Abstract
Abstract The experiment was carried out in one of the farmers in Al-Najmi District, Al-Rumitha of Al-Muthanna province, during the winter season of the year 2010 . The experiment was used the implement this experiment design R.C.B.D with three replicates to influence the appointment of agriculture (20/10, 10/11, 30/11) in some characteristics of growth, yield and quality for three genotypes from the plant Nigella sativa L. (Iraqi, Syrian and Jordanian) . The experimental results showed that The Iraqi genotypes exceeded in all vegetation growth traits (plant height, number of branch, number of leaves) and in all merits of yield traits including the seed yield.plant-1, total seed yield. There was no statistical difference between the Iraqi genotype and the Jordanian genotype and the latter exceeded in the weight of 1000 seeds as well as the percentage of the fixed oil and its production . Although The first plant date was associated with the highest number of leaves. While the second planting date was associated with the highest plant height, the third planting date was remarkable with the number of branches and seed yield. The components of yield was exceeded in the seeds yield.plant-1. The first was exceed in the production of fixed oil . When studying the interaction between the genotypes and the planting date, the first planting date for the Iraqi genotype exceed in all vegetative growth traits studied. In yield traits, The interaction was exceed in the merits of the seeds yield.plant-1 and the total seed yield. Although this combination exceed in the production of fixed oil .
