| Abstract | The primary rubber-growing area in India is the west coast of Southern India. Land and soil qualities exert considerable influence on the spatial distribution and productivity of rubber in the area. Lowlands with imperfectly drained soils and lands with elevation more than 600 meters above mean sea level were found to be unsuitable for the crop. At higher elevations lower temperatures retarded the crop growth and yield. The effect of rainfall is more in its distribution rather than the quantity and the period of soil moisture deficit significantly influences rubber productivity. The highly weathered tropical soils with strong acidic reaction, gravelly clay texture, low bases and low cation exchange capacity presented no limitation for the crop. Psamments, Usterts and Ustalfs are generally not cultivated to rubber. Hydromorphic soils (Aquepts/Aquents) are also unsuitable for the crop. High available water capacity of soils, contributed by deep solum and non-gravelly clay texture, in combination with short climatic dry period resulted in better crop yield. Soil map with soil types defined according to Soil Taxonomy together with agro-climatic maps can help identify land and soils suitable for rubber cultivation. |
