SOME EFFECTS OF RICE QUALITY ON ROUGH RICE PRICES
No full textQuality discounts and premiums for rough rice in Texas rice bid/acceptance markets are analyzed. The most important quality factors determining the value of rough rice are head yield and peck. A one percentage point reduction in peck damage raises the price received per hundredweight of rough rice by .68 across markets and years. Since peck damage can be reduced by controlling the rice stinkbug, evaluation of alternative methods for better control of this pest in Texas rice fields is needed.Demand and Price Analysis,

No full textComparative studies on calothrix isolates from Nepalese rice-fields
No full textAlgal samples were collected from three rice-fields in Nepal: A) Parwanipur (100 m), B) Khumaltar (1336 m) and C) Kakani (2064 m); the rice- field algal flora from 1982, 1983 and 1986 samples was recorded. Three Calothrix strains were isolated from 1986 samples, one from each of the three sites, as representatives of the rice-field flora. A study was carried out on morphology of these Calothrix isolates, in particular, the influence of phosphorus deficiency on morphology. Starting with hormogonium production, morphological changes were followed in one set of cultures without any further addition of phosphate and in another set, 10 mg 1(^-1) P was added to P-limited cultures. With increase in phosphorus deficiency, synthesis of hormogonia ceased in all the strains, with obvious increase in cyanophycin granules and decrease in polyphosphate granules. Formation of intercalary heterocysts in Calothrix D794 and D795 and separation discs in Calothrix D796 was followed by the formation of intra-thylakoidal vacuoles and false-branches in all, but no hair cells formed in any strain. The addition of further phosphate to P-limited cultures led to renewed synthesis of hormogonia within 18 h in all strains. The effect of light flux and nutrient concentration on morphology of three strains was tested. The effect of change in light flux on gas vacuole formation was examined in Calothrix D794. Gas vacuoles continued to form but at a lower rate when the alga was shifted to 170 pmol photon m(^-2)s(^-1) after initial period of incubation in dark. Gas-vacuolated hormogonia formation, release and disappearance of gas vacuoles in free hormogonia occurred within two hours of exposure to 170 \mol photo m(^-2)s(^-1)
Rice World Market Prices
No full textThe marketing loan program associated with rice features benefits calculated using a USDA-announced World Market Price (WMP) rather than the posted county prices that are used for most other commodities. This results in reduced risk protection for producers relative to other crops, and greater difficulty in making optimal use of program benefits. This research investigates the rice WMP, identifying the relative importance of various foreign prices and other potential influencing factors. The results of this research have important implications for financial planning and optimal risk management strategies for rice producers.Agricultural and Food Policy,
THE RESPONSIVENESS OF U.S. RICE ACREAGE TO PRICE AND PRODUCTION COSTS
No full textOrdinary least squares and seemingly unrelated regression procedures were used to analyze the impacts of changes in rice prices and production costs on U.S. rice planted acreage. National and regional response models were estimated over the 1970-92 period. Supply-inducing prices of rice were estimated as a function of effective rice support prices and seasonal average market prices. Expected production costs per acre were estimated using lagged actual total variable cash production expenses per acre adjusted by the previous 3-year average annual change in variable expenses. Estimated short-run price and production cost elasticities were found to be inelastic at the national level. However, the magnitude of the production cost elasticities were found to be greater than the price elasticities. Estimated long-run elasticities at the U.S. level were inelastic for changes in price but elastic for changes in production costs. Although acreage response varied across regions, similar relationships were found between price and production cost elasticities.Rice, Acreage response function, Price elasticity, Crop Production/Industries,
Socioeconomics of rice-aquaculture and IPM in the Philippines: synergies, potential and problems
No full textRice farming covers nearly one-third of the arable land of Asia. The study shows results that are useful for policymakers wishing to promote new diversification opportunities in the crop sector. It describes some of the complexities in understand farming households and farm labor use and how people make decisions on what crops to grow, how to allocate family labor and how best to feed the family. The study goes beyond fish farming in rice fields to include the role of naturally occurring aquatic organisms in rice fields such as frogs, snails and wild fish.Rice-fish aquaculture, Integrated farming, Pest control, Small scale aquaculture, Socioeconomic aspects, Philippines,
Golden Rice and the Looming GMO Trade Debate: Implication for the Poor
No full textThe first generation of genetically modified crop varieties, currently most widespread in the maize and soybean sectors, sought to increase farmer profitability by improving agronomic traits. The next generation of biotech research is focusing also on breeding for attributes desired by consumers. Although not yet commercially available, a new variety of rice, known as ‘Golden Rice’, has been genetically engineered to contain a higher level of vitamin A. Thus in contrast with the current commercial applications of biotech crops, this new rice variety aims directly at benefiting consumers rather than producers. More specifically, it aims at improving the health of poor people in developing countries who rely on rice as their main staple food (or would be if it was cheaper) and whose diet is nutrient-deficient. This paper analyses empirically the potential economic effects of such an innovation in an environment of heated debates about the risks and benefits of these biotech developments. The emergence of genetically modified foods is generating policy reactions that are delaying the development and adoption of what promises to be a high-payoff technology, particularly for the world’s poor. These policy reactions may lead to trade disputes, in which case the way this GMO issue is addressed in the WTO’s dispute settlement body could have profound implications for poor households in developing countries.GMOs, golden rice, rice policy, WTO agreements, consumer preferences
