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 ...
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.
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 Pro Farmer Crop Tour found ideal growing conditions could supercharge Iowa's corn yield
The middle plot was originally planted in a rotation of corn and oats, with the oats replaced by soybeans in 1968. The southern plot was originally planted in a rotation of two years of corn, one year of oats, and three years clover; this was replaced in 1901 by a rotation of corn, oats, and clover, and in 1953 by corn, oats, and alfalfa.

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.
