Influence of Corn (Zea mays L.) Cultivar Development on Grain Nutrient Concentration
While corn productivity has been increased by the adoption of high-yield hybrids, there are concerns that increased grain potential may be associated with diminished grain nutrient concentration. Ten corn (Zea mays L.) cultivars representing five technological levels (landrace variety, commercial va...
