Meteorological data for four contrasting chickpea-growing locations--Hisar and Hyderabad in India, Aleppo in Syria, and Khartoum in Sudan are given. In India, pigeonpea-growing areas are usually located in regions with a 600-1400 mm annual rainfall and a growing period of 90-180 days. Chickpea is usually grown where mean daily maximum temperatures are 22.5-30 degrees C and mean daily minimum temperatures 7.5-13 degrees C during January, when flowering begins. The soils on which the two crops are grown are predominantly Alfisols, Entisols, Inceptisols, and Vertisols. At Patancheru, in a medium-deep Vertisol having 150 mm water-storage capacity, the simulated available soil water in 70% of the years studied was 120 mm under rainy-season fallow and 80 mm under rainy-season sorghum. At Hisar, the simulated available soil water after rainy season fallow in 70% of the years was more than 120 mm in soils with 150 mm water-storage capacity. Using the water use and yield relationship, cumulative probabilities of chickpea yields and phosphorus requirements were computed for both ICRISAT Center and Hisar. Although simulated yields were higher than farmers' yields, the water use and yield relationships can be used to compute the probabilities of potential yield at various locations. The delineation of the isoclimes of pigeonpea-growing areas in West Africa is also reported.
