An annual summer forage legume with a spreading growth habit that is tolerant of both drought and heat. Buff cowpeas can be used to fatten cattle and sheep, or as a green manure crop to improve soil nitrogen levels, and they produce quality hay or silage especially in a mix with forage sorghums or millet. They grow in a variety of soils but do not like being waterlogged.
Key attributes
- Good drought and heat tolerance
- Excellent source of nitrogen in summer rotations
- Good companion legume with millet and sorghum
- Adds protein to silage and hay
- Excellent green manure crop
- Does not tolerate waterlogging
About this variety
Buff is a cowpea, an annual summer forage legume with a spreading growth habit, and it is one of the more useful legumes for the warm season.
Cowpeas tolerate both drought and heat, which is what suits them to summer country where a temperate legume would fail, and they can be used in several ways: fattening cattle and sheep, as a green manure to lift soil nitrogen, or cut for hay and silage, particularly in a mix with forage sorghum or millet where the legume lifts the protein of a grass-dominant crop.
That companion role is where cowpeas are most often used. A summer grass crop grown alone is bulky but low in protein; a cowpea component raises the quality of both the standing feed and the conserved product.
They grow on a variety of soils but will not tolerate waterlogging, so drainage matters more than fertility.
Seed should be inoculated with group I inoculant before sowing to ensure nodulation and nitrogen fixation, without which most of the benefit is lost.
Planting & grazing notes
Sow when soil temp reaches 16°C, needs 25-35°C to grow and good soil moisture; inoculate with Group I; row spacing 18-35cm for 9-13 plants/m²; light grazing recommended for regrowth; responds well to P, K, S fertiliser. Cowpeas were released to Australia as a grazing type of cowpea suited to subtropical coastal areas with medium rainfall or in areas with irrigation but does not like to be waterlogged.
Disease & pest resistance
Susceptible to Phaseolus and root rot fungus; susceptible to frost
