It is common knowledge that the average acre yields in India are very far behind those countries in the East, like Japan and China or of the West, like Spain, Italy and United States of America. One of the essential features which differentiates rice growing in this country and that in the others is the period during which the bulk rice crops are grown in several countries. In the Indian Union most of the rice is monsoon crop, when high humidity and comparatively less sun-shine favourable for promoting vegetative vigour at the expense of grain formation are present. In all the other countries which record very high acre yields, rice is an autumn crop. It is grown from May to September when ideal conditions prevail for maximum out-turn. The soil and atmospheric temperature, humidity and sun-shine are optimum. The irrigation is also heavy notwith-standing good uniform rainfall available in those countries. It is no wonder, therefore, that high acre yields of rice result. In Madras where rice is grown as an autumn crop high yields comparable to those in Japan are obtained. This should not, however mean that we in India cannot improve our acre yields. Though not to the same extent as in Japan just now. our rice yields can be quite easily stepped up by pooling all the natural resources of the country and adopting better cultural methods, to enhance the present average by at least another 50 per cent more. By research high yielding strains of rice have been produced. The experiences gained on the optimum use of manures and the adoption of the best cultural practices and other useful information for increasing rice production have not reached all the cultivators in proper perspective due to diverse causes.
