Seed source of corn production (hybrid SC704), desirable seed size and the relationship between seed vigor and seed size on the grain yield of field corn conducted at the Agricultural Research center, Safiabad Dezful in 2008 with 3 replicates was evaluated. In this study, seed source (Khoozestan, Moghan and Khorasan) was used as the main factor and seed size (6, 6.5 and 7 mm) as subplot. The design of the field experiment was split plot in logout of randomize complete block. Results indicated an increase in seed size, seed number in cob, row number in cob, seed number in row, and 1000 grain weight with different seed sources. In general, the results showed that grain yield increased with high seed size and vigor. High grain yield was obtained with the seed source of Khoozestan and 7 mm seed size (8717.7 Kg/ha) compared to the seed source of Moghan and Khorasan (8583.7 and 8344.3 Kg/ha) respectively. © 2012 Academic Journals.

In order to determine the best source of maize seed production (Hybrid Single Cross704) and the most suitable seed size and also to determine the relationship between the seed size and foundation and their effect on the mean daily germination, the daily germination speed, Seedling Vigor Index, primary root length and seedling length were performed by three irritations in 2007 crop year in the agricultural survey center of Safi Abad in Dezful in laboratory conditions using the standard germination test. In this study, the factorial test was used in the form of completely randomized design using 100 seeds by 4 replication. The treatments under study included 2 factors of seed source in Khouzestan, Mooghan and Khorasan and the factor of seed size (6, 6.5, 7 mm) was determined using standard germination test. The results showed that in the laboratory conditions, there is a meaningful difference between the characters regarding the resources and different sizes of seeds, so that the mean daily germination was affected by the experimental treatments and they became a considerable percent statistically. The comparison of the means showed that the mean seed germination in Khouzestan with the size (6 mm) by the mean (13.5) germs source had the minimum germination number by the size (6.5 mm) and the mean (10.6) daily germs. The cooperative interaction of the seed size and the seed sources have a considerable difference with each other regarding the daily germination speed. The comparison of means shows that the Khuzestan seed source with (6.5 mm) seed size and the mean (0.093), have the most daily germination speed and the least daily germination speed regarding Khorasan seed source with (6.5) and (7) mm seed size and it was 6mm with the mean (0.073) for Khouzestan. The Seedling Vigor Index also has been affected by the seed source and size, so that it got a considerable difference. This way, the source of the Mooghan seed with (7 mm) seed size and the mean (4271.3) has the maximum Seedling Vigor Index and the source of Khorasan seed with (6 mm) seed size and the mean (3106.2) has the minimum Seedling Vigor Index. The primary root length also was affected by the seed size and source, so that the source of Khorasan seed with the mean (20.4 mm) has the most primary root length and the source of Khorasan seed with the size (6.5 mm) and the mean (15.6 mm) has the least primary root length. The seedling length hadn't any significant difference under the effect of the seed size and source.
