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 improved ...
Grains of rice Rice production in Texas began in 1853 in southeast Texas. By 1903, the acres of cultivated rice in Texas was second only to Louisiana and together accounted for 99 percent of rice production in United States. While other states have surpassed Texas in rice production, it remains a significant Texas crop into the foreseeable future.
In United States federal agricultural law, the terminology Actual Production History (APH) denotes a record of an agricultural producer’s crop yields over a multi-year period. Such records are used by the Federal Crop Insurance Corporation to determine “normal” production levels for a producer.
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.
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
Texas is a leader in cereal crop production. Three counties in the state—Colorado, Wharton and Matagorda—take advantage of water from the Lower Colorado River Authority to grow rice and are responsible for about 5% of annual U.S. rice production. [31] Texas is also a large producer of cantaloupes. [30]
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.
It is also used to describe average yields. Normal production would be the normal crop acreage planted multiplied by the normal yield. These measures, once required by commodity programs to calculate benefits, are replaced by base acres, payment acres, and payment yield under the 2002 farm bill (P.L. 101-171, Sec. 1101-1102).
