Find out who eats what--and why. The soybean is an erect branching plant and can reach more than 2 metres (6.5 feet) in height. The self-fertilizing flowers are white or a shade of purple. Seeds can be yellow, green, brown, black, or bicoloured, though most commercial varieties have brown or tan seeds, with one to four seeds per pod.

How much space do you need to grow soybeans?

Soybean plants at maturation are quite large, 2 feet (61 cm.) tall, so when planting soybeans, be aware that they are not a crop to attempt in a small garden space. Make rows 2 to 2 ½ feet (61-76 cm.) apart in the garden with 2 to 3 inches (5-8 cm.) between plants when planting soybeans.

What is the physiological maturity of soybean seed?

The soybean seed at physiological maturity is about 60 percent moisture and contains all necessary plant parts to begin the next generation soybean plant. As pods and seeds mature, they become less prone to abort. As a result, the total number of pods per plant and number of beans per pod gradually become set with plant maturity.

These first flowers generally appear at the base of a raceme . With time the raceme elongates while new flowers appear progressively toward the raceme tip. By the R5 stage, the plant has completed most of its flowering but a few newly opened flowers may be present on branches and upper main stem nodes. Almost all soybean flowers pollinate them selves at, or a little before, the time of flower opening.

What does the color of soybean pods mean?

The sequence of color and size changes the soybean pod and beans undergo from green R6 beans to the mature beans ready for harvest. Mature pod color does not always indicate harvestable readiness of the beans within. With favorable drying weather, soybeans will lose moisture quickly.

What do axillary buds do to soybeans?

The axillary buds of the unifoliolate and trifoliolate leaves and of the cotyledons, allow a tremendous capacity for the soybean plant to recuperate from damage such as hail. The stem apex, or tip growing point, normally exhibits dominance over the axillary buds (axillary growing points) during vegetative growth of the plant. If the stem apex is severed or broken off along with part of the stem, however, the remaining axillary buds are released from this dominance and branches grow profusely. The plant, therefore, has the ability to produce new branches and leaves after hail destroys almost all of the above ground foliage. Severing the plant below the cotyledonary node kills it because there are no axillary buds below this node.

How does soybean seed germination begin?

The planted soybean seed begins germination by absorbing water in amounts equal to about 50 percent of its weight. The radical or primary root is first to grow from the swollen seed where it elongates downward and anchors itself in the soil. Shortly after initial primary root growth, the hypocotyl (small section of the stem between the cotyledonary node and the primary root), begins elongation toward the soil surface pulling the cotyledons (seed leaves) with it. The anchored primary root and elongating hypocotyl provide leverage for pulling the cotyledons to the soil surface for VE or emergence. VE typically occurs 1 to 2 weeks after planting, depending on soil moisture, soil temperature, and planting depth. Lateral roots begin to grow from the primary root just prior to emergence.

How long does it take for a soybean to flower?

Almost all soybean flowers pollinate them selves at, or a little before, the time of flower opening. Three to 4 days after an individual flower opens, the flower petals are dried out and the pod (fruit) begins to elongate. By 2 to 2 1/2 weeks after this individual flower opens, a full length pod has formed.

How many stages are there in soybeans?

The R stages are subdivided into eight stages. Vegetative and reproductive stages of a soybean plant. The V3 stage is defined when the leaflets on the 1st (unifoliolate) through the 4th node leaf are unrolled. Similarly, the VC stage occurs when the unifoliolate leaves have unrolled.

How long does it take for soybeans to flower?

Flowering is triggered by day length, often beginning once days become shorter than 12.8 hours. This trait is highly variable however, with different varieties reacting differently to changing day length. Soybeans form inconspicuous, self-fertile flowers which are borne in the axil of the leaf and are white, pink or purple. Depending of the soybean variety, node growth may cease once flowering begins. Strains that continue nodal development after flowering are termed " indeterminates " and are best suited to climates with longer growing seasons. Often soybeans drop their leaves before the seeds are fully mature.

What are the soluble carbohydrates in soybeans?

The principal soluble carbohydrates of mature soybeans are the disaccharide sucrose (range 2.5–8.2%), the tri saccharide raffinose (0.1–1.0%) composed of one sucrose molecule connected to one molecule of galactose, and the tetrasaccharide stachyose (1.4 to 4.1%) composed of one sucrose connected to two molecules of galactose. While the oligosaccharides raffinose and stachyose protect the viability of the soybean seed from desiccation (see above section on physical characteristics) they are not digestible sugars, so contribute to flatulence and abdominal discomfort in humans and other monogastric animals, comparable to the disaccharide trehalose. Undigested oligosaccharides are broken down in the intestine by native microbes, producing gases such as carbon dioxide, hydrogen, and methane .
