Abstract
A field experiment was conducted in the greenhouse and at the field of the dept. of field crops, college of agriculture, university of Baghdad, For two years, 2010 and 2011. The aim was to study the quolity of cultivars of tobacco, s cigar and cigarette, by affecting of different doses of Du soils contamination, that is without soil contamination (control treatment) 1:1 kilo soil contamination( low dose) and 1:2 kilo soil contamination (high dose). Three varieties of tobacco were used. Two of them are for cigars (Criollo, Habana) and the later is for cigarette (SH). The design of experiment was systematic arrangement of whole plots according to randomized complete block design with three replicates. The results showed there was no significant differences among varieties in total Nitrogen (T-N), protein, Ash, and Chlor percentage, for tow years. Doses of contaminated soil were significant in chemical properties of carbohydrates. High dose gave 13.4%, while, low dose gave 10.4% and control treatment gave 6.8%. Low dose superior on control significantly, while, there was no superior in T N and Protein percentage in first year. In the Second year, high dose gave 3.4% and superiored on control that gave 2.9% and low dose that gave 2.4%, while, high dose gave 10.9% and superiored on control treatment that gave 9.3% and low dose that gave 7.5% in protein percentage. There was no significant defferences among contamination doses in carbohydrates properties. Ash and chlor percentage not affected by doses of contamination rays during two years. The interaction between first variety and third doses of contamination was significant and gave 14.1%, in tha first year. In the second year, there was significant effects in T N. The third variety with third dose gave 3.8%, therefore it was superior on the rest of the treatments. The same treatment was superior in protein percentage in the second year and gave 11.8%. The conclusion of this study was the effect soil contamination rays in chemical features of the plant and range ability in change this characters make cigar and cigarette conclusion in chemical tobacco characters that effected of dose contamination uranium.
