The study looked at how different fertilizers affect the yield of winter triticale in Serbia. They used nitrogen, phosphorus, and potassium at different levels to see which combination gave the best results. They found that using a mix of all three fertilizers led to the highest grain yield. The quality and yield of triticale varied between years and treatments. In 2015, the highest yield was achieved with a specific combination of fertilizers. The researchers also found a correlation between grain yield and grain weight, with different results in different years. Overall, optimizing fertilizer use is crucial for successful triticale production in certain environments.
