However, unshelled mean yields of up to 3 tonnes per hectare were reported when cultivating some landraces in the transition agro-ecological zone in Nigeria . A low mean yield of 0.85 tonnes per hectare was reported in Ghana under good management practices close to yield levels of other legumes such as cowpeas (0.80 tonnes per hecatare) and ...
ICRISAT-improved chickpea varieties have been widely adopted in a poor tribal area in Gujarat, India, with favorable impacts on yields, unit production costs, and net returns per hectare/per acre. ICRISAT's package of improved groundnut varieties grown in combination with improved agronomy practices has had a positive result in the semi-arid ...
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 ...
Apios americana, sometimes called the American groundnut, potato bean, hopniss, Indian potato, hodoimo, America-hodoimo, cinnamon vine, or groundnut (not to be confused with other plants in the subfamily Faboideae sometimes known by that name) is a perennial vine that bears edible beans and large edible tubers.
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.
For example, average yields of corn (maize) in the US have increased from around 2.5 tons per hectare (t/ha) (40 bushels per acre) in 1900 to about 9.4 t/ha (150 bushels per acre) in 2001. Similarly, worldwide average wheat yields have increased from less than 1 t/ha in 1900 to more than 2.5 t/ha in 1990.
In a similar experiment to reproduce Native American agricultural practices in Minnesota, Munson-Scullin and Scullin reported that over three years, the per-acre annual maize yields declined from 40 to 30 to 25 bushels (2.5, 1.9, and 1.6 t/ha). [16] Other scholars have estimated lower average yields of maize.
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.
