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.
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). [ 3 ] It is also possible to calculate LERs for combinations of plant and non-plant yields, e.g. in agrivoltaic systems.
Wheat yields in least developed countries since 1961. The steep rise in crop yields in the U.S. began in the 1940s. The percentage of growth was fastest in the early rapid growth stage. In developing countries maize yields are still rapidly rising. [6] Productivity is driven by changes in either agricultural technique or improvements in technology.
The combine grain yield monitor is a device coupled with other sensors to calculate and record the crop yield or grain yield as a modern-day combine harvester operates. Yield monitors are a part of the precision agriculture products available to producers today that provide producers with the tools to reduce costs, increase yields, and increase efficiency.
The yield of grapes that will be harvested from a vineyard will depend on several factors including vintage conditions, local wine laws and winemaker's preference. In viticulture, the yield is a measure of the amount of grapes or wine that is produced per unit surface of vineyard, and is therefore a type of crop yield. Two different types of ...
Direct payment yields for wheat, feed grains, cotton, and rice on a farm are the 2002 PFC payment yields for the applicable crops on the farm. Yields used to calculate direct payments cannot be updated; the yields must be those used for PFC.
Stress factors can affect growth, survival and crop yields. Plant stress research looks at the response of plants to limitations and excesses of the main abiotic factors (light, temperature, water and nutrients), and of other stress factors that are important in particular situations (e.g. pests, pathogens, or pollutants). Plant stress ...
In climate engineering, the residue-to-product ratio (RPR) is used to calculate how much unused crop residue might be left after harvesting a particular crop. Also called the residue yield or straw/grain ratio, the equation takes the mass of residue divided by the mass of crop produced, and the result is dimensionless.
