Abstract: Evaluations were conducted in a greenhouse, microplots and in the field to determine the effect of poultry litter on R. reniformis populations, soil microflora, and cotton yields. In the greenhouse, poultry litter was examined in test 1 at rates of 1, 2, 3, 4, 5, and 6 tons per acre and in test 2, two types of poultry litter; house litter and compost litter were evaluated. Microplots and field plots were also amended with poultry litter at rates of 1, 2, 3, 4, 5, and 6 and 1, 3, and 6 tons per acre respectively and compared to aldicarb (5.6 kg/ha). Results obtained from greenhouse evaluations indicate that poultry litter has a negative effect on R. reniformis population development. Numbers of R. reniformis were reduced by 55% and 72% at the lowest and highest poultry litter amendment levels, respectively. The application of house litter reduced R. reniformis eggs per gram of root by 279.5% and compost litter reduced population 107.4% as compared to the inorganic fertilizer equivalents. Bacterial populations were increased by poultry litter by an average of 220%. In microplots, poultry litter applications at increasing rates of 2 to 6 tons per acre were similar to aldicarb in reducing R. reniformis population levels and increased seed cotton yields. The addition of poultry litter to R. reniformis infested field plots significantly improved seed cotton yields over the standard aldicarb and untreated control. These evaluations confirm that poultry litter has the potential to reduce R. reniformis in cotton.
