Abstract

Field research was carried out at Kirkuk Governorate (Altun Kopri district) near the village of Hasar Al- Kabeer for the agricultural season of 2022 to compare two types of GR and Turbo emitter and two levels of water salinity on yield (0.55 EC dSm-1), (4.40 EC dSm-1), with four levels of deficit irrigation (ETc 120%), (100% full irrigation) (75% ETc), and(0.50% Etc). The results were analyzed with a factorial split-split plot design, and the F-test and Duncan's test determined the differences between factories and averages. The system was evaluated at the beginning of the experiment in comparison between GR and turbo emitter performance. Results were shown to outperform the GR emitter on the Turbo emitter in four qualities: coefficient of manufactured variety (% CV), uniformity of emitter flow (% Eu), uniformity field emission F.EU%, and absolute uniformity field emission F.Eua% with results of 0.01% 9.45% %,99.09%and 99.87 % The system was also evaluated in the middle of the experiment in comparison between fresh water and saline water in same qualities parameter. The results were shown by the superiority of fresh water over saline water as the results were (0.0379%), (0.0932%), (98.83%), (97.16%),(98.28),(98.93), and(99.85),(99.87)respectively. The most important results showed the superiority of the GR emitter interference treatment with freshwater at water stress level (100% ETc) in the total yield Mg ha−1 and plant height cm for red cabbage were 26.50 Mg ha−1 and 35.00 cm. Turbo emitter with saline water at 50% water stress given the best value (24.20 leaf plant−1).
