The units by which the yield of a crop is usually measured today are kilograms per hectare or bushels per acre. Long-term cereal yields in the United Kingdom were some 500 kg/ha in medieval times, jumping to 2000 kg/ha in the Industrial Revolution, and jumping again to 8000 kg/ha in the Green Revolution. [1]
The US is the world's largest producer of corn. [8] According to the United States Department of Agriculture (USDA), the average U.S. yield for corn was 177 bushels per acre, up 3.3 percent over 2020 and a record high, with 16 states posting state records in output, and Iowa reporting a record of 205 bushels of corn per acre.
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.
Yet corn futures prices are signaling they should hold the grain for a few months, if possible. On the Chicago Board of Trade, benchmark December corn futures were trading at a roughly 22-cent ...
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.
Baby corn ears are hand-picked as soon as the corn silks emerge from the ear tips, or a few days after. Corn generally matures very quickly, so the harvest of baby corn must be timed carefully to avoid ending up with more mature corn ears. Baby corn ears are typically 4.5–10 cm (1 + 3 ⁄ 4 –4 in) in length and 0.7 to 1.7 cm (1 ⁄ 4 – 3 ...
Where: Y is the yield (volume, height, DBH, etc.) at times 1 and 2 and T 1 represents the year starting the growth period, and T 2 is the end year. Example: Say that the growth period is from age 5 to age 10, and the yield (height of the tree), is 14 feet at the beginning of the period and 34 feet at the end.
