    Naked oat ( Avena nuda L.) is an important grain, feed and forage crop. Here the experiment was carried out in a non-weighing lysimeter with four irrigation quotas (750m 3· ha -1 , 1500m 3· ha -1 , 2250m 3· ha -1 and 3000 m 3· ha -1 ) and fertilizer versus non-fertilizer to analyze the effect of different water and fertilizer conditions on the yield and quality of naked oats. The experimental results showed that fertilization can effectively increase the yield of naked oats by about 40%. At the same time, fertilization significantly increased the protein content of naked oats by 0.83%, increased fat content by 0.34%, crude fiber content by 0.75%, and starch content by 2.94%. As irrigation quota increased, the seed yield showed a trend of first increasing and then decreasing slightly, and was highest under the irrigation quota of 2250 m 3· ha -1 (3250 kg·ha -1 ). Meanwhile, increasing irrigation can also increase the protein content (1.17%), crude fiber content (0.26%), and starch content (1.85%) of naked oats. This experiment provides a theoretical basis for the cultivation of naked oats in agriculture-pastoral zone in semi-arid areas.
