Abstract

In In order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (RCBD) with 4 replications in Saat-Loui agricultural station of West Azerbaijan province. In this research, the first factor (A) contained two levels 20 and 40 cm inter rows, the second factor (B) contained three levels 2, 4 and 6 cm intra rows and the third factor (C) contained three different varieties of Baft, Bukan, and Arbil. The specimens were planted on April 22nd, 2009. The results showed that the effects of plant density and harvest arrangement on grain yield, oil yield and oil percentage were significant. The highest and least grain yield, oil yield and oil percentage obtained from varieties of Baft and Arbil respectively. Oil percentage of inter rows 20 cm and intra rows 6 cm was 31.26 and 33.77 percent respectively. The content of oil percentage in variety Baft was 32.33 percent. Overall, the best content of oil percentage obtained from inters rows 20 cm with intra rows 6 cm in variety Baft about 37.47 percent.
