Abstract:
This study was carried out to evaluate the seed yield and oil content of black
cumin, at Qlyasan Research Station, Faculty of Agricultural Sciences, Sulaimani
University [35 ̊, 34′′ 307′ N; 45 ̊ 21′ 992′′ E with an altitude of 765 masl ], during
winter season 2008-2009. Factorial experiment including four rates of Nitrogen fertilizer
(0, 20, 40, 60) kg ha-1and GA3 (0, 50, 100) ppm pre –flowering spray, conducted in
Completely Randomized Block Design (CRBD) with 4 replications. The application of
nitrogen in different levels showed significant values in most of the reproductive traits,
the level of 20 kg N ha-1 showed the superiorities as compared to all other levels.
Gibberellic acid spray caused significant increase in all yield characteristics except No.
of capsules plant-1, weight of 1000 seed and biological weight, while oil % was superior
when no GA3 was added. The interaction of 20 kg N ha-1 with 50ppm GA3
predominated in both seed and oil yield.

Key words: Medicinal plant, Black cumin, Phytohormons, Nitrogen application
