Abstract
The importance of pigeon pea as forage and pulse crop 'the tropics is well established (Killinger, 1968; Herrera and Crowder. 1963; Parbery, 1967). The pigeon pea is a short-lived parrenial shrub shrub which requires just a starter nitrogen fertilizer for its establishment (Hewitt, 1958), Phosphorus is usually considered second in importance to nitrogen in limiting crop yields. Singh and Sahasrabudhe(1957)noted that application of ammonium superphosphate or compost had little effect on the yield of pigeon pea in India, and that its response to superphosphate was not generally visible,Pietri et al(1971)also reported lack of response by pigeon pea to fertilizer treatments on an oxisol in puerto Rico.In India,however,pigeon pea was reported to have responded to applied phosphorus (Chowdhury and Bhatia,1971:Veeraswamy et al,,1972)
