Meeting the challenges of global rice production
Rice is the second most widely grown cereal crop and the staple food for more than half the world’s population. More than 3 billion people consume more than 100 kg of rice per year. Rice is cultivated on 155.5 million ha with an average growth rate of 0.39% a year, in the last 30 years. In the near future, the possibility for expanding areas under rice based systems will remain very limited ...

Assessing the regional food insecurity in Bangladesh due to irrigation water shortage in the Teesta catchment area
Bangladesh is losing huge food production from the Teesta catchment area due to a lack of availability of irrigation water in the dry and lean period because of unilateral water withdrawal in the upstream country, India. The area, which is directly dependent on the irrigation water of the Teesta river, is the study area for this paper. The study reveals that rice production in Dalia, ...

Salinity-induced loss and damage to farming households in coastal Bangladesh
Salinity intrusion in soil caused by climate-induced hazards, especially cyclones and sea level rise (SLR), is adversely affecting rice production in coastal Bangladesh. The southwest coastal district of Satkhira is one of the most vulnerable areas because of its high exposure to salinity intrusion and widespread poverty. Based on a survey of 360 farming households in four villages and on focus ...

Accounting for the market and non-market values of multifunctional outputs in evaluating water transfers to non-agricultural uses: empirical evidence from Taiwanese rice production
Increased demand for water for municipal and industrial uses throughout Taiwan has intensified the pressure to re-allocate water from agricultural to non-agricultural uses. The full policy implications of such water transfers must not only account for the value of lost agricultural production and income, but also any loss in the social value of multifunctional benefits from agricultural ...

Influence of Capacity Building on Technical Efficiency of vegetables and rice farmers in Bangladesh: JICA intervention in Comilla project
This study examines the influence of Capacity Building (CB) on Technical Efficiency (TE) of farming community in the Comilla project area, Bangladesh, which occurred due to the intervention of Japan International Cooperation Agency (JICA). The results indicated a significant variation in TE of vegetable and rice Production Inside (IP) and outside the project area. The farmers with low-, medium- ...

Basic Information of Rice Production Line
The objective of a rice milling system is to remove the husk and the bran layers from paddy rice to produce whole white rice kernels that are sufficiently milled, free of impurities and contain a minimum number of broken kernels. The milling yield and quality of rice is dependent on the quality of the paddy, the milling equipment used and the skill of the mill operator. With the rapid upgrading ...

Challenges and opportunities for a sustainable rice production in Europe and Mediterranean area
Rice is the second largest cereal crop grown worldwide. One-half of the world population and virtually all of East and Southeast Asia is wholly dependent upon rice. Rice production in the Mediterranean regions dates back to the seventh century. This crop was first introduced into Egypt and gradually spread, towards the fifteenth century, to most countries of the Mediterranean basin. Rice is at ...

Rice production with minimal irrigation and no nitrogen fertilizer by intensive use of treated municipal wastewater
We designed a new cultivation system of rice with circulated irrigation to remove nitrogen from treated municipal wastewater effectively and assessed the possibility of nitrogen removal in the new system without any adverse effects on rice production through bench-scale experiments through two seasons. Overgrowth of the rice plant, which can lead to lodging and tasteless rice, was found in the ...

Genotype x environment interactions of hybrid and varietal rice cultivars for grain yield and milling quality
The study of genotype x environment interaction is critical for accurate cultivar evaluation in large multi-environment trials. Cultivars that exhibit high levels of mean performance and stability across a wide range of environmental conditions are desirable for rice production. Pure-line varietal and hybrid rice cultivars are commercially produced in the U.S.; however, little research has been ...

Hybrid rice response to nitrogen fertilization for midsouthern united states rice production
Limited data representing the southern U.S. production area exists for N nutrition in hybrid rice (Oryza sativa L.) cultivars. Experiments were conducted to evaluate the effects of N fertilizer rates and application timings on grain and whole milled rice yield for ‘XL723’ (RiceTec, Inc., Alvin, TX) as compared with widely grown inbred rice cv. Cocodrie on clay soils and Cheniere on silt loam ...

The California rice cropping system: agronomic and natural resource issues for long-term sustainability
California rice is produced on approximately 200,000 ha mostly in the Sacramento Valley. The crop is planted in April/May and harvested in September/October. The growing season is characterized by a Mediterranean climate with negligible rainfall, high solar radiation, and relatively cold nighttime temperatures, thus yields may exceed 9 t ha−1, 20% above the US average. California is a ...

Transferring irrigation management to farmer's associations: Evidence from the Philippines
Irrigation management transfer (IMT) is an important strategy among donors and governments that aims to strengthen farmer control over water and irrigation infrastructure. In this study, we use data from a survey of 68 irrigator associations (IAs) and 1020 farm households in the Philippines to examine the impact of IMT on irrigation association performance and on rice yields. We find that the ...

Grain yield performance of selected lowland NERICA and modern asian rice genotypes in West Africa
Six lowland experiments were conducted over three years in southern Benin to assess yield differences in 28 rice (Oryza spp.) genotypes grown under nonfertilized and fertilized conditions. These included the interspecific hybrids, the lowland New Rice for Africa (NERICA) genotypes developed from crossing O. sativa and O. glaberrima. Fertilizer rates were 70–86N: 30–37P2O5: 30–37K2O kg ha–1. ...

Soil salinity and exchangeable cations in a wastewater irrigated area, India
Received for publication May 29, 2008. The salinity and cation composition of water and soil were documented in a large (98 km2) wastewater-irrigated area (WIA) downstream of Hyderabad, India. The wastewater, which flows in a river that passes through the city, had a high to very high salinity hazard (EC = 1.1–3.0 dS m–1) that increased with distance from the city. The EC of soil irrigated by ...

Correlation and calibration of soil potassium availability with rice yield and nutritional status
Soil testing is an important tool for estimating soil K availability and determining how much fertilizer must be applied to realize crop yield potential and minimize fertilizer costs. Our primary objectives were to correlate relative rice (Oryza sativa L.) yield with Mehlich-3 and 1 mol L–1 HNO3 extractable K, define sufficient whole-plant K concentrations at panicle differentiation (PD) and ...

Japanese sake-brewing rice cultivars show high levels of globulin-like protein and a chloroplast stromal HSP70
White-core is an important trait in the selection of rice (Oryza sativa L. ssp. japonica) for sake (Japanese rice wine) production. The present study was conducted to find differences between the endosperm protein pattern of white-core–bearing sake-brewing cultivars and those of normal rice grains. Protein patterns of white-core sake-brewing grains were compared with those of normal cultivars by ...

Nitrogen removal and power generation from treated municipal wastewater by its circulated irrigation for resource-saving rice cultivation
This study aims at improving the performance of the cultivating system of rice for animal feed with circulated irrigation of treated municipal wastewater by applying a larger amount of wastewater, as well as adding a microbial fuel cell (MFC) to the system. The results of bench-scale experiments indicate that this modification has increased the rice yield, achieving the target for the rice ...
