CREA-GB field data 2025-26, N levels

Agronomic data for barley genotypes (old and modern cultivars and mutants) tested under diffrent nitrogen levels at the experimental station of CREA-GB in Fiorenzuola d'Arda, in the 2025-26 growing season.The pale green mutant hus1 (BC2F5 seed bulk from the M24 harvest) and the cultivars RGT Planet, Dasio and Onice, which were selected for their high straw protein content, were sown in replicated plots (6 m2, 350 seeds/m2, two replicates) under two different nitrogen levels: top dressing with 30U N + 16U S (low input) and top dressing with 60U N + 32U S (standard conditions). Sowing date: 5-11-2025. Harvesting date: 22-6-2026.
