Abstract
The experiment was conducted at the Research Station of Middle Heights, during 2014 and 2015 seasons. Three varieties of Quinoa were used i.e. Ames 13762, NSL 106398 and Ames 137, which were introduced from International Center for Bio Saline Agriculture (ICBA), and they were selected out of five varieties that were grown as observation lines in 2013, to get one variety, high forage and grain yields, also suitable for the local conditions. RCBD design with four replications was used. The traits that were studied were: Earliness, plant height, flowering at 50%, green forage, grain and dry matter yields. Results indicated that there were highly significant (p≤0.01) differences between seasons and varieties in respect to plant height, green forage, dry matter and grain yields. While, no significant effect for the interaction between varieties and seasons overall growth performances. Results indicated that seasons have significant effects on the green forage, grain and dry matter yields at p≤0.01 and p≤0.05. Ames 137 variety produced significantly higher green forage yield (58.88 t/ha) compared with NSL 106398 (37.13 t/ha) and Ames 13762 (50.38 t/ha) and has superiority in dry matter yield (23.75 t/ha) on same varieties, which recorded 15.13 and 19.50 t/ha respectively, and followed by NSL 106398. Results also showed high significant effect of the seasons on plant height, green forage, grain and dry matter yields. Season 2014 was the best, which recorded (151 cm), (52.33 t/ha), (1.6t/ha) and (20.83 t/ha) respectively, compared with 2015 season. Ames 137 variety has gained the highest degrees for animal receptiveness and farmer’s evaluation. The study recommended to use Ames 13762 for grain production, and Ames 137 for forage production.
