Cowpea (Vigna unguiculata)

Weed management

  • Application of post emergence herbicide Imazethapyr + Imazamox @40 g/ha or Imazethapyr @40 g/ha at 3-4 leaf stage of weeds can control grasses, sedges and broad leaved weeds.

Intercultural practices

  • Hoeing at the time of application of the second dose of nitrogen will give adequate aeration to the soil and help the root system to spread easily.
  • For grain and dual-purpose varieties, decapitation is found to be advantageous as the crop shows trailing tendency.
  • Irrigating on the 15th day after sowing and during flowering will increase yield.
  • For vegetable types, provide trellis or pandal for trailing.
