Nitrogen rate influences on protein concentration, yield, and NDVI in spring wheat following pea and cover crop mixture

Tabular data including average wheat grain yield, wheat grain protein concentration, NDVI readings, nugget:sill ratio, nitrogen rate treatment assignments at two scales (subplot and whole plot) are included. Data are associated with Nitrogen rate influences on protein concentration, yield, and NDVI in spring wheat following pea and cover crop mixture, published in Agrosystems, Geosciences & Environment in 2025.
