Özet

Oats (Avena sativa L.) with high grain β-glucan content may be useful for both human nutrition and animal feeding. The objective of this study was to determine the effects of nitrogen and irrigation levels on oat grain β-glucan content. In this study, higher levels of nitrogen increased oat grain β-glucan content in both years. Nitrogen levels at 100 kg ha-1 (N2) gave the greatest β-glucan content. Increased levels of irrigation tended to decrease grain β-glucan content in oats. Cultivar effect on oat grain β-glucan content was significant. Generally, the "804" line had the highest grain β-glucan content in all treatments. Significant and positive correlations between grain β-glucan content and grain yield, protein content, 1000-grain weight and test weight were observed while a negative correlation between β-glucan content and hull percentage was significant in both years. The results of this study indicated that cultivars and increased nitrogen amounts had a major effect on grain β-glucan content, whereas irrigation had no effect on grain β-glucan content in oats.
