that percentage and rate of emergence of on farm primed seeds increased about 16 and 12% respectively also emergence uniformity coefficient in primed seed while banding zinc sulfate comparing with no-primed seed and broadcasting zinc sulfate showed 74% increase. In Biaris cultivar priming increased significantly the number of kernel per ear. In two cultivars the highest 100 seeds weight was achieved of primed seed plus banding or foliar zinc sulfate application. In this study the highest grain yield was obtained of primed Biaris seed cultivar combined with zinc sulfate banding application ( 1370.42 g/m2) that was higher about 9.6% comparing with no-primed and no zinc sulfate treatment.

To investigate the effect of on-farm seed priming and arbuscular mycorrhizal fungi in different amounts of phosphate fertilizer on emergence, yield and yield components of a semi-mid maturity corn hybrid (ES-SENSOR), an experiment was conducted at the research station of Agriculture College, Bu-Ali Sina University in 2012 in a factorial randomized complete block design with three replications, where the first factor was priming in two levels including control (non-primed) and priming with water and second factor was arbuscular mycorrhizal fungi (control and application of mycorrhizae) and the third factor was phosphate fertilizer application in three levels (non-use, 50 and 100 percent of recommended phosphate fertilizer). Results showed that seed priming increased seedling emergence rate by 15 percents. The highest symbiosis percentage was about 65.47 which was obtained by application of mycorrhizae and 50 percent of phosphate fertilizer recommendation. Also seed priming increased the number of grains per ear. 100 seed weight was also increased significantly by priming and inoculation with mycorrhizae at 50 percent phosphate fertilizer recommendation. In this study, seed priming increased grain yield by 22.32 percent. The highest yield rate of 1249.59 g/m2 was obtained in 50 percent phosphate application and use of mycorrhizal symbiosis. Therefore by application of mycorrhizal fungi in the direction of sustainable agriculture, phosphate fertilizer can be reduced by up to 50%.
