| Abstract | ||||
| A field experiment was conducted during the two successive seasons of 2018/2019 and 2019/2020 at the experimental farm of Horticultural Research Station at Sides, Beni-Suef Governorate to improve the growth, productivity and seed oil yield of black cumin plants to foliar application with α-tochopherol (vitamin E), amino acids (Aminoactal) and moringa leaf extract (MLE). Obtained results revealed that the best vegetative growth criteria (Plant height, stem diameter, number of main branches and plant weight at harvest), yield parameters (number of capsules per plant, and seeds yield per plant and per fed.), oil determinations characters (volatile and fixed oil percentages and oil yield /plant and /fed.) and chemical properties such as photosynthetic pigments,herb percentages of N, P and K, free fatty acid contents, iodine and saponification values were obtained due to foliar sprayof the high dose of moringa extract at 5 ml/ l then amino acids 2ml/ l and α-tochopherol (vitamin E) at 100 ppm and with no significant differences being detected between such three concentration of the stimulants treatments. There for, it could be recommended that spraying Nigella sativa L. plantswith the high concentration of moringa leaf extract (5 ml/ l) to enhance growth, seeds yield / plant and /feddan and fixed oil components under the same environmental conditions. | ||||
