title: A study of the relationship of rice cultivation and annual parasite incidence of malaria in India.
abstract: Twenty one year data (1963-1983) of 25 states/UTs of India on area under rice cultivation and annual parasite incidence was analysed using correlation and regression analysis to evaluate the relationship of irrigated area under rice cultivation and the statewise annual parasite incidence of malaria. In 23 states either the correlation is negative or non-significant whereas in Punjab and Nagaland significant positive correlation is observed. Study showed that in India at the macro level (i.e. data pooled at the state level both for rice cultivation and (API) rice cultivation by and large had poor relationship to API.
