Abstract:

The research was carried out during the two agricultural seasons 2020-2021 in Al-Hasakah Governorate, the village of Qana, which is located 25 km south of Hasakah, according to the design of complete random sectors with three replications, with the aim of studying the effect of the cultivation method on the formal and productive characteristics of the onion crop. Three varieties were used in the research. F1 hybrid of onions (Hercules, Montana, Early White). The study showed the superiority of the onion variety Hercules in most of the morphological characteristics, and the largest plant length was recorded after 60 days of germination, reaching 24.43 cm, the largest stem thickness was 0.66 cm, and the largest diameter of the dry head reached 5.7 cm. The Early White variety exceeded the plant height of the final harvest, recording 68.67 cm, and the dry head length and diameter (8.41 – 5.7) cm. The Hercules variety showed a significant superiority in most of the early and qualitative traits, as it recorded the lowest number of days for final maturity, which reached 184 days compared to the rest of the varieties, and the largest number of leaves on the plant reached (4) leaves, and the scaly leaves coated for the dry head reached (3.7) leaves, It also scored the lowest percentage of double bulbs, which was (0.333)%.Montana cultivar recorded the highest percentage of dry matter compared with the rest of the studied varieties, reaching (20.31)%.The two cultivars Earley White and Hercules were significantly superior in most of the productive traits, as they outperformed the dry head weight and achieved (131.1 – 130.1) g, respectively, and the productivity of one line of heads reached (39.34 – 39.02) kg respectively, and in the yield of the experimental piece, where It recorded (157.3 – 152.3) kg, respectively, and the highest productivity per unit area was (6556 – 6346) kg / min, respectively.
Key words: Hercules, Montana, Early White, quality, primacy
