  2. Crop yield - Wikipedia

    en.wikipedia.org/wiki/Crop_yield

    In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. The seed ratio is another way of calculating yields. Innovations, such as the use of fertilizer , the creation of better farming tools, new methods of farming and improved crop varieties , have ...

  3. Corn ethanol - Wikipedia

    en.wikipedia.org/wiki/Corn_ethanol

    In the United States, 40% of the acreage designated for corn grain is used for corn ethanol production, of which 25% was converted to ethanol after accounting for co-products, leaving only 60% of the crop yield for human or animal consumption. [30] Growing corn to fuel internal combustion vehicles is a highly inefficient use of land.

  4. Land equivalent ratio - Wikipedia

    en.wikipedia.org/wiki/Land_equivalent_ratio

    Land equivalent ratio. The FAO defines land equivalent ratio (LER) as: [2]. the ratio of the area under sole cropping to the area under intercropping needed to give equal amounts of yield at the same management level.

  5. Corn production in the United States - Wikipedia

    en.wikipedia.org/wiki/Corn_production_in_the...

    The US is the world's largest producer of corn. [8] According to the United States Department of Agriculture (USDA), the average U.S. yield for corn was 177 bushels per acre, up 3.3 percent over 2020 and a record high, with 16 states posting state records in output, and Iowa reporting a record of 205 bushels of corn per acre.

  6. Corn oil - Wikipedia

    en.wikipedia.org/wiki/Corn_oil

    Almost all corn oil is expeller-pressed, then solvent-extracted using hexane or 2-methylpentane (isohexane). [1] The solvent is evaporated from the corn oil, recovered, and re-used. After extraction, the corn oil is then refined by degumming and/or alkali treatment, both of which remove phosphatides. Alkali treatment also neutralizes free fatty ...

  7. Corn stover - Wikipedia

    en.wikipedia.org/wiki/Corn_stover

    Corn field in Liechtenstein. Corn stover consists of the leaves, stalks, and cobs of corn (maize) (Zea mays ssp. mays L.) plants left in a field after harvest. Such stover makes up about half of the yield of a corn crop [1] and is similar to straw from other cereal grasses; in Britain it is sometimes called corn straw. Corn stover is a very ...

  8. Ethanol fuel energy balance - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel_energy_balance

    In Brazil where sugar cane is used, the yield is higher, and conversion to ethanol is more energy efficient than corn. Recent developments with cellulosic ethanol production may improve yields even further. [12] In 2006 a study from the University of Minnesota found that corn-grain ethanol produced 1.25 units of energy per unit put in. [13]

  9. Corn syrup - Wikipedia

    en.wikipedia.org/wiki/Corn_syrup

    Corn syrup is a food syrup which is made from the starch of corn/maize and contains varying amounts of sugars: glucose, maltose and higher oligosaccharides, depending on the grade. Corn syrup is used in foods to soften texture , add volume, prevent crystallization of sugar, and enhance flavor.
