A village was selected from agro-climatic zone-5 in Punjab (India) to assess energy-resource availability, expenditure and shortcomings of the village ecosystem. Data on energy inputs and outputs were collected over a period of two years. The village had a gross power of 3.9 kW/ha and the...

Energy inputs and crop yields of rice by 209 farmers from three villages were collected over 2 years and analysed. Relations were found between crop yield and tillage, irrigation, fertilizers, and pre-harvest or total energy inputs. The 209 farmers were divided into 25 homogeneous groups by...

The paper considers a problem of estimating a finite population parameter T (α, β, γ) in two-phase and successive sampling. Asymptotic optimum estimator (AOE) in a class is identified with its approximate variance formula. Several estimators of different parameters are identified as...

In this paper, a new randomized response device is proposed based on the use of negative hypergeometric distribution while estimating the proportion of persons possessing a sensitive characteristic in a population. Situations where the proposed randomization device can perform better than the...
