Vegetable Cowpea (Vigna unguiculata (L) Walp.)
Co 2, VBN 2, Pusa Komal, PKM 1 and Arka Garima are commonly cultivated.
Well drained soil with rich organic matter content and warm humid climate is best suited for the cultivation of vegetable cowpea.
June – July (Rainfed), February – March (irrigated)
20 kg of seeds/ha is required.
Treat the seeds with Rhizobium bacterial culture 600 g before sowing.
Preparation of field
Plough the field to fine tilth and form ridges and furrows at 45 cm apart or beds of convenient sizes.
Dibble the seeds on both sides of the ridges or in lines in the beds at 45 x 15 cm spacing.
Give irrigation immediately after sowing and on 3rd day, thereafter once a week.
Application of fertilizers
Apply FYM 25 t/ha, Azospirillum and Phosphobacteria 2 kg /ha and N 25 kg and P 50 kg/ha for irrigated crop. Apply FYM at 12.5 t/ha and N 12.5 and P 25 kg/ha for rainfed crop.Fertilizers can be applied in several split doses at fortnightly intervals.
Before flowering, the tendrils should be pinched thrice for getting bushy plants.
Give one hoeing and weeding on 25th day after sowing.
Aphids can be controlled by spraying Dimethoate 30 EC 1 ml/lit or Methyl demeton 25 EC 1 ml/lit.
Pod borer can be controlled by spraying Quinalphos 25 EC 2ml/lit.
Powdery mildew can be controlled by dusting Sulphur 25 kg/ha or spray Wettable sulphur 2 g/lit.
2500 kg (rainfed) and 5000 kg (irrigated) in a crop duration of 75 to 90 days can be obtained.
