The effect of incubation of Single super phosphate (SSP) along with poultry litter (PL) for various period of time was investigated by growing maize and measuring P-uptake when grown in a alkaline calcarious soils in a pot culture experiment. The dry matter yield of 49 days old plants showed that 3 days incubation of SSP along with PL produced maximum yield over SSP alone. This trend was closely followed by 21-day incubation time. Phosphorus uptake by maize tops and roots were also higher SSP and PL were incubated for 3 to 21 days before application and thereby resulted in significantly higher P-fertilizer efficiency than SSP applied alone.
