Summary of significant effects of cultural practices on seed protein concentration. (A) Soybean seed protein concentration by late-season input treatment (Control, Inoculant application at R3, and N fertilizer applications after R5) at each location and year. Data averaged across rotation types and cultivars. (B) Seed protein concentration by rotation type (CC, cover crop; or fallow) at each location. Data averaged across years, late-season input treatments, and cultivars. Different letters above each bar indicate significantly different means within a year and location at P < 0.05.
