With 7 corn hybrids at various locations in Virginia, hybrids were more important than growing conditions as a source of variation in oil content; the reverse was true for the effect on protein content. With 3 levels of N, P, and K, and at 10,000 and 16,000 plants per acre, the location, planting rate, and N level all significantly affected protein content. Protein content was significantly higher under drought conditions than under good growing conditions. Highest protein yields occurred with the higher plant stand and heaviest N application. None of the factors had any appreciable effect on oil content:
