Abstract
The field experiment was carried out in the winter season (2021-2022) and(2022 - 2023) at the University of Tikrit – Faculty of Agriculture – Field Crops Department Research Statio,which is characterized by its gypsum soil, studying the effect of spraying with glycine and lysine acid and the element of iron and the overlap between them in some growth and yield characteristics and the active substance of Nigella sativa L. The experiment was designed according to the design of the complete randomized sectors (RCBD) with a working experiment (with three repetitions and each repetition 18 transactions, as it included combinations of glycine and lysine with iron, and analyzed the data of the two seasons collectively to find out the effect of amino acids, iron, coefficients and seasons and their overlaps except for the active compounds. It was analyzed for the first season and for only one repetition. The results of the statistical analysis of the data showed that there were significant differences in all the characteristics studied. The treatment of amino acids glycine exceeded 100 mg.L-1 + lysine100 mg.L-1 in each of the vegetative growth qualities represented by the height of the plant with an average of The number of branches of the plant as well as the qualities of the crop and its components represented by the number of Capsules in the plant and the number of seeds in the Capsules and the weight of 1000 seeds and the total seed yield, the treatment of iron spraying with 100 mg L -1 morally exceeded in each of the vegetative growth qualities represented by the height of the plant and the number of branches of the plant with an average of as well as the qualities of the crop and its components represented by the number of Capsules in the plant and the number of seeds in the Capsulesand the weight of 1000 seeds and the total seed yield. As for the seasons, the second season has morally exceeded the number of Capsules in the plant and the number of seeds in the Capsules and the weight of 1000seed seedsand the total seed yield
