Chambers and Quiggin (2000) advocate the use of state-contingent production technologies to represent risky production and establish important theoretical results concerning producer behaviour under uncertainty. Unfortunately, perceived problems in the estimation of state-contingent models have limited the usefulness of the approach in policy formulation. We show that fixed and random effects s...

The aims of this study are to measure the technical efficiency (TE) of Cambodian household’s rice production and trying to determine its main influencing factors using the stochastic frontier production function. The study utilized primary data collected from 301 rice farmers in three selected districts of Battambang by structured questionnaires. The empirical results indicated the level of hou...

This paper looks at differences in spatial and temporal variation of rice yields in China and Brazil. We find that rice yields in China have converged over time and that rice production has become more and more homogeneous. In contrast, rice yields in Brazil have diverged over time, primarily due to variations in upland rice yields. Three hypotheses are put forward to explain the different beha...

Future increases in global surface temperature threaten those worldwide who depend on rice production for their livelihoods and food security. Past analyses of high-temperature stress on rice production have focused on paddy yield and have failed to account for the detrimental impact of high temperatures on milling quality outcomes, which ultimately determine edible (marketable) rice yield and ...

In the Mekong delta, inland fishing and rice production provided a major source of income for rural communities. Since early settlement, the inhabitants have caught fish. Still, fish provides the main source of animal protein in their daily diet (Madan et al. 2005). Fish are caught in flood plains and in rice fields. The wild fish catch has declined since 1970 (Gagauan & Arce 1992), as a result...

Biobutanol produced by Clostridium spp. can be used as a biofuel and/or chemical feedstock. For cost-effective and sustainable production of biobutanol, an untapped biomass such as rice straw could be used as a substrate. Rice straw, which is composed of cellulose, hemicellulose, and lignin, is cheap and abundant. However, the utilization of rice straw is limited because butanol-producing clost...

Both Bangladesh and India over the last two decades have realised significant improvement in availability and accessibility of quality rice seeds, particularly high yielding varieties (HYVs). This translated into increased rice production in the two countries. While rice production in Bangladesh increased from about 18 million tonnes in 1990-91 to nearly 35 million tonnes in 2011-12; production...

This work investigated the production of the fungi Isaria fumosorosea and Isaria farinosa in biphasic fermentation using agro-industrial products and residues. Combinations of natural liquid substrates, alternative to the complete medium and potato dextrose medium, were evaluated. The best liquid media were sugarcane molasses + rice broth, rice broth + yeast and sugarcane molasses + yeast + ric...

background: aflatoxins are toxic fungal metabolites enable to contaminate a wide range of natural substrates. this contamination can be host-specific for different plant species. in this study, the ability of a toxigenic aspergillus parasiticus to produce various aflatoxins on major iranian cereals was evaluated with special focus on plant susceptibility to toxin production at cultivar level. m...
