Improving the fermentation characteristics of corn through agronomic and processing practices
This study determined the influence of corn (Zea mays L.) hybrids, N availability, grain harvest moisture, and drying temperatures on dry-mill ethanol production. Six hybrids, ranging from 92 to 108 d in relative maturity (RM), were planted at two locations over 2 yr. One of four N fertilizer treatments were applied. Grain was hand-harvested at grain moistures of 20 and 25%. Grain was dried to ...

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 ...

Rethinking food production for a world of eight billion
The World Food Programme and the Chinese government jointlyannounced that food aid shipments to China would stop at the end of theyear. For a country where a generation ago hundreds of millions of peoplewere chronically hungry, this was a landmark achievement. Not only hasChina ended its dependence on food aid, but almost overnight it has becomethe world’s third largest food aid donor. The key ...

Economics of five wheat production systems with no-till and conventional tillage
Conventional tillage (CT) continues to be used on the vast majority of land seeded to monoculture winter wheat (Triticum aestivum L.) in the Southern Plains of the United States. In the region, wheat can be grown for either grain-only, forage-only, or for both fall–winter forage + grain (dual-purpose). This study was conducted to determine the net returns of five alternative wheat production ...

Net biome productivity of irrigated and rainfed maize–soybean rotations: modeling vs. Measurements
Estimates of agricultural C sequestration require an understanding of how net ecosystem productivity (NEP) and net biome productivity (NBP) are affected by land use. Such estimates will most likely be made using mathematical models that have undergone well-constrained tests against field measurements of CO2 exchange as affected by management. We tested a hydraulically driven soil–plant–atmosphere ...

Bumper 2011 Grain Harvest Fails to Rebuild Global Stocks
The world’s farmers produced more grain in 2011 than ever before. Estimates from the U.S. Department of Agriculture show the global grain harvest coming in at 2,295 million tons, up 53 million tons from the previous record in 2009. Consumption grew by 90 million tons over the same period to 2,280 million tons. Yet with global grain production actually falling short of consumption in 7 ...

Rising Meat Consumption Takes Big Bite out of Grain Harvest
http://www.earth-policy.org/data_highlights/2011/highlights22 World consumption of animal protein is everywhere on the rise. Meat consumption increased from 44 million tons in 1950 to 284 million tons in 2009, more than doubling annual consumption per person to over 90 pounds. The rise in consumption of milk and eggs is equally dramatic. Wherever incomes rise, so does meat consumption. As the ...

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 ...

Breeding maize for a bioeconomy: a literature survey examining harvest index and stover yield and their relationship to grain yield
The use of maize (Zea mays L.) stover as a feedstock for cellulosic biofuels production will create demand for maize hybrids with greater stover yield. It is expected that grain yield will remain the most critical trait and continue to drive hybrid sales, requiring that any increases in stover yield be made without sacrificing grain yield potential. The objective of this review was to determine ...

Response of yield heterosis to increasing plant density in maize
Genetic yield improvement in maize (Zea mays L.) has been associated with heterosis and increased tolerance to high plant densities, but the physiological processes underlying heterosis for tolerance to plant density stress have not been identified. The objective of this study was to quantify the response of heterosis for grain yield to increasing plant density, and to examine the processes ...

China’s Rising Soybean Consumption Reshaping Western Agriculture
Global demand for soybeans has soared in recent decades, with China leading the race. Nearly 60 percent of all soybeans entering international trade today go to China, making it far and away the world’s largest importer. The soybean was domesticated some 3,000 years ago by farmers in eastern China. But it wasn’t until well after World War II that the crop gained agricultural ...

Robust method for estimating grain yield in western Kenya during the growing seasons
Uncertainties caused by climate change and population explosion require suitable methods for estimating grain yield during the growing seasons. This paper evaluates the applicability of the AquaCrop model in the region of western Kenya. The objectives of the study were to: simulate the long-term maize crop yields for the region using AquaCrop model for variable climate scenarios, and estimate ...

Planting date and cultivar effects on grain yield in dryland corn production
Corn (Zea mays L.) production is gradually spreading into the Sudan savanna zone of West Africa where production is limited by erratic and inadequate rainfall. To increase corn production, production practices should be properly designed to minimize the effects of low precipitation and high temperatures that characterize the zone. A study, to determine the performance of late (120 d), early (90 ...

Potential phosphorus, potassium, and magnesium surpluses in an irrigated maize monoculture fertilized with pig slurry
Pig slurry (PS) is extensively applied to irrigated maize in nitrate-vulnerable zones of the Ebro Valley, Northeast Spain. Farmers base PS rates on the European Union (EU) Nitrates Directive (up to 170 kg N ha–1 derived from organic sources) or on maize-N requirements (about 300 kg N ha–1). The aim of the study was to assess whether these PS rates would lead to P, K, and Mg surpluses in excess of ...

Harvesting Corn Stover and Soil Quality
Corn stover, left in fields after corn grain harvest, has been identified as a potential feedstock to help supply biofuel needed to offset a portion of the 14 million barrels of oils consumed daily by the U.S. transportation sector. It was projected to supply 256 million tons of the 1.4 billion tons of biomass (232 million Mg out of 1.3 billion Mg) estimated to be available each year. Corn ...

Global Grain Stocks Drop Dangerously Low as 2012 Consumption Exceeded Production
The world produced 2,241 million tons of grain in 2012, down 75 million tons or 3 percent from the 2011 record harvest. The drop was largely because of droughts that devastated several major crops—namely corn in the United States (the world’s largest crop) and wheat in Russia, Kazakhstan, Ukraine, and Australia. Each of these countries also is an important exporter. Global grain ...

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 ...

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 ...
