A pot experiment was conducted to study the effect of phosphorus and sulphur nutrients as sole and in combination from organic and integration of organic and inorganic sources on groundnut quality. Two studies were conducted to select best phosphorus and sulphur sources by using farmyard manure, poultry manure (PM), vermicompost and sewage sludge. There were six treatments in study one and two, including inorganic source of single super phosphate (SSP) and no phosphorus (control) in trial one and no sulphur (control) in trial two. They were replicated four times in a completely randomized design. Among them the selected best source poultry manure was combined with chemical fertilizer (CF) single super phosphate to supply phosphorus and sulphur by having six treatments (Control, 100%PM, 75%PM + 25%CF, 50%PM + 50%CF, 25%PM + 75% CF, 100% CF) and were replicated three times in a completely randomized design. The oil and protein content of kernels were increased as a result of phosphorus and sulphur. Poultry manure as a sole source of phosphorus and sulphur exhibited the highest oil and protein content. 25% poultry manure with 75% chemical fertilizer as a combination exhibited the highest oil content (45.20%) and 75% poultry manure with 25% chemical fertilizer as a combination resulted in the highest protein content (12.50%) of kernels.
