Fertility TrialsFertility trials included transplant water treatments, nitrogen sources, nitrogen rates and Poultry Litter. Drought overshadowed many of the trials in 2002. Transplant water treatments did not significantly improve yield in Lincoln Co. While N-source trials in Casey and at the Mike Huff farm in Jackson Co. were similar to previous years, at some locations applying all of the N prior to planting was sufficient due to drought conditions. In Casey Co. yield reach an optimum at 882 lb/a of Ammonium Nitrate. In Meade and Pulaski yields were significantly affected by drought and increasing N rate or sidedressing produced no benefit. The addition of chicken litter improved yield in one location, had little effect in one and reduced yield in a third. Chlorine content is a concern in chicken litter.
