Abstract EN

This study was conducted in Telafar region, Mosul governorate during agriculture season 2002-2003 to study the effect of three plow types (mold board, chisel and one way disk) with two plowing depths (10-15 cm) (15-20 cm) and two sprinkler irrigation systems (center pivot and solid set) on growing and production properties of corn (plant height, number of ears plant, number of rows/ear, length of ear, ear diameter, number of grain/ear, weight of 100 grain and grain yield). Randomized complete block design (split-split plot design) was used and the results analyzed statistically.

The results showed that the mold board, chisel and one way disk plows with the two plowing depths and with center pivot irrigation system surpassed in plant height and number of ear/plant properties.

The mold board plow with the depth (10-15 cm) and center pivot irrigation system surpassed in number of rows/ear, and the one way disk plow with (15-20 cm) depth and center pivot irrigation system surpassed in grain yield property and its yield was 11.02 ton/ha.
