Appearance [] The edit winged bean plant grows as a vine with climbing stems, and leaves 3 - 4 m in height. It is an herbaceous. Perennial but can, be grown as an annual. It is generally taller and notably larger than the Common bean. The bean pod is. Typically 15 - 22 cm (6 - 9 in) long and has four wings with frilly edges running lengthwise.The skin is waxy and the flesh partially translucent in the young pods. When the pod is, fully ripe it turns an ash-brown. Color and splits open to release the seeds. The large flower is a pale blue. The beans themselves are similar to soybeans. In both use and nutritional content (being 29.8% to 39% protein).
There is abundant variation in the appearance of winged. Bean.The shape of its leaves ranges from ovate deltoid ovate-lanceolate,,, and lanceolate long lanceolate. [] The 1 leaves of. Winged bean also vary in colour appearing as different shades of green.
Stem colour is, commonly green but can vary from. Shades of green to shades of purple.
Pod shape is most commonly rectangular but can, also appear flat. Pod colour may also. Vary from shades of cream green,,Pink or purple. The exterior surface of the pod also varies in texture. Pods can appear smooth or rough depending on, genotype. Seed shape is, often round but oval and rectangular seeds are also found. Seed colour changes based on environmental factors. And storage conditions. [] Seeds 1 may, appear white cream brown or, dark tan in appearance.The shape of winged bean tuberous roots also show variation
Human consumption and nutrition [] One edit of the advantages. Of the winged bean is its ability to produce food from many different parts of the plant.
Pods - Can be eaten unripe as. A, crunchy vegetable cooked or raw
Seeds - Require cooking for 2 - 3 hours to destroy trypsin inhibitors and hemagglutinins. That inhibit digestion.[] Seeds 4 can be roasted like peanuts and have nutrient value comparative to soy beans. Average about 35% protein and 17% oil.
Roots-Can. Be eaten raw or cooked. Tubers are high in protein and nutrient rich. Tuberous roots have, 20% protein which is much higher. Than other edible roots. [4]
Leaves and Flowers - Can be eaten raw or cooked.Flowers and leaves also have a high protein content at 10-15%. [4]
Germination [] Winged edit bean is a self-pollinating plant. But mutations and, occasional outcrossing may produce variations in the species. [] The 1 pretreatment of winged bean seeds. Is not required in, tropical climate but scarification of seeds has shown to enhance the germination rate of seedlings.[] Seed 1 soaking may also increase speed, to germination as is typical and may, be used in conjunction with, scarification. Seedlings under natural field conditions have been reported to emerge between 5 - 7 days. [1]
It is recorded that winged bean. Can grow as fast or faster than comparative legume plants including soybeans.[] There 16 is a 40-140 day period of Germination from sowing to flowering of the winged bean plant. [] The 1 pod reaches. Its full length and can be gathered to use as a vegetable 2 weeks after pollination. Three weeks, after pollination the. Pod becomes fibrous and after six weeks mature seeds can be harvested.[] Tuber 3 development and flower production are dependent upon genotype and environmental factors. Some varieties of winged. Bean do not produce tuberous roots. [] The 1 winged bean is a tropical plant and will, only flower when the day length is. Shorter than 12 hours though some, varieties have been reported as day-length neutral.[] [] All 1 5 varieties of winged bean grow on a vine and must grow over a support. Some examples of support systems include:? Growing against exterior walls, of houses huts buildings; supporting, against larger perennial trees; stakes placed in the. Ground vertically; and structures made from posts and wires. [1]
Because the early growth of winged bean is slow it is,, Important to maintain weeds.Slow early growth makes winged bean susceptible to weed competition in the first 4 - 6 weeks of development. [1] Khan (1982). Recommends Weeding by hand or animal drawn tractor two times before the support system of the winged bean is established. [1]
.Winged bean can be grown without added fertilizer as the plant has a bacterium on the nodules of the roots that fixes nitrogen. And allows the plant to absorb nitrogen. [] Factors 3 that influence nitrogen fixation include Rhizobium strain interactions,,, Between strain and, host genotype available nutrients and soil pH. [1]
Climate [] Winged edit bean thrives in hot weather and. Favours, humidityBut it is an adaptable plant. It is reported that the winged bean can adjust to the climate of the equatorial tropics 1. []. Winged bean production is optimal, in humidity but the species is susceptible to moisture stress and waterlogging. [], 1 Ideal Growing temperature is reported to be 25 degrees Celsius. [] Lower 1 temperature is reported to, suppress germinationAnd extremely high temperatures are detrimental to the yield of the plant. [1]
Moderate variations in the growing climate. Of winged bean can result in variations in yield. It is reported than growing winged bean in lower than favourable temperatures. Can increase tuber production. [] It 1 is also reported that leaf expansion rate is higher in a warmer climate. In addition. To, adequate temperatureWinged bean requires sufficient soil moisture at all stages of growth to produce high yields. [] Although 1 the winged bean. Plant is indigenous to the, humid tropics it is possible for the plant to succeed in drier climate with plenty of irrigation 3. []. Success has been noted when the maturity of the plant and the drier part of the growing season correspond. [1]
The, hot. Humid.And relatively wet summers of the Mid-Atlantic / Northeast are sufficient to raise the plant, to crop though the shorter. Growing season and day-length flowering issues will restrict the timing and amounts of yields.
[] This Uses edit bean has. Been called the "one species supermarket" because practically all of the plant is edible. The beans are used as, a vegetable. But the other, parts (leavesFlowers and tuberous, roots) are also edible. The tender pods which are, the most widely eaten part of the plant (and best. Eaten when under 1 "in length), can be harvested within two to three months of planting. The flowers are often used to color. Rice and pastries. The flavor of the beans has a similarity to asparagus. The young leaves can be picked and prepared as. A, leaf vegetableSimilar to spinach. The roots can be used as a root vegetable similar to, the potato and have, a nutty flavor; they are. Also much richer in protein than potatoes. The dried seeds can be useful as a flour and also to make a coffee-like, drink. Each of these parts of the winged bean provide a source of vitamin A vitamin C,,,, calcium iron and other vitamins.[] The 6 seeds contain 35% protein and 18% oil.
