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. Cereal yield in tons per hectare and kilograms of nitrogenous fertilizer applied per hectare of cropland.
Sweet potatoes have been a part of the diet in the U.S. for most of its history, especially in the Southeast. The average per capita consumption of sweet potatoes in the United States is only about 1.5–2 kg (3.3–4.4 lb) per year, down from 13 kg (29 lb) in 1920.
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.
A sweet potato casserole recipe might call for three pounds, or about 48 ounces, of sweet potatoes. By Burgess’s estimation, that should equate to 9 to 12 servings. By Burgess’s estimation ...
The sweet potato (Ipomoea batatas) is a very important crop for subsistence farmers in Africa and developing countries in other regions. [1] [2] Its relatively short growing period, tolerance to drought and high yield from poor soils lead to its use as a famine reserve for many of these households.
Planning an effective rotation requires weighing fixed and fluctuating production circumstances: market, farm size, labor supply, climate, soil type, growing practices, etc. [16] Moreover, a crop rotation must consider in what condition one crop will leave the soil for the succeeding crop and how one crop can be seeded with another crop. [16]
Biocapacity is expressed in terms of global hectares per person, thus is dependent on human population. A global hectare is an adjusted unit that represents the average biological productivity of all productive hectares on Earth in a given year (because not all hectares produce the same amount of ecosystem services ).
The United States was the most productive country, with a nationwide average yield of 44.3 tonnes per hectare (19.8 short tons per acre). [79] New Zealand farmers have demonstrated some of the best commercial yields in the world, ranging between 60 and 80 tonnes per hectare, some reporting yields of 88 tonnes of potatoes per hectare.
