In a three-year field experiment carried out on a sandy soil the effects of overhead irrigation and mineral fertilization on two oat cultivars were studied. It was found that sprinkling increased the grain yield by 24%, while mineral fertilization - by 15%. Combined treatments caused a 47% higher grain yield and a 86% higer straw yield. The cv. ‘Boruta’ gave a higher yield then cv. ‘Rumak’. The productivity of water grew on plots with high doses of fertilizers, the effects of NPK were also greater on irrigated plots. The applied treatments caused significant changes in the plants morphology and anatomy. They manifested themselves in an increased growth length of stem and panicle, number and weight of grain in a panicle, and larger surface of the flag leaf. Anatomical changes were shown in the less of xerophytic features and poorer resistance of the sprinkled plants to lodging.

An increased pigment content was found in flag leaves of highly fertilized oat. The irrigation and fertilization applied modified the activity of nitrate reductase, phosphatase and peroxidase in leaves. High rates of mineral fertilizers increased the content of total nitrogen and nitrates in the grain. Sprinkling decreased the amount of nitrogen in the crop but increased amino-acid content, mainly that of lysine, threonine, leucine and glutamic acid. The Rumak cultivar had by 40% more amino- acids in comparison with the giving higher yields Boruta variety. Digestibility increased in the grain of sprinkled plots, also the essential amino-acid index and limiting amino-acid index increased under the influence of watering which improved the biological value of the crop.
