By correct management of agricultural implement application can perform seeding operation faster and more precisely. In order to study the effects of tillage methods and soil evenness, planter types, and their speeds on maize seeding precision, an experiment was performed. It was carried out in a split-plot in basis of a randomized complete block design with 3 replications. Main plots were tillage methods and soil evenness including: moldboard plow + two-pass disk plow + leveler (T1), moldboard plow + two pass disk plow (T2), and moldboard plow + one pass disk plow (T3). Subplots were planter types including: pneumatic planter (P1) and mechanical planter (P2). Sub-sub plots were included of planter speeds including: 4 km.h-1 (S1), 5.5 km.h-1 (S2) and 7 km.h-1 (S3). Measured parameters was consist of means of seeding distance and their standard deviation, skip index, quality feed index, multiple index, and seeding C.V. (coefficient of variance). The results of analysis of variance showed that tillage methods and soil evenness the same as planter type treatments have no significant effects on total parameters however planter speed treatments and their interaction with planter type treatments have a significant effect on all measured parameters. Comparison of means showed that the best planter speed was 5.5 km.h- 1 . At higher speed (7 km.h-1 ), mean of seeding distance, standard deviation of seeds and skip index increased, and quality feed index, multiple index and seeding C.V. decreased significantly. In view point of quality feed index, P1 treatment had more sensitive than P2 and it is necessary to its engaging with soil will increased to this index is increased.
