- The use of poultry litter and sewage sludge as a nutrient source continues to increase. The purpose of this study was to evaluate the use of these organic by-products as a source of nutrients for peanut (Arachis hypogaea L.) production. From 1995 to 1998 poultry litter was applied on 13 on-farm sites and composted municipal sludge was used in three of these on-farm experiments. Fertilizer was also applied in all experiments. Rates of poultry litter ranged from 1.9 to 7.2 Mg ha21. Composted sewage sludge rate was 2.0, 4.0, and 8.1 Mg ha21. Commercial fertilizer was mixed and applied mixed together at 180, 40, and 111 kg ha21 for nitrogen (N), P2O5 and K2O, respectively. Phosphorus (P) and potassium (K) were also supplied separately at a rate of 40 and 111 kg ha21, respectively. Seven of 13 sites had increased yield as a result of poultry litter. Fertilizer increased yield in only two experiments. Sludge increased yield in only one experiment and only the highest rate. At one site, poultry litter gave a greater yield than fertilizer when both increased yield above the control. Treatments did not inﬂuence total sound mature kernels percentage (TSMK).
