In successive sampling with partial replacement, an estimator is proposed for the population mean on the second of two successive occasions utilising information available on both the occasions on an auxiliary variate with an unknown population mean. It is shown that the proposed estimator is more efficient than the sample mean and the estimators considered by Sen (1971). An empirical study is also included.

The economic viability of rice-fish culture practiced by the fanners of Assam in NorthEastern part of India was evaluated using techno-economic approach. The fanners followed extensive level farming practice using low input technology. Cobb-Douglas production function was used to detennine the input-output relationship of the system. The cost and return evaluation shows that rice-fish culture can be a more profitable option than monoculture of paddy.
