Abstract
A factorial trial according to the Randomized Complete Block Design (RCBD) was conducted to study the effects of nitrogen fertilizer levels on Nigella sativa L. during winter season (2003-2004) in the experimental fields of the Field crops Dept . Institute of AL Musaib. The treatments consist of nine levels of nitrogen fertilizer (0, 55 , 110 , 165 , 220 , 275 , 330 , 385 , 440) kg N / ha )N1 ، N2 ، N3 ، N4 ، N5 ،N6 ، N7 ، N8 ، N9). The size of experimental unit was (4x3m) with four rows with (0.75m) a part for each row and the seeding rate used was (8 kg / ha). Analyses of varian and simple correlation were made of the data obtained according to the fallow design (RCBD) with four replications. Less Significant (LSD) was performed for comparison between treatment means. The results show that: Nitrogen fertilizer had significant effects on most characteristics studied, level (440 kg N / ha) (N9) dry weight (2.75 gr plant). However there were non-significant effects of Nitrogen fertilizer on the plant height and number of branches and number box to plant. It is concluded to this research in order to increase growth and yield of seeds of plant Black – Cumin Nitrogen fertilizer level (330 kg N / ha) should be used.
