Abstract
The importance of pigeon pea as forage and pulse crop in the tropics is well established (Killinger, 1968; Herrera and Crowder, 1963; Parbery, 1967). The pigeon pea is a short-lived perennial shrub which requires just a starter nitrogen fertilizer for its establishment (Hewit 1958). Phosphorus is usually considered second in importance to nitrogen in limiting crop yields. Singh and Sahasrabudhe (1957) noted that application of ammonium super phosphate or compost had little effect on die yield of pigeon pea in India, and that its response to superphosphate was not generally visible. Pietri et oJ. (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 Bhabia, 1971;Veeraswamy et al .• 1972).
