A great cover crop for warmer weather. Grown much like soybeans. Frost sensitive, but fast growing in warm/hot weather. Sow mid spring once soil has warmed. Sow at 1.5kg per 100m2, 1 to 2cm deep. Relatively long taproots help withstand drought. Cowpeas are not tolerant of high weed pressure or wet soils and will perform poorly in these conditions. If planted thickly, they will smother out weeds. Cowpeas can also be used for underseeding in spring crops and tilled under prior to fall-planted crops. They can produce as much as 150 kg / acre nitrogen, though 50kg / acre nitrogen is more typical.
