Yellow or green soy plant: botanical info, photos, images of the flower, information on the cultivation and properties of soy.
With the term "soy" we identify iseedsof theplantGlycine max. Theresoy plantit is native to Asia and widely cultivated for its multiple food uses. Soy is grown for both human and animal nutrition. For the properties and all the soy-based products that we find on the market, I invite you to read the page "Soy, all the information ".
Soybean cultivation is widely used for the production of oil (soybean oil), vegetable milk (soy milk), vegetable meat (tempeh), soy sauce, fermented products, vegetable cheeses (tofu), bean sprouts, feed animals and much more.
Do you think the main soy producing country is Asian? No, in the world, the main soybean producers are the United States (covering 32% of global production), followed by Brazil (which covers 31% of global production) and finally Argentina (with 18%).
The optimal conditions for the growth and development ofsoy plantsthey see a climate with mild temperatures, between 20 and 30 °. Temperatures below 20 ° C significantly slow down growth.
Yellow soy plant
In fact, there are two species of soy, Glycine max (cultivated soy) and Glycine soja (wild soy). Both species see an annual cycle.
Botanists describe wild soy (Glycine soja) as the ancestor of Glycine max. Therewild soyit grows spontaneously in China, Japan, Korea and in the easternmost part of Russia. Farmers today have selected different varieties of soybeans starting from the Glycine max species.
In the photo above you can see the seeds of different variety of soybeans.
Green soy is not a variety obtained from botanical crosses. Green soy is a separate botanical species that we will analyze later because, although it shares uses and cultivation methods, it has nothing to do with yellow soy.
Some are shown in the photo belowsoybean flowers. THEsoybean flowersthey are not flashy. Typically, the flowers are axillary. The soy flower is self-fertile and, depending on the variety, can be pink, purple (as in the photo) or white.
Just like with tomatoes, we also have varieties with determined growth and varieties with indeterminate growth with soy. Thesoy plantswhich stop growing following flowering are calledplantswith determined growth. When soybean plants continue to develop nodes, even after flowering, they are termed indeterminate growth.
Thesoy plants, generally, they lose their leaves before the seeds are fully ripe. Thefruitit is a pod 3 to 8 cm long and usually contains two to four seeds. THE soya beans (i.e. those that we call legumes and that we ingest) can have a diameter from 5 to 11 mm. According to the variety we can haveblack soy, brown soy, the classic yellow soy and the most unusualblue soy.
Soy is a legume
Like all legumes, even thesoy plantsthey have the ability to fix nitrogen from its atmospheric gaseous form. This ability derives from symbiotic bacteria that find their habitat in the nodules of roots of the soybean plant.
Green soybean or mung bean plant
As stated, yellow soy is a legume produced by plant Glycina maxwhile the green soy it is obtained from plants of the botanical species Vigna radiata, better known asmung bean. For all information on thegreen soy(cultivation, nutritional information, uses in cooking…) I invite you to read the page: green soy or mung bean.
