Planting Cowpeas

Planting Cowpeas

Cowpeas are the oldest annual leguminous plant cultivated throughout India for green pods, dry seeds, green manure, and forage. It is considered a culture of African origin. Drought tolerant crop, fast-growing, weed control early. It also helps to retain soil and moisture. Korovin is a good source of protein, calcium, and iron. It is grown in the irrigated areas of Punjab.


Temperature 22-35°C
Sowing Temperature 22-28°C
Harvesting Temperature 30-35°C
Rainfall 750-1100mm


It can be grown in a variety of soils but produces the best results when grown in well-drained loamy soils.


  • Cowpea 88: Recommended for statewide cultivation. It is grown for both feed and grain. Its pods are large, and the seeds are fatty, have a chocolate brown seed color. Resistant to yellow mosaic and anthracnose. This gives an average seed yield of 4.4 liters/acre and 100 quarts/acre of green forage.
  • CL 367: It can be grown for both feed and grain. It is carried by a large number of pods. Seeds are small, creamy white. Provides resistance to yellow mosaic virus and anthracnose. This gives an average seed yield of 4.9 qt/acre and 108 qt/acre of green fodder.
  • Kashi Kanchan: A dwarf and shrub variety suitable for both summer and rainy seasons. The beans are soft, dark green in color. This gives an average pod yield of 60-70 quarts/acre.
  • Pusa Komal: gives an average yield of 40 quarts/acre.
  • Kashi Unnati: The pods are soft and light green in color. The first cuttings are ready for harvesting 40-45 days after sowing. Gives an average yield of 50-60 quarts/acre.


Like other legumes, the usual preparation of the bed was required. Plow twice to turn the soil into shallow plowing and cover after each plowing.


  1. Sowing time. The best time for sowing is from March to mid-July.
  2. Row spacing. when sowing, use a row spacing of 30 cm and a plant spacing of 15 cm.
  3. Depth. sowing The sowing depth should be 3-4 cm.
  4. Sowing method. Sow seeds with a fertilizer planter or seeder.


Seeding rate
When sowing for feed, use a seeding rate of 20-25 kg for the Cowpea 88 variety and a rate of sowing 12 kg for variety CL 367.

Seed treatment
Before sowing, spray Emisan 6 seed @ 2.5 g / kg seed. or carbendazim 50% WP @ 2 g / kg seed. It will protect the seeds from rot and seedling death.


Fertilizer Requirement (kg/acre)

17 140 Apply if deficiency observed


Nutrient Requirement (kg/acre)

7.5 22

At the time of planting, inject N @ 7.5 kg as urea @ 17 kg / acre along with P @ 22 kg as single superphosphate @ 140 kg / acre. Korovina reacts well to phosphorus fertilizers. It helps to improve roots as well as plant growth, plant absorption of nutrients, nodules, etc.


To protect crops from weeds, apply 750 ml/acre of pendimethalin per 200 liters of water within 24 hours of planting.


For good growth, an average of 4-5 waterings is required. When sowing a crop in May, water at intervals of 15 days before the arrival of the rainy season.


  • Pests and control of them:

Jasid and black aphid: If infestation with yassid and black aphid occurs, spray Malathion 50EC at 200 ml / acre per 80-100 liters of water.

  • Bihar Hairy Caterpillar: Infestation is high from August to November. To protect your crop from this pest, during sowing, take one row of sesame seeds around the cowpea field.
  • Diseases and their control:

Sowing rot and seed death: caused by different microflora transmitted through the seeds. Infected seeds shrivel and change color. Infected seedlings die before they emerge from the soil and cause poor crop growth. To control sowing, treat seed with Emisan 6 @ 2.5 g / kg seed or Bavistin 50WP @ 2 g / kg seed before sowing.


After 55-65 days, the crop is ready for harvest.
