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 has the right to represent Welsh farmers in UK government consultations. National Farmers' Union of England and Wales. The National Farmers Union (NFU) was begun by a group of nine Lincolnshire farmers and, as the "Lincolnshire Farmers Union", held its first meeting in 1904. By 1908 they were called the National Farmers Union and were ...
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.
This is a list of countries by vegetable production in 2020 based on the Food and Agriculture Organization Corporate Statistical Database. The total world vegetable production for 2020 was 1,148,446,252 metric tonnes. In 1961 production was 198 mln. tonnes.
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.
Yield mapping or yield monitoring is a technique in agriculture of using GPS data to analyze variables such as crop yield and moisture content in a given field. It was developed in the 1990s and uses a combination of GPS technology and physical sensors, such as speedometers , to track crop yields, grain elevator speed, and combine speed.
The following table shows the vegetable oil yields of common energy crops associated with biodiesel production. Included is growing zone data, relevant to farmers and agricultural scientists. This is unrelated to ethanol production, which relies on starch, sugar and cellulose content instead of oil yields.
Yields have had the seed used to plant the crop subtracted to give net yields. Average seed sown is estimated at: Wheat 2.5 bu/acre; Rye 2.5 bu/acre; Barley 3.5–4.30 bu/acre; Oats 2.5–4.0 bu/acre; Peas & beans 2.50–3.0 bu/acre. $ Average annual growth rate of agricultural output is per agricultural worker.
