Productive efficiency for Chinese hybrid and conventional rice production is estimated using a dual stochastic frontier efficiency decomposition model. Results reveal significant differences in technical and allocative efficiency between conventional and hybrid rice production, and indicate significant regional efficiency differences in hybrid rice production, but not in conventional rice produ...

Arsenic concentration in raw rice is not only the determinant in actual dietary exposure. Though there have been many reports on arsenic content in raw rice and different tissues of rice plant, little is known about arsenic content retained in cooked rice after being cooked following the traditional cooking methods employed by the people of arsenic epidemic areas. A field level experiment was c...

The population of the Ganges Brahmaputra Meghna (GBM) delta is highly vulnerable to food insecurity and malnutrition due to the specific environmental, climatic and human development factors affecting agricultural production and fisheries. To better understand the impacts of climate and environmental change on food security and nutrition in this delta, this study combines spatially explicit dat...

More and more people in Bangladesh have recently become aware of the risk of drinking arsenic-contaminated groundwater, and have been trying to obtain drinking water from less arsenic-contaminated sources. In this study, arsenic intakes of 18 families living in one block of a rural village in an arsenic-affected district of Bangladesh were evaluated to investigate their actual arsenic intake vi...

Fifty rice varieties collected under different categories from various sources were grown at the BRRI field during the 2001 transplant aman season ( July–November). Precautions were taken during harvest and processing to prevent mineral contamination. All samples were hand-pounded before being analyzed for iron and zinc content. The iron and zinc content varied considerably within the different...

the purpose of this study is calculate the rate of total factor productivity (tfp) growth  of rice varieties for different provinces of  iran and then breakdown it to the changes in a technology, management efficiency and scale efficiency. for this purpose we use the nonparametric method of comprehensive data analysis and malmquist productivity index. the used data include the rice varieties pr...

My first view of Bangladesh was in 1977 when I joined the staff of the R.I.H.D. Hospital, classified as a Technical Assistant for the Overseas Development Ministry it reverted to an Administration in the Foreign Commonwealth Ministry with the return of the Conservative Government in 1979. These appointments are financed by the O.D.A. and an orthopaedic surgeon can usually manage only a 4 to 5 w...
