AbstractThe study was included experiment carried out at the field crops department, College of Agriculturay and Forestry in the agricultural season 2012-2013, the purpose of the 1st experiment was to study the effect of competition between Triticum aesitivum and Hordeum glaucum. Two factors were selected for this purpose: sowing date (early and Late) and four levels of density (8, 16, 24, 32 plant/ m2). The experiment were set out as a "Complete Randomized Design" with three replications. The data analyzed according to design used in all experiment using (SAS) programe. Duncan test was used for all comparison between means treatments. It can be concluded that the most important results were as follow: There was no significant effect between treatment wether they were sowing at early or late sowing dates for all studied parameters except for leaf area in which the valus of tratments sowing at late sowing date were higher with 6.46 as compard with those sowing at early sowing date .The plant height and percentage of protein were increased as the No. of Hordeum glaucum plants increased in which it was fourd has pots contains four plants Hordeum glaucum were higher with 7.92 and 26 for both characters respectively .as compared with control treatment. There was no significant effect for spike height with increasing numbers of Hordeum glaucum plants.The number of grains/spike, weight of 1000 grains pot yield ,leaves area ,dry weight of plant and biological yield were decreased as the number of Hordeum glaucum plants increased to four plants pot as compared with control treatment in which it was observed the amount of increased were is follows (45.45,45.43 ,43.26 ,45.62 ,18 ,10 ,10.44 %) respectively.for the above parameters
