During this period, their FCR is 3.5. [16] Their FCR begins increasing gradually after this period. For instance, in the US as of 2012 [update] , commercial pigs had FCR calculated using weight gain, of 3.46 for while they weighed between 240 and 250 pounds, 3.65 between 250 and 260 pounds, 3.87 between 260 and 270 lbs, and 4.09 between 280 and ...
The land equivalent ratio can be used whenever more than one type of yield can be obtained from the same area. This can be intercropping of annual crops (e.g. sorghum and pigeonpea ) [ 1 ] or combination of annual and perennial crops e.g. in agroforestry systems (e.g. jackfruit and eggplant ).
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.
Since corn is a major input cost to hog producers, the higher the price of hogs relative to corn, the more profit there is in feeding hogs. [1] In dairy farming, the milk-feed price ratio is a measure of the value of 16% protein ration to one pound of whole milk. As with the hog/corn ratio, this relationship is an indicator of the profitability ...
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]
It is typically used for grain commodity stocks such as wheat, corn and soybeans where it can be used to compare both the ending stock, along with the stocks-to-use ratio against previous years, this percentage number is a good indicator of whether current ending stock levels are at historically small amounts to justification for higher prices ...
The maximum sustainable yield is the largest yield that can be taken from a population at equilibrium. In figure 3, if H {\displaystyle H} is higher than H 2 {\displaystyle H_{2}} , the harvesting would exceed the population's capacity to replace itself at any population size ( H 3 {\displaystyle H_{3}} in figure 3).
