The Impact of Slow-Release Nitrogen Fertilizer Combined with Organic Fertilizer on Oat Yield and Quality

With the advancement of sustainable agriculture, improving crop yield and quality while reducing environmental pollution has become a key research focus in agricultural production. The combined application of slow-release nitrogen fertilizer and organic fertilizer, as an innovative fertilization technique, optimizes nitrogen supply and soil environment through their synergistic effects, thereby improving crop yield and quality. This study investigates the effects of combined slow-release nitrogen fertilizer and organic fertilizer on the growth and quality of oats (Avena sativa). The experimental results show that slow-release nitrogen fertilizer promotes the growth rate and yield of oats, while organic fertilizer enhances photosynthetic capacity and stress resistance by providing organic matter and improving soil structure. The combination of both significantly increases oat forage yield, calcium and potassium content in hay, protein content in grains, mineral absorption, and dietary fiber levels, thus enhancing the overall quality of oats. The study indicates that the combined use of slow-release nitrogen fertilizer and organic fertilizer not only improves crop growth efficiency but also enhances soil health, offering high ecological and economic value.
