Forage maize yield and quality data in the NW of Spain (Galicia and Asturias)

Maize Cultivar characterization in the NW of Spain in Tabular data form., for 23 years in seven locations and corresponding to three different cultivars named 200,300,400. Production and quality variables: Dry Matter yield (kg MS/ha), Crude Protein yield (kg PB/ha) and Net energy for lactation yield (UFL/ha). Cultivar names first letter is "G" for Galicia locations and "A" for Asturias sites.
