Crops and Soils
Farmers continue to search for ways to increase corn yields, including the use of plant growth regulators. Plant growth regulators, such as gibberellic acid, are organic compounds that modify plant growth processes at very low concentrations. Gibberellic acids control cell elongation and division in plant shoots. Plant growth regulators are more commonly used on fruit and vegetable crops than on grain crops. RyzUp® contains a gibberellic acid and is labeled for corn. The purpose of these trials was to investigate the effect of foliar applications of the plant growth regulator RyzUp® on corn grain yield.
