Abstract
This study was conducted at the field of the College of Agriculture Dohuk University during the seasons of 2006-2007 and 2007-2008. Four varieties of barley were used in this study (local black, IPA 99, triticale and Malta 1105). The treatments were arranged in factorial experiment (4x3) using randomized complete block design with four replications. One cut and two cut were preformed for the midlines of each treatment. The data were recorded on ten randomly selected plants. The results showed superiority of non cut treatment. The interaction between the cut and non cut the IPA 99 was superior to the rest of the varieties, where it was less affected by the cut than the rest of the varieties, followed by Malta 1105. As for the green fodder, the two cut treatment was superior to the one cut treatment. The cut was led to increasing the number of tillers. IPA 99 was the most tolerant variety to the cut as compared with the other varieties followed by Malta 1105 for both season. As for the straw yield , the local black was superior in the two cut treatment, whereas IPA 99 was superior in both (non cut and one cut treatments) . It can be concluded that IPA 99 can take one cut and could be used to produce cereals yield.
