CERAMIC GRAINS
The alumina abrasive having a microcrystalline structure obtained by the gel method is called the ceramic grains. Through special processing, each grain has thousands of tiny crystals. This structure brings the very good self-sharpness performance of the grains, which can continuously reveal new and sharp cutting edges. RIKEN RMC Ceramic grains are very dense, rough, strong and sharp. When worn, ...

Data Highlight: Arab Grain Imports Rising Rapidly
The Arab countries in the Middle East and North Africa make up only 5 percent of the world’s population, yet they take in more than 20 percent of the world’s grain exports. Imports to the region have jumped from 30 million tons of grain in 1990 to nearly 70 million tons in 2011. Now imported grain accounts for nearly 60 percent of regional grain consumption. With water scarce, arable ...

Hormonal changes caused by the xenia effect during grain filling of normal corn and high-oil corn crosses
The xenia effect results from the cross-fertilization of nonrelated lines of crops, which causes a grain to produce a germ or embryo that is much larger than average. It is a significant genetic component in TopCross grain production systems, which can affect grain yield and quality. This study measured hormone variations during grain filling of normal corn (Zea mays L.) hybrids, and normal corn ...

Efficacy of herbicide seed treatments for controlling striga infestation of sorghum
Witchweed (Striga spp.) infestations are the greatest obstacle to sorghum [Sorghum bicolor (L.) Moench] grain production in many areas in Africa. The objective of this study was to evaluate the efficacy of herbicide seed treatments for controlling Striga infestation of sorghum. Seeds of an acetolactate synthase (ALS) herbicide–tolerant sorghum hybrid were treated with two ALS-inhibiting ...

Seeds of change in sub-Saharan Africa
In the late 1900s, as per-acre grain yields moved to 3 metric tons per hectare in South and Southeast Asia and Latin America, 5 metric tons per hectare in China, and 10 metric tons per hectare in North America, Europe and Japan, there’s one place where production stagnated big time: sub-Saharan Africa, where loss of soil fertility on small farms trapped grain production at an unsustainable ...

Estimating genetic coefficients for the CSM-CERES-Maize model in North Carolina environments
CSM-CERES-Maize has been extensively used worldwide to simulate corn growth and grain production, but has not been evaluated for use in North Carolina. The objectives of this study were to calibrate CSM-CERES-Maize soil parameters and genetic coefficients using official variety trial data, evaluate model performance in North Carolina, and determine the suitability of the fitting technique using ...

Optimizing stocking rate for maximum return to a wheat–cattle enterprise using model simulation and economics
Managing dual-purpose wheat is complex because of the tradeoff relationship between cattle (Bos taurus) and wheat (Triticum aestivum L.) production. Stocking rate (SR) and planting date are key decision variables of the dual systems. The objective was to develop decision support information that help farmers boost profits by adapting SR and planting date to particular production and market ...

Grain Yields Starting to Plateau
By Lester R. Brown From the beginning of agriculture until the mid-twentieth century, growth in the world grain harvest came almost entirely from expanding the cultivated area. Rises in land productivity were too slow to be visible within a single generation. It is only within the last 60 years or so that rising yields have replaced area expansion as the principal source of growth in world grain ...

Effect of nitrogen application on yield and quality of silage corn after forage legume-grass
Decomposition of forage legume-grass (FLG) sods after turnover will supply N to the next corn (Zea mays L.) crop. For optimum economic grain production typically a starter N application is sufficient. However, the impact of eliminating sidedress N on yield and quality of silage corn in the year after sod turnover (FYC) is not well documented and little is known about the effects of timing of sod ...

Hierarchical modelling applied to agriculture: wheat planting decisions in the Pacific Northwest
This paper presents a hierarchical decision model that predicted Alturas soft white spring wheat would be the best spring wheat variety to plant in the Pacific Northwest in 2006. Profitability depends on changing market demands and competition with other crops. The challenge of wheat farming is sustaining profitability. A four level hierarchical decision model approach was selected for this ...

Capabilities of four novel warm-season legumes in the southern great plains: Grain production and quality
Grain legumes could serve as a low cost nitrogen (N) and energy source for animal production in the southern Great Plains (SGP). This study evaluated the yield and nutritive value of grains of tropical annual legumes novel to the SGP. Included were cultivars of pigeon pea [Cajanus cajan (L.) Millsp.] (cv. GA-2), guar [Cyamopsis tetragonoloba (L.) Taub.] (cv. Kinman), cowpea [Vigna unguiculata ...

Synthetic nitrogen fertilizers deplete soil nitrogen: a global dilemma for sustainable cereal production
Received for publication December 19, 2008. Cereal production that now sustains a world population of more than 6.5 billion has tripled during the past 40 yr, concurrent with an increase from 12 to 104 Tg yr–1 of synthetic N applied largely in ammoniacal fertilizers. These fertilizers have been managed as a cost-effective form of insurance against low yields, without regard to the inherent effect ...

Evaluation of management practices for grain amaranth production in eastern canada
Grain amaranth (Amaranthus spp.) is a C4 dicotyledonous pseudocereal crop that was widely cultivated in pre-Columbian America. It was successfully introduced in many regions with contrasting environmental conditions. The introduction of grain amaranth in eastern Canada would represent an opportunity for diversification. A study was conducted to evaluate management practices for grain amaranth ...

Long-term agronomic performance of organic and conventional field crops in the mid-atlantic region
Despite increasing interest in organic grain crop production, there is inadequate information regarding the performance of organically-produced grain crops in the United States, especially in Coastal Plain soils of the mid-Atlantic region. We report on corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and wheat (Triticum aestivum L.) yields at the USDA-ARS Beltsville Farming Systems Project ...

Chilling effects during maize tassel development and the lack of compensational plasticity
Stress during tassel formation can reduce tassel size and cause insufficient pollen production in seed production. When stresses affect plant development, component compensation for grain yield is known to occur in some crops. Tassel component compensation for pollen production has not been previously reported. Chilling was imposed on two dent maize (Zea mays L.) inbreds (103 and 113 relative ...

Boost grain preservation before production
Better grain storage would save money and feed over a billion, says Digvir S. Jayas. It deserves more attention. Annually over 2.6 billion tonnes of grains — cereals, oilseeds and pulses — are grown and then stored along the chain from producers to consumers. Most countries do not systematically report how much grain becomes unfit for human consumption during storage, but anecdotal ...

Breeding effects on grain filling, biomass partitioning, and remobilization in mediterranean durum wheat
This work assesses the changes resulting from durum wheat (Triticum turgidum L. var. durum) breeding in Italy and Spain during the 20th century on grain filling, biomass production, and allocation at anthesis, and the remobilization of preanthesis photosynthates to the grain of main stems. Field experiments, involving 12 Italian and 12 Spanish cultivars released at different periods, were ...

Plan B 4.0 by the numbers - data highlights on the global food supply
World agriculture today faces pressure from many sources. On the production side, the amount of unused arable and worldwide has dwindled. Overworked soils are becoming eroded and degraded, and overpumped aquifers are being depleted. Meanwhile, as the global population grows and increasing biofuel production converts grain into fuel for cars, demand for food continues to climb. In Chapters 2 and 9 ...
