Alfalfa productivity is influenced by the nutrients it receives during growth. Research showed that using certain nitrogen fertilizers increased nitrogen content in alfalfa. Phosphorus and potassium levels also affected nutrient content. The best yield was achieved with specific fertilizer rates. Nitrogen levels in alfalfa varied throughout growth stages, with higher doses leading to increased nitrogen content. Optimal fertilizer doses resulted in higher green mass yields. Overall, alfalfa productivity is mostly influenced by mineral nutrition and weather conditions.
