C rop and fertilizer management practices can increase wheat grain protein without sacrificing yield. Growing wheat with high grain protein begins with selecting the appropriate variety and providing enough fertilizer to meet the wheat’s requirements for growth and grain yield. If nutrient levels are sufficient to meet yield goals, then providing adequate available nitrogen (N) may be the most ...
