"Fertilizer phosphorus (P) use on Vertisols of the semi-arid zone in India is becoming more common, so it is important that for developing P management strategies the residual value of P is allowed. Little information is available on this aspect for crops such as sorghum under rainfed cropping. A field experiment was conducted for three years to study the response of sorghum to fertilizer P (0, 10, 20, and 40 kg P ha-1) in the absence and presence of P residues from the preceding year on a Vertisol (Typic Pellustert), low in extractable P (0.4 mg kg-1 soil Olsen-P). Despite the variable rainfall received during the cropping season (June-September), P applied in the previous season had strong residual effects. Sorghum yield and P uptake in treatments in which P was applied at 20 or 40 kg P ha-1 once in two years was at par with or higher than in treatments in which 10 kg or 20 kg P ha-1 was added every year. Ninety percent relative grain yield was achieved at about 20 kg ha-1 of fresh P and the results presented show that application of 40 kg P ha-1 once in two years can satisfactorily meet the P requirement of sorghum on the Vertisol."^^ .
