EFFECT OF HUMIC ACID DOSE ON BARLEY NUTRITIONAL QUALITY

Abstract

Barley is one of the most cultivated field crops in the world after wheat, corn and rice. It is an important plant used in animal feeding. Barley production areas have also been affected by the decreasing agricultural areas in recent years. The most traditional solution to reach maximum yield and quality values from a unit area is plant nutrition with chemical or organic fertilizers. The use of organic fertilizers is becoming widespread due to the environmental threat posed by chemical fertilizers. In this regard, organic fertilizers containing humic acid, which are known to have positive effects on plant yield and quality, attract attention. The research was carried out in the 2022-2023 barley production season in order to determine the effective doses of humic acid fertilizers on barley nutrition value. In the trial established according to the split-split block trial design, 3 different varieties and 5 different humic acid doses were applied with 3 replications. While the application of 200 ml per decare was found to be important in terms of protein and oil content, no significant effect was determined on the starch, fiber, hardness, moisture, fatty acid values of the application doses.
