Pigeon Pea

Pigeon pea is a tropical legume cultivated for edible pulse seed and valued in mixed farming systems. It can also provide fodder, cover, windbreak and soil-improvement benefits.

Cajanus cajan (L.) Millsp. · Perennial-capable tropical grain legume commonly grown as an annual

Profile

Crop
Pigeon pea is an upright legume that is commonly managed as an annual.
Food
Seeds are consumed fresh, dried or as flour.
Farm role
It can be used in intercropping and crop rotations.
Pests and diseases
Pigeonpea guidance identifies pod borers, pod fly, pod-sucking bugs, blister beetles, bruchids and Fusarium wilt as management concerns.

Water & soil context

Moisture (VWC)
Use well-drained soil and supply water based on local rainfall and crop stage; avoid waterlogged conditions.
Salinity tolerance
Salt sensitivity is not documented in the cited pages.
Drought tolerance
A drought classification is not documented in the cited publications.

Illustrative monitoring-depth band

3–8 in

Editorial placement example, not a validated optimum or total rooting depth. Confirm the site's root distribution and soil horizons; multiple depths may be needed.

The sources provide crop-management guidance but do not establish a numeric root-zone moisture target; locally adjust irrigation to soil and weather.

Problems to watch

  • Inspect pods for borer or fly injury and check for sucking bugs; monitor for Fusarium wilt.

Stress signs

  • Fusarium wilt is a named disease concern; use local diagnostic support to distinguish wilt from water stress.

Where you'll find it

  • Fresh, dried and flour-form pulse food
  • Livestock fodder
  • Intercropping, windbreak and cover crop
