The treatments were conducted according to randomized completely block design (R.C.B.D) with three replications .the results revealed that total number of weed plants were reduced by 93.5% by rising wheat seed rate ( 120 ) kg/ha together with Crew330 herbicide 1000 and 2000 ml/ha and The treatment ( Crew330 herbicide + 180 and 240 kg/ha) controlled the wild barley by (96.2 , 98.1)% respectively also dry weight of Wild barley was reduced to 98.1% by using (2000) ml/ha of herbicide with (180) kg/ha of wheat seeding rate and Wheat growth characters were not affected by experiment treatments except the leaf area which increased significantly by 24.2 % by using 120 kg/ha wheat seeds + 2000 ml/ha spraying rate.

This study was conducted to determined effect of eight genotypes of Uplaned cotton ( Gossypium hirsutum L. ) which were ( Coker 310, Stonovill, Dunn-1047, Cafko-1,Montana , Dise, Ashaur and Lachata) in grouth , yield components and qualitative characters , also for determinated oil percentage and contents of fatty acids . in the seeds . A field experiment was conducted in two locations , first at Horticulture dep. Of Agriculture college / University of Tikrit , second was at shirqat district of salahaldeen government of summer season of 2011 . The study included four quantitative and qualitative characters of oil, using a spilt plot arrangement of Randomized complete Block design of factorial experiment with three replicates the genotypes were in main plots, while two dates of picking were in sub plot, the results were as : and significant differences were shown in two dates of picking excelled the first time for oil,oliec,palmatic (23.50,16.33 and 23.73%) respectively and lienoliec (23.73%)significant differences were shown between dates of picking and locations except oleic percentage excelled the first dates of picking in shirqat in oil, palmatiec percentage (23.60 and 23.74%) respectively and the seconed date of picking in shirqat for lienoliec percentage (54.62%) significant differences were shown in means of the genotypes for all characters excelled Stonovill Montana, Dise, Coker 310,for oil,oliec, lienoliec, palmatic percentage ( 24.74,17.83,56.77 and 24.84 ) respectively. significant differences were shown in the two locations and genotype. The interaction between two dates of picking and the genotypes was significant characters on two dates of picking shown. significant effect was shown between the genotypes , two dates of picking and the locations also for the interaction between them.

Study was carried out at two sites of Nineweh province, location of the city of Mosul of the College of Agriculture and Forestry / University of Mosul, and the location of Hammam Alaleel which located at distance 32 km south of Mosul, during the season 2009 and the aim of a comprehensive assessment of ten varieties of muskmelon local and foreign the evaluation included characteristics of vegetative growth, and yield the quantitative and qualitative characteristics of fruits carried out the experiment design sectors randomized complete R.C.B.D. and three replicates for all characteristics, and make statistical analysis of each site separately and also conducted compilation analysis of the two sites and the all qualities. The results showed that there are significant differences in the studied traits for the ten varieties and characterized cultivar Baste in the majority of adjectives vegetative growth and for both locations while the Excellence cultivar KaroLee to gave highest product of quantitative 66,8 and 44,8 t / ha for the two sites by following, and the analysis of accumulative of the two sites were indicated superiority of cultivar Baste in adjectives plant height, number of branches and number of leaves. while the highest total production for the variety KaroLee gave 56,4 t / ha, followed by cultivar hafith himself gave 48,28 tons / ha means that the results of the analysis the accumulative of two sites and analysis for each site was demonstrating the superiority of cultivars KaroLee and hafith himself to give the highest productivity unit area .
