Abstract
This experimental was carried out in a clay loam soil at the experimental research station of the field crop department, College of Agriculture, University of Tikrit during the autumn season 2004. This work is aimed to study the effects of three plow types (disc, chisel , mold board) and three nitrogen fertilizer levels(0,240,480) kg Ha on growth and grain yield characteristics of Maize (Zea mays L.) variety IPA 3001. Seed quantity used in experiment was 7.5 kgha.
