Abstract
Two field experiments were carried out in the Desert Research Center (D.R.C.), Agricultural Experiment Station at EL-Kharga Oasis, New Valley Governorate (27°47.7 42 N, 30°24.7 63 E) during the two  growing seasons of 2015/ 2016 and 2016/ 2017 to study the effect of sowing dates and rates of nitrogen fertilizer on productivity and quality of quinoa. Results showed that the effect of sowing dates on all studied parameters was significant except, number of inflorescence/ plant, carbohydrates % and oil % don’t affect significantly by sowing dates during the two growing seasons. Sowing date in 1st December had the highest values for all studied traits as compared with the rest dates during the two growing seasons. There were significant increases in values of studied parameters with increasing nitrogen fertilizer rate up to 150 Kg N fed.-1but without significant in number of inflorescence/ plant and saponin % during both seasons. The interaction between different sowing dates and nitrogen fertilizer levels had a significant effect on yield and quality of quinoa except, number of inflorescence/ plant and saponin % which did not any significant by the interaction between sowing dates and nitrogen fertilizer during the two growing seasons. Cultivation of quinoa on 1st December and fertilization by150 kg N fad-1 gave maximum values of studying parameters during the two growing seasons at the desert area under NewValley conditions.
