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.
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.
Countries by soybean production in 2020. This is a list of countries by soybean production from 2016 to 2022, based on data from the Food and Agriculture Organization Corporate Statistical Database. [1] The total world production for soybeans in 2022 was 348,856,427 metric tonnes, down 6.4% from 372,853,699 tonnes in 2021. [1]
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.
A high plant population does not necessarily equal a high yield. The recommended seeding rate is 125,000 to 140,000 seeds per acre. [2] The goal is to achieve a final stand of 100,000 plants per acre. [2] Planting the extra seed gives the producer added insurance that each acre will attain a final stand of 100,000 plants.
For example, the U.A.D.A. recommends 150 lb. N/acre ("this recommendation is for N applied in a 2 or 3-way split application where 90 lb N/acre is applied preflood and followed by 60 lb N/acre at midseason") for Wells rice grown in rotation with soybeans on silt/sandy-loam soils.
Soybeans are consumed by whitetail deer which may damage soybean plants through feeding, trampling and bedding, reducing crop yields by as much as 15%. [39] Groundhogs are also a common pest in soybean fields, living in burrows underground and feeding nearby. One den of groundhogs can consume a tenth to a quarter of an acre of soybeans. [40]
The fastest growing import markets in soybeans for Paraguay between 2019 and 2020 were Brazil ($685k)and Argentina ($489k). [5] The United States soy trade has had little influence on South America’s production because the U.S. grows enough to meet its own demand. Nonetheless, the demand from Asia has been vast enough to spur a 69% increase ...
