Cowpea growth introduction
Cowpea prefers sunlight, but also more shade-tolerant, the soil should not be too wet, so as not to cause rotting seeds, requires suitable air humidity and soil moisture, more distributed in the temperate zone, the tropics and subtropics, the main producing areas in Liaoning, Henan, Hunan, Guangxi, Sichuan, Taiwan and other provinces and regions.
Cowpea Growth Cycle
Cowpea seedlings have to build shelves when they reach 30 centimeters because its top branches have a twining climbing habit and will climb upward by themselves. The cowpea growing period is usually divided into two, in the spring it takes about 120 days to grow and in the fall it takes about 100 days.
Cowpea growth rate
The cowpea seedling stage takes 15 to 20 days, and the vining stage usually takes about 10 to 15 days, when the main vines elongate rapidly and rhizomes begin to form. The flowering and podding period is generally 50 to 60 days from the time the plant buds appear to the end of pod harvesting.
Management of cowpea growth cycle
Cowpea yields around 3,000 kilograms per mu, it has more varieties and yields can vary, for example, E cowpea 12 yields around 1,700 kilograms per mu, Gui cowpea 1, Cheng cowpea 10, etc. yields about 2,000 kilograms per mu, and Early cowpea 4 yields about 3,000 kilograms per mu.
Temperature management: Cowpea is best grown in 20-25 degrees Celsius, and can withstand high temperatures above 35 degrees Celsius in summer. However, it does not tolerate frost, and growth is inhibited by longer periods of low temperatures below 10 degrees Celsius.
Fertilizer management: Cowpea should ensure the supply of fertilizer elements, fertilizer should be applied in conjunction with nitrogen, phosphorus, potassium, supplemental boron fertilizer, molybdenum fertilizer, in order to promote the pods, and increase the yield.
