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.

Between 1930 and 1942, the United States' share of world soybean production grew from 3% to 47%, and by 1969 it had risen to 76%. By 1973 soybeans were the United States' "number one cash crop, and leading export commodity, ahead of both wheat and corn". [8] Although soybeans developed as the top cash crop, corn also remains as an important ...
A seed rate of about 100 kg of seed per hectare (2 bushels per acre) is typical, though rates vary considerably depending on crop species, soil conditions, and farmer's preference. Excessive rates can cause the crop to lodge, while too thin a rate will result in poor utilisation of the land, competition with weeds and a reduction in the yield .
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 ]
Soybean cyst nematode (SCN) is the worst pest of soybean in the US. Losses of 30% [ 37 ] or 40% [ RM 1 ] are common even without symptoms. The corn earworm moth and bollworm (Helicoverpa zea) is a common and destructive pest of soybean growth in Virginia.
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. Innovations, such as the use of fertilizer , the creation of better farming tools, and new methods of farming and improved crop varieties have improved yields.
