The only other important plantation crop is rubber, the systematic cultivation of which began as recently as 1900. There are only two tracts in which the climatic conditions are suitable for the growth of rubber on a commercial scale, namely, certain parts of Burma and the Malabar coast below the Western Ghats from Mangalore to Cape Comorin. The total yield, including the Indian States, is about 28 million lbs., of which Burma and Travancore each produces about 11 million lbs. The province of Madras accounts for only about 3 million lbs., and in Coorg the yield of rubber is a little over half a million lbs.
