| Abstract | ||
| The experiment involved spraying varying concentrations of amino acids (0, 2.5 and 5 cm3L-1) with varying levels of nitrogen fertilizer (200, 250 and 300 Kg N ha-1) and observing the effects on wheat growth and yield, both qualitatively and quantitatively, as well as the nutritional status of it. Nitrogen fertilization and amino acid supplementation increase plant height and yield of wheat plants. A synergistic interaction exists between nitrogen and amino acids, promoting optimal plant growth and productivity. Spraying amino acids with low nitrogen rates, especially the second rate, can achieve crop values close to the recommended nitrogen rate, reducing nitrogen fertilizer usage by about 16.7%. The effect of nitrogen fertilization was most pronounced at the highest rate (300 kg N ha-1), where carbohydrate and protein content reached its maximum. The effect of amino acids was most pronounced at the highest concentrations (5 cm3L-1), where carbohydrate and protein content reached its maximum. The effect of amino acids and nitrogen fertilization was more evident on the nitrogen content of leaves, while the phosphorus and potassium content in leaves were not affected. It can be said that spraying amino acids at a concentration of 5 cm3 L-1 gives growth, yield and nutritional status to wheat plants with low levels of nitrogen fertilizer, especially 250 kg N ha-1. Therefore, spraying amino acids can reduce the amount of nitrogen fertilizer with the intention of harming the growth and yield of wheat, thus reducing the cost of production and increasing profitability | ||
