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 ...

Water sharing in the Upper Niger Basin
Mali is facing a huge challenge. Promotion of food security is of top priority for which a further expansion of Office du Niger is one of the most promising options. This implies land development and additional water extraction from the Niger. At the same time water is needed for the booming energy demand. Water, however, is limitedly available and crucial to other sectors of the environment, not ...

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. ...

Multisensor Capacitance Probes for Simultaneously Monitoring Rice Field Soil-Water-Crop-Ambient Conditions
Abstract: Multisensor capacitance probes (MCPs) have traditionally been used for soil moisture monitoring and irrigation scheduling. This paper presents a new application of these probes, namely the simultaneous monitoring of ponded water level, soil moisture, and temperature profile, conditions which are particularly important for rice crops in temperate growing regions and for rice grown with ...

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 ...

Impact assessment of pre- and post-sown irrigation with Post Methanation distillery Effluent on soil health and crop yield
Field experiments were conducted to assess the optimum dilution of Post Methanation distillery Effluent (PME) to utilise as an organic nutrient source for growing rice and wheat crops. Dilution levels of distillery effluent significantly affected the biomass production as well as grain yield of rice and wheat crops. Levels of organic carbon and NPK were significantly higher in effluent treated ...

Access to Energy: Empowering India’s Rural Communities
Tucked away in the southwestern corner of Odisha in the Bay of Bengal, the village of Keragam is home to around 230 families, most of whom are farmers. They live about 30km from the nearest town, while the state capital, Bhubaneswar, is an 11-hour drive away. Those who work the land here do so in relative isolation; they grow rice and sugarcane as best they can, in a patchwork of green and brown ...

A hotter planet means less on our plates
In the Sunday November 22, 2009 issue of Outlook in the Washington Post, Lester Brown discusses the significant implications of food security in the upcoming Copenhagen Conference. As the U.N. climate-change conference in Copenhagen approaches, we are in a race between political tipping points and natural ones. Can we cut carbon emissions fast enough to keep the melting of the Greenland ice ...

How to build the perfect levee in 5 steps
In June, the rice-planting season will shift into high gear across the country. And as anyone who has worked with rice knows, it’s unique because of the irrigated conditions it’s grown in. For the crop to be a success, you need a levee that produces the right controlled flooding environment. To help you be successful this season, AMCO has created this guide to building levees that ...

Can grains of the past help us weather storms of the future?
Combining science with traditional knowledge, researchers turn to ancient rice as a source of climate resilience In May 2009, Cyclone Aila wreaked havoc in eastern India. Clocking in at speeds of over 120 kilometers per hour, Aila hit the Sundarbans, the largest continuous block of mangrove forest in the world, located in the Ganga-Brahmaputra tidal delta on the Bay of Bengal. The storm killed ...

Bt rice producing Cry1C protein does not have direct detrimental effects on the green lacewing Chrysoperla sinica Tjeder
The effects of insect‐resistant genetically engineered rice producing Cry1C protein derived from Bacillus thuringiensis (Bt) on Chrysoperla sinica Tjeder (Neuroptera: Chrysopidae) were assessed in laboratory bioassays. Survival and development of C. sinica larvae were not adversely affected when the larvae were fed a diet containing purified Cry1C protein at 200 µg/g fresh weight of diet, ...

Simulating leaf appearance in rice
Most rice (Oryza sativa L.) simulation models assume that only temperature affects leaf appearance rate (LAR). This assumption ignores results from controlled environment studies that show that LAR in rice is not constant with time (calendar days) under constant temperature. The Streck model, which takes into account age effects on LAR, improved the prediction of leaf appearance in winter wheat ...

How three U.S. mini-farms are sowing the seeds of global food security
Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...
