In order to achieve optimal plant growth and production, essential nutrients must be readily available in adequate quantities and in a balanced proportion to give a good yield, especially broccoli which has health benefits that may not be found in many other plants. For this purpose, this experiment was carried out during the seasons 2019/2020 in the botanical garden of the Department of Biology, College of Science for Women, University of Baghdad, to study the effects of nitrogen and sulphur and their interaction on eight parameters reflecting the overall traits of vegetative growth, yield, and chlorophyll content of broccoli Brassica oleracea L. (var. italic JASSMINE F1 Hybrid). A factorial design with three replicates was used, each with 7 plants treated via foliar spraying. The first factor included three groups; control N0 (distill water spray), N1 (500 mg.l-1 nitrogen), and N2 (1000 mg.l-1 nitrogen). The second factor also included three groups; control S0 (distill water spray), S1 (500 mg.l-1 sulfur), and S2 (1000 mg.l-1 sulfur). We used Urea (CO(NH2)2) as a nitrogen source and zinc sulphate (ZnSO4) as a sulfur source. As for the treatment with nitrogen, the results revealed that N2 treatment caused the significantly highest values in all the studied traits, except for the plant height, where there was no significant difference between N1 and N2. As related to the treatment with sulphur, the results showed that S2 treatment resulted in the significantly highest values of leave area, leave dry weight, and root fresh weight. S2 also caused the highest values, but with no significant differences, of plant height, stem diameter and chlorophyll content index. S1 treatment, on the other hand, caused insignificantly higher values of leave number per plant and main curd weight. Based on the results of the interaction between nitrogen and sulfur, S1N2 treatment resulted in the significantly highest values as compared to all other treatments of all the studied traits, except for the plant height, root fresh weight, and main curd weight. The results presented here may facilitate improvements of Broccoli cultivation with suitable nutrient concentrations for sustainable agriculture. In conclusion, the present study comes up with the following: nitrogen and sulfur and their interaction enhance significantly the growth and production of broccoli.

The Bi2Se3 compound was synthesis by fusing initial compounds consisting of
extra pure elements in stoichiometric ratio from elements compound, charged inside
quartz ampoule. The crystal growth of Bi2Se3 carried out using Brighaman technique
process from melting f (Bi+Se ) at temperature of 810 ºC for about 48 hrs. Single crystal
of Bi2Se3 has been grown in direction (211) after slow cooling on account of heat
gradient to zone furnaces at cooling rate (1-3) C/hr. The structure study of the compound
was determined by x-ray diffraction technique, which it has bismuthinite structure and
orthorhombic unit cell with lattice parameters of a=10.2678 Å, b=11.2392 Å and
c=5.1737 Å
The aim of this research is to measure and analyze the gap between the actual reality and the requirements of the environmental management system in the middle refineries company/refinery cycle according to ISO14001: 2015, as well as to measure the availability of a clean production strategy and test the relationship and impact between the availability of the requirements of the standard and a clean production strategy for the actual reality in the company.
The research problem was determined by the extent to which the requirements of the environmental management system are applied according to ISO14001: 2015 in the middle refineries company? To what extent are the required clean production strategies ava

Show MoreThe optimum conditions for production of fibrinolytic protease from an edible mushroom Pleurotus ostreatus grown on the solid medium , Sus medium, composed of Sus wastes (produced from extracted medicinal plant Glycyrrhiza glabra) were determined. Addition of 5% of Soya bean seeds meal in Sus medium recorded a maximum fibrinolytic protease activity resulting in 7.7 units / ml. The optimum moisture content of Sus medium supplemented with 5% Soya bean seeds meal was 60% resulting in 7.2 units / ml.Pleurotus ostreatus produced a maximum fibrinolytic protease activity when the spawn rate,pH of medium and incubation temperature were 2,6 and 30°C, respectively. The maximum fibrinolytic protease activity was 7.6 units / ml when incubat

Show MoreThe main role of infill drilling is either adding incremental reserves to the already existing one by intersecting newly undrained (virgin) regions or accelerating the production from currently depleted areas. Accelerating reserves from increasing drainage in tight formations can be beneficial considering the time value of money and the cost of additional wells. However, the maximum benefit can be realized when infill wells produce mostly incremental recoveries (recoveries from virgin formations). Therefore, the prediction of incremental and accelerated recovery is crucial in field development planning as it helps in the optimization of infill wells with the assurance of long-term economic sustainabi
