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.
In 2015, therefore, approximately 4.55 kg of farmed fish was produced for every 1 kg of wild fish harvested and used in feed. (For Salmon & Trout, the FIFO ratios for 2000, 2010, and 2015 are: 2.57, 1.38, 0.82.) [30] As of 2015 farm-raised Atlantic salmon had a commodified feed supply with four main suppliers, and an FCR of around 1. [31]
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.

In the same year, there were 13.7 million harvested acres of corn for grain, producing 2.36 billion bushels, which yielded 172.0 bu/acre, with US$14.5 billion of corn value of production. [29] Almost 1.88 billion bushels of corn were grown in the state in 2012 on 13.7 million acres of land, while the 2013 projections are 2.45 billion bushels of ...
Beginning stocks represent the previous year’s ending or carry-over inventories. Total production represents the total grain produced in a given year. Total usage is the sum of all the end uses in which the stock of grain has been consumed. This would include human consumption, export programs, seed, waste, dockage and feed consumption ...
The maximum sustainable yield is usually higher than the optimum sustainable yield and maximum economic yield. MSY is extensively used for fisheries management. Unlike the logistic model, [1] MSY has been refined in most modern fisheries models and occurs at around 30% of the unexploited population size.
