**4. Plantation and agroclimatic factors**

The plant can grow well in tropical and subtropical regions. It can germinate in humus and sand in comparison to red earth [5]. Loam to clay-loam soil is suitable for its cultivation and the species can grow in the soil pH upto 8.5 [9]. Okusanya et al. (1991) found that the species showed a significantly better growth in wet and moist soil conditions than dry and waterlogged conditions. They also reported that the species responded identically to pH range 3.5, 5.5 and 7.5. The plant also has salinity tolerance [5].
