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. Cereal yield in tons per hectare and kilograms of nitrogenous fertilizer applied per hectare of cropland.
Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of outputs to inputs. [2] FCR is widely used in hog and poultry production, while FE is used more commonly with cattle. [2]
It is the sum of the fractions of the intercropped yields divided by the sole-crop yields. For a scenario where a total of m {\displaystyle \textstyle m} crops are intercropped, the land equivalent ratio LER can be calculated as
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.
For example, in pig farming, the hog/corn ratio is the number of bushels of corn equal in value to 100 pounds of live hogs. Put another way, it is the price of hogs, per hundredweight, divided by the price of corn per bushel. Since corn is a major input cost to hog producers, the higher the price of hogs relative to corn, the more profit there ...
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 ...
In 1995 the USDA released a report stating that the net energy balance of corn ethanol in the United States was an average of 1.24. It was previously considered to have a negative net energy balance. However, due to increases in corn crop yield and more efficient farming practices corn ethanol had gained energy efficiency. [3]
Sustainable yield is the amount of a resource that humans can harvest without over-harvesting or damaging a potentially renewable resource. [1]In more formal terms, the sustainable yield of natural capital is the ecological yield that can be extracted without reducing the base of capital itself, i.e. the surplus required to maintain ecosystem services at the same or increasing level over time.
