Effect of poultry manure as partial substitute for P and S on the yield and quality of groundnut

A Potculture experiment was conducted to evaluate the yield and quality of groundnut with poultry manure as partial substitute for P and S. Poultry manure (PM) was integrated with chemical fertilizers (CF), SSP and elemental S at different ratios. There were six treatments replicated three times in a completely randomized design (T1-Control, T2- 100%PM, T3-75% PM + 25% CF, T4-50% PM+50%CF,T5- 25% PM + 75% CF and T6 100%CF. Highest pot yield (45.50 g/pot) and oil content (45.2%) was obtained forT5 and Maximum protein content (12.50%) was recorded for T3

Effect of local amendments as a partial substitute for phosphorus on soil quality

In a pot culture experiment different organic phosphorus sources (farmyard manure, poultry manure, vermicompost and sewage sludge) were evaluated with standard inorganic source of single superphosphate to improve soil nutrient content, all applied on equal P basis @ 34 kg P2O5 ha-1. The six treatments, including no-P (control) were replicated four times in a CRD. Groundnut was sown in each pot. The experimental results revealed that phosphorus increased the post-harvest soil nutrients availability. Highest availability of nitrogen, phosphorus, potassium and sulphur was recorded in poultry manure treatment and sewage sludge exhibited a considerable increase in available nitrogen and sulphur content
