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.
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 ...
Intercropping can increase yields or reduce inputs and thus represents (potentially sustainable) agricultural intensification. However, while total yield per unit land area is often increased, yields of any single crop often decrease.
These crops can produce as much as 5 to 20 times the calories per unit of area per unit of time. In biointensive farming, 30% of the land cultivated for food is used for root crops. The use of open pollinated seeds ensures genetic diversity, and allows the farmer to be self-sufficient, harvesting seeds from his or her own plants, and ...
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. It is the sum of the fractions of the intercropped yields divided by the sole-crop yields.
The value and production of individual crops varies substantially from year to year as prices fluctuate on the world and country markets and weather and other factors influence production. This list includes the top 50 most valuable crops and livestock products but does not necessarily include the top 50 most heavily produced crops and ...
Arable land in winter. The headland in the foreground. A Headland, in agriculture, is the area at each end of a planted field. [1] In some areas of the United States, this area is known as the Turnrow. It is used for turning around with farm implements during field operations and is the first area to be harvested to minimize crop damage. The ...
[1] [2] [3] This can be expressed in monetary terms as the monetary yield per unit resource. For example, when applied to crop irrigation it is the yield of crop obtained through use of a given volume of irrigation water, the “crop per drop”, which could also be expressed as monetary return from product per use of unit irrigation water.
