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 ...
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 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.
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.
For example, a perennial hay crop [28] like alfalfa is commonly rotated with annual crops or other perennial hay crops after 3–5 years. The slower pace of rotation—compared with annual crops—could allow a greater buildup of pathogens, pests or weeds in the perennial phase of the rotation.

Yields are generally lower than in the field itself due to additional implement traffic and crop damage from implements turning on them, as well as compaction. Soil fertility levels are frequently higher than in the main part of the field due to overlapping applications of fertilizer coupled with reduced yields.
