Cultivation Details
A plant of the drier tropics, where it is found at elevations up to 2,000 metres. It grows best in areas where annual daytime temperatures are within the range 21 - 36°c, but can tolerate 8 - 40°c[1]. The plant does not tolerate frost. It prefers a mean annual rainfall in the range 650 - 900mm, but tolerates 500 - 1,250mm[1]. Prefers a sunny position, tolerating light shade[1]. Grows well in a sandy loam[2]. Prefers a pH in the range 5.5 - 6.2[1]. Established plants are moderately drought resistant[2]. A plant for light or moderate rainfall areas[2]. Pods can be harvested 3 - 5 months after sowing, though yields are relatively low[2]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[3]. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.
