Assessing the Efficiency of Different Nitrogen Fertilization Levels on Sorghum Yield and Quality Characteristics

Sorghum is a Poaceae family plant that produces lot of hay. A field experiment was carried out at the University Thessaly’s experimental farm to investigate hay yield and quality characteristics six different sorghum varieties (V1: Buffalo grain, V2: Elite, V3: Big Kahuna, V4: 25K1009, V5: 4264, V6: 5D61) under nitrogen fertilization levels (N1: 0, N2: 80, N3: 160, N4: 240 kg ha−1, using urinary ammonia 40-0-0). Pea for silage production established in same prior cultivation. Hay found differ significantly between tested also influenced by fertilizer. Nitrogen has statistically significant effect on production, with higher supply contributing protein content yield. Other indicators, such as ash, NDF, ADF, demonstrated differences fertilizer levels. According study, variety had stable output “Elite”, which good attributes could be used an alternative feed before development.
