Those of economic importance include diseases of the leaf, smuts such as corn smut, ear rots and stalk rots. [85] Northern corn leaf blight damages maize throughout its range, whereas banded leaf and sheath blight is a problem in Asia. [86] [87] Some fungal diseases of maize produce potentially dangerous mycotoxins such as aflatoxin. [60]
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 improved ...

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 ...
The Pro Farmer Crop Tour found ideal growing conditions could supercharge Iowa's corn yield
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.
As a rough guide, cereal straw releases about 10 to 15 per cent of its nutrients and pea residues release about 35 percent of their nutrients by the next year. The speed of mineralization depends on the nitrogen and lignin (fiber) content, soil moisture, temperature, and degree of mixing with the soil. N is released fairly quickly from residue ...
Food production per capita since 1961 Grain silos Rice plantation in Thailand Cambodians planting rice, 2004. Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural ...
