Interpretive Summary:

Technical Abstract: A double-cropped, irrigated, conservation-tilled, 3-year rotation was initiated in 1996 to determine the fertilization needed to balance nutrition supplied as surface-applied broiler litter and to determine the ability to produce high crop yields in conservation tillage. Cotton, peanut and pearl millet for grain are planted in the summer and wheat and canola are planted in the winter. The plots are arranged in split-plots with broiler litter rates of 0, 4.5, 9 and 13.5 mg ha**1 applied on the surface before each crop as the main plots and fluid fertilizer treatments as the split plots. High rates of broiler litter are rapidly increasing soil test P in the surface soil, signaling potential problems in the future. Litter application provided yield and value ha-1 increases for cotton, grain pearl millet, wheat and canola. Any litter application was detrimental to peanut yield and grade.
