less than 7 kg/month. At higher income levels,
per-caput consumption declines. About SO percent
of India's population has a monthly income
of less than Rs 15. Hence, population and income
growth in India will continue to place heavy
strains on demand for coarse grains.
Growth in coarse-grain production in India
has not kept pace with demand during the last 20
years despite introduction of HYVs. In 1971,
production was estimated to have fallen behind
demand by 1.7 million tons. If these trends
continue, the shortfall could be around 4 million
tons by 198S. To meet this from local production
will require an annual production growth of 3.2
percent per annum. It seems if this increase is to
be achieved, yields per hectare must rise as land
for expanding the area under coarse grains is
very limited.
