OAR@ICRISATAnalysis of growth and yield of extra-short-duration Pigeonpea (cajimus cajan [l.] millsp.)in relation to soil moisture availability N HNamauthorPigeonpea (Cajanus Cajan [L.] Millsp.) ranks sixth in area and production in comparison to other grain legumes worldwide and is one of the most important grain legume crops of the tropics and sub-tropics (Nene & Sheila 1990). The crop is reputed to be well adapted to marginal conditions arid can produce an economic yield in soils characterized by moisture deficits (Pathak 1970; Whiteman etal. 1985; Troedson etal. 1990). Traditional pigeonpea varieties are normally grown under rainfed conditions after the beginning of a rainy season, mostly as an intercrop, and most of their reproductive growth relies on stored soil moisture in the following postrainy season. Although these varieties have a deep and extensive root system (Rachie & Roberts 1974; Sheldrake & Narayanan 1979) which enables them to avoid drought, they have been shown to suffer from terminal drought stress due to progressive depletion of residual soil rrioisture in the postrainy season (ICRISAT 1984; Muchow 1985a; Singh & Subba Reddy 1988).Pigeonpea1994-04-25Ministry of Education and Training Government of Vietnam;AgronomyThesis
