In order to increase the quality of locally produced rice, the artisanal parboiling process in West and Central Africa was reconceptualized. A novel parboiling unit was constructed using stainless steel (Inox 304) and fitted directly on an improved stove made from fired bricks. The heat profile at different locations in the unit, the physicochemical properties, cooking properties of the parboil...

in this research, rice husk and activated carbon adsorbents were used for removal of lead ion from aqueous solution at ph= 6. in the batch tests experimental parameters were studied, including contact time and initial metal ions concentration.survey of the equilibrium time at different concentration showed that equilibrium time is reduced with decrease of initial concentration of solution from ...

This study computes the eco-efficiency of High Yielding Variety (HYV) rice production by including an on-farm environmental damage index (OFEDI) as an undesirable output using Data Envelopment Analysis (DEA) and then identifies its determinants by applying an interval regression procedure on a sample of 317 farmers from north-western Bangladesh. Results reveal that the mean level of the OFEDI-a...

an experiment was conducted to study the effects of an emulsifier (glycerol polyethylene glycol ricinoleate: gpgr) and different sources of fat on the performance of khaki campbell ducks. ducks were assigned into five groups with three replicates (10 ducks/replicate) in each group. treatments were a control diet (c1: without added oil and emulsifier), control diet added with 2% soybean oil (c2)...

To break the yield ceiling of rice production, a super rice project was developed in 1996 to breed rice varieties with super high yield. A two-year experiment was conducted to evaluate yield and nitrogen (N)-use response of super rice to different planting methods in the single cropping season. A total of 17 rice varieties, including 13 super rice and four non-super checks (CK), were grown unde...

In Japan, greenhouse gas emissions from rice production, especially CH4 emissions in rice paddy fields, are the primary contributors to global warming from agriculture. When prolonged midseason drainage for mitigating CH4 emissions from rice paddy fields is practiced with environmentally friendly rice production based on reduced use of synthetic pesticides and chemical fertilizers, Japanese ric...

more than 50% of the global population already lives in urban settlements which are projected to absorb almost all the global population growth to 2050, amounting to some additional three billion people. over the next decades the increase in rural population in many developing countries will be overshadowed by population flows to cities. rural populations globally are expected to peak at a leve...

pressurized irrigation is a recent development that consumes more energy for the pressure produced. in thisstudy, energy consumption, waste and efficiency were investigated at a diesel and electrical sprinklerirrigation pumping plant in some fields in hamadan province during 2007-8. nebraska performance criteria(npc) were used to compare sprinkler irrigation pumping plant performance. the resul...

White rice is a dominant grain-based food in Japan, but excess intake of polished rice may cause obesity. Barley is a grain-based food, similar to white rice, but it has the potential to control appetite and reduce energy intake. We investigated the effect of cooked white rice with high β-glucan barley on appetite and energy intake. The study was conducted as a randomized crossover design with ...

Bush bean, long bean, mung bean, and winged bean plants were grown with N fertilizer at rates of 0, 2, 4, and 6 g N m(-2) preceding rice planting. Concurrently, rice was grown with N fertilizer at rates of 0, 4, 8, and 12 g N m(-2). No chemical fertilizer was used in the 2nd year of crop to estimate the nitrogen agronomic efficiency (NAE), nitrogen recovery efficiency (NRE), N uptake, and rice ...
