“…Black cumin is generally adapted to disturbed soils and semiarid regions [13]. In these areas, low soil fertility due to insufficient organic matter is the main obstacle limiting high yielding productivity, and consequently N fertilization must be applied for improvement in biomass and seed yield.…”

This study was carried out to determine the efficiency of nitrogen (N) doses (0, 30, 60, and 90 kg N ha −1 ) under supplemental potassium (K) application (50 kg K 2 O ha −1 ) on black cumin in 2011 and 2012. The results showed that increased N levels resulted in increasing seed yield and N and K contents in seed, while oil content decreased. The seed yield and oil yield were peaked at the doses of 60 kg N ha −1 and 50 kg K ha −1 . An increase in N doses caused a reduction in oil content regardless of K supply. Saturated fatty acids and oleic acid were slightly increased by K application, while minor changes in linoleic acid were detected. It was concluded that 60 kg N ha −1 with supplemental K application should be advised for enhancement in seed yield, oil yield, and N and K contents in seeds of black cumin without significant changes in fatty acid composition.

“…However, the significant variations in chemical composition of N. sativa seed essential oil have pre-viously been ascribed to the influence of origin of the plant (29), extraction (36), and agronomic techniques used, e.g., sowing date, irrigation regime, or fertilizer type (8,12,26).…”

Nigella sativa L. seed essential oils obtained by hydrodistillation (HD), dry steam distillation (SD), steam distillation of crude oils obtained by solvent extraction (SE-SD), and supercritical fluid extraction (SFE-SD) were tested for their antibacterial activities, using the broth microdilution method and subsequently analyzed by gas chromatography and gas chromatographymass spectrometry. The results showed that the essential oils tested differed markedly in their chemical compositions and antimicrobial activities. The oils obtained by HD and SD were dominated by p-cymene, whereas the major constituent identified in both volatile fractions obtained by SD of extracted oils was thymoquinone (ranging between 0.36 and 0.38 g/ml, whereas in oils obtained by HD and SD, it constituted only 0.03 and 0.05 g/ml, respectively). Both oils distilled directly from seeds showed lower antimicrobial activity (MICs Ն 256 and 32 g/ml for HD and SD, respectively) than those obtained by SE-SD and SFE-SD (MICs Ն 4 g/ml). All oil samples were significantly more active against gram-positive than against gramnegative bacteria. Thymoquinone exhibited potent growth-inhibiting activity against gram-positive bacteria, with MICs ranging from 8 to 64 g/ml.

“…The advantage of suitable season and time of sowing is irreplaceable with any other agronomic management. The advantage of suitable time of sowing was reported in different farming situations (D'Antuono et al, 2002;Talafih et al, 2007;Malhotra and Vashishtha, 2008;Kadhum, 2009;Majumder et al, 2012;Islam and Akhtar, 2013;Vaseghi et al, 2013).…”
