The experiment was carried out in autumn agricultural season (2008) and spring (2009) in Hawi Al-Kanesa , Mosul city . Two factors were used in this experiment , seeding rate (24,36 kg/h) and repeated of cutting (1,2,34,5,6) . The experiment was laid out as a Randomize Complete Block design with three replicates .No sifnificant effects were obtaind between seeding rates on dry weight of dodder , number of narrow weed and on its dry weights, hight of plant and number of branches in autumn season , where the weight of narrow and broad leaf weeds in the second rate seeding were surpass in the fist rate. The dry weight of Alfalfa surpass in second rate in comparison with the first in two seasons about 0.57 and 0.77g . At the 2nd seeding rate the dry weight of forage yield were significantly higher at the two seasons .The seeding rates did not show any significant differences in all parameters studied . The dry weight decreased at increasing cutting in autumn , the number of narrow and board leaf , dry weight were decreasing when increasing cuttings , the branch of plant was increased with increasing the cuttings in the two seasons . Dry yield increased at secont cutting in autumn season but in spring season the increase was found at the its cutting .
