The average period for the cowpea plant to mature is between 100-125 days. At this time the leaves will dry down but may not drop off completely. You can leave the pods in the field to enable the seed moisture to reduce.
What is the best time for planting cowpea?
August was recommended for planting cowpea in Ilorin and its environs for optimum seed yield with high quality, but with continuous monitoring of rainfall patterns. Average seed yields of all cowpea varieties planted on four different dates, and associated total rainfall received, 2008.
How long does it take for peas to grow to harvest?
Most pea varieties are ready to harvest 60 to 70 days after planting.
How tall do cowpeas grow?
Height:8-24 inches (bush varieties), 6 feet (vining types)VignaSpread:10-18 inchesunguiculataTolerance:Heat, low fertility soil, drought.var. unguiculataPests & Diseases:Aphids, bean beetles, leafhoppers, root-knot nematodes; bean mosaic virus, Fusarium wilt, powdery mildew.How many days does cowpea take to germinate?
Cowpea Seeds can be sown 0.5 to 1 cm deep. Water the sown seed bed immediately by a light shower using a watering can. Seeds will germinate within the first 6-8 days & tiny sprouts will be visible.
How do you increase cowpea yield?
Research results show that proper management of organic amendments such as crop residues and manure, which are essential complements to mineral phosphorus fertilizers, can increase yields of cowpea and associated cereals more than three fold.
Which fertilizer is best for cowpea?
Cowpea does not require too much nitrogen fertilizer because it fixes its own nitrogen from the air using the nodules in its roots. However, in areas where soils are poor in nitrogen, there is a need to apply a small quantity of about 15 kg of nitrogen as a starter dose for a good crop.
How deep do you plant cowpeas?
Spacing Requirements: Plant the cowpea seeds 2-3 inches apart, ½ inch deep directly into warm soil. Time to Germination: Cowpeas are quick to germinate.Do cowpeas fix nitrogen?
Other grain legumes, such as peanuts, cowpeas, soybeans, and fava beans, are good nitrogen fixers and will fix all of their nitrogen needs other than that absorbed from the soil. These legumes may fix up to 250 lb of nitrogen per acre and are not usually fertilized (Walley et al., 1996; Cash et al., 1981).
Can cowpeas grow in shade?Cowpeas tolerate shade, and can be planted near taller crops. They are also drought resistant. … Cowpeas’ roots also access phosphorus that may be limited in the soil. And, their quick growth and rapid ground cover prevent soil erosion.
Article first time published onDo cowpeas need trellis?
Vining varieties are very vigorous and drought resistant, but they should be given extra room, or trellised, or planted so they can climb stalks of dent corn.
Can you transplant cowpeas?
You can plant directly outdoors, as soon as the danger of frost has passed. Water your seeds before planting them to speed up their germination, and keep in mind that, while you can start your cowpea seeds inside and then transplant the seedlings, there’s really no reason that you have to do this.
Do pea plants reproduce quickly?
Peas usually reproduce by self-pollination, in which pollen produced by a flower fertilizes eggs in the same flower. Pea plants grow quickly and do not require much space.
Why are my peas not growing?
Any number of poor growing conditions can also attribute to garden peas not producing. Cold, wet springs or hot, dry weather can impede the development of root nodules and inhibit nitrogen fixing. Planting peas too late in the season can cause the plants to turn yellow and die before setting pods.
How many peas will one plant produce?
Pea plants usually produce 5 or 6 peas in each pod. Suppose a pea plant had 5 pods and a total of 26 peas.
Are cowpeas Bush or pole?
Say that 10 times fast…if you can. This spring/summer we grew them out to see how they would do in our climate. Cowpeas, you should know, are available as both bush and pole varieties.
What are the growth stages of cowpea?
Cowpea can be harvested at three different stages of maturity: green snaps, green-mature, and dry.
What can I plant with cowpeas?
Cowpeas can also be mixed with other crops to help protect them from early overgrazing. Combinations can include mixing with other summer annuals, like grain sorghum and/or buckwheat, or cool-season forage grasses depending on what time of the year you plant.
What is the nitrogen requirement in cowpea?
Manuring. Apply FYM/compost – 5 – 10 t/ha as basal with last ploughing. 15 – 20 kg N/ ha as starter dose in poor soils (organic carbon<0.5%), 50 – 60 kg/ha P2O5 and 50 – 60 kg.
What is the propagation of cowpea?
Cowpea is propagated through seeds, this increases the waiting period as the plant has to complete its juvenile phase before flowering. … The vine cuttings were planted in sterilized top soil and they began flowering 14 days after cutting without adding fertilizer.
How do you measure the height of a cowpea plant?
Plant height (m) was measured from the main stem, from ground level to the tip of the plant using a meter ruler. Reproductive parameters were collected after harvesting the two middle rows from each experimental unit.
In what way is NASA on the cowpea bandwagon?
Even the National Aeronautics and Space Administration (NASA) is on the cowpea bandwagon. With the plant’s ability to produce nutritious leaves in only about 20 days, NASA scientists are considering sending cowpeas to the international space station, where they could be cultivated to provide food for astronauts.
What are the two steps of nitrification?
Nitrification is mediated by microorganisms including Bacteria and Crenarchaeota and occurs in two steps. In the first step, ammonia is oxidized to nitrite and in the second step nitrite is oxidized to nitrate.
What is the best cover crop for nitrogen?

Which legume produces the most nitrogen?
Grain legumes such as soybean and peanut use most of their fixed nitrogen for themselves. Forage legumes, such as alfalfa and clovers, are the best crops for companion planting as they can fix substantial amounts of surplus nitrogen under the right conditions.
Should I soak cowpeas before planting?
Most of them have hard coats, and all benefit from soaking before planting. Soak them overnight in warm water. This will expedite the germination process. Each pea variety is in its own plastic container filled half full with water, so the peas are well covered.
Do I need to soak cowpeas before planting?
It is a good idea to soak pea seeds before planting. Soaking them for a day prior to planting helps them germinate, though it is not strictly necessary.
Are cowpeas good for soil?
Cowpeas protect soil from erosion, smother weeds and produce 100 to 150 lb. N/A. Dense residue helps to improve soil texture but breaks down quickly in hot weather.
Will cowpeas grow in clay soil?
Like many legume species, cowpeas (southern peas) have vigorous, dense, fibrous roots that break up clay soil. As nitrogen fixers, they enrich and enliven the soil. Sow in the spring as a summer cover crop. They grow quickly to suppress weeds, and the flowers attract beneficial insects.
Can cowpea grow in winter?
The cowpea plant won’t tolerate frost or cold temperatures and will die off in the winter.
Are cowpeas perennial?
Cowpeas are perennial in USDA Zones 7 – 10, but are often grown in the midwest as an annual in USDA Zone 5 and 6.
