By type winged bean plants were divided into 2 types of blue-winged and white-flowered flowering. Winged
species have white flowers over a long fruit that is between 30-40 cm
and a small seed, while the blue-winged flower has only length 15-20 cm,
and large seeds.
II. Technical culture
Winged bean is an annual plant that can grow from lowlands to highlands.
Winged propagated by seed. Way of planting, fertilization, installation lanjaran for winged bean plants similar to those for roay.
Harvesting can be done after the old plant from 3.5 to 4 months. Delay harvest can cause fruit fiber harder and harder to sell.
III. Seed Production
Aquaculture production of seed
for the production of winged bean seed cultivation is almost the same
as consumption, but there are treatments that aim to maintain the
genetic purity of seeds produced, the isolation distance and selection
including self-pollinated plants (self pollinated), but
cross-pollination can occur through insect, so that the required
isolation distance of approximately 50 m. Selection
(roguing) performed on plant vegetative growth phase, the phase of
flowering and fruiting phase, include: uniformity of growth, leaf shape,
flower color, fruit shape, and others.
When harvesting seeds
Winged bean seed harvesting time around 120 days after the seedlings in the highlands, have been characterized in brown pods. Winged bean pods are harvested by plucking.
Seed drying and processing
winged bean pods to be harvested in dry conditions on the tree or dried
in the sun until the seed moisture content reaches about 8.0 - 10.0%. Subsequently removed from the pods and seeds should be packed. The number of seeds in the pods of winged bean variety, ranging from 5-17 seeds.
bean seeds or seeds that have been dried can be packaged in paper, but
it will be even better if you use aluminum foil packaging because it is
possible air in the box with aluminum foil is also sucked out using a
vacuum (vacuum), so the initial seed moisture content can be maintained.
are packed in paper packaging should be stored in glass jars that have
been given desikan materials, such as: silica gel; charcoal; gray pads,
so the air inside the jar is expected to remain dry and can maintain the
initial seed moisture content. For seed packaged in aluminum foil should also be stored in a closed container jars. Furthermore jars stored in a dry and cool. If possible can be stored in a seed warehouse temperature and humidity can be set (t = 18o C; RH = 30%).
