| Abstract A field study was Carried Out through Fall season of 2013, at Kirkuk Govermonate , AL - Hawija region , in silty texture soil , to evaluate the feed disc in new seed direl (Nardi) introduced Iraq recently, and which is used in planting several crops including maize. The research included three factors, the first factor (Large diameters of 12 mm , small of 7 mm and seeds mixed seeds of (50% large and 50% small), the second three diameters of feeding holes tablets were standard 4.5 mm, concave 4.5 - 10 mm and trans formed with 6 mm and the third includes three ground speed for planting operation included 2.7 , 3.7 and 5.1 km / h. Using randomized complete block design in split split plot armament with three replicates where seed sizes seed distribution in line percent and yield of ears, loss percent and filed emergence percent, grains yield of maize The interaction between the three factors revealed that three were several good combination in their effect on studied traits. Each of large and mixed seeds with tablet holes of 6mm for second speed, Mixed seeds with concave holes for third speed and small seeds with tablet holes 6mm for first speed were surpassed other combinations in line and loss percents. The mixed and small seeds with concave tablet holes for first speed were surpassed depth uniformity of seeding, while the small seeds with concave holes for field emergence percent. The higher yield of maize (ears and grains) found from combination of large seeds with concave tablet holes for second speed. | ||
