Results from two years of university research trials show a foliar application of Nitamin 30L Steady Delivery nitrogen applied with a foliar fungicide increases yields an average of 10 bushels per acre (bu/A). Georgia-Pacific Plant Nutrition, manufacturer of Nitamin brand fertilizers, reports the results were compiled from 22 comparison studies at three Midwestern universities in the 2008 and 2009 crop seasons.
The studies were conducted by researchers at the University of Missouri, Iowa State University and Southern Illinois University. The highest gains from the studies came from University of Missouri, where the fertilizer alone produced yield increases of 15 to 28 bushels per acre (bu/A) when applied at tassel (VT stage). When Nitamin 30L fertilizer was applied at one gallon per acre (gal/A) with Headline fungicide, researchers recorded yield boosts of 23 bu/A in 2008 and 27 bu/A in 2009, compared to untreated checks.
