Growth period: 100–150 days.
Temperature: very frost tolerant. Semi-dwarf types are adapted to temperate
climates.
resistant.
Pests and diseases: rarely a problem; locusts, grasshoppers and armyworms
sometimes attack.
YIELD
When intercropped with finger millet in India Niger seed yields about 100–200
kg/ha. Pure stand yields have been recorded in both India and Ethiopia of about
300–400 kg/ha, 400–600 kg/ha in Kenya. 1.2 MT/ha is possible with good growing
conditions.
Oil yields are 30–50% of dried seed yield.
UTILISATION
- drying oil which is yellow in colour and tastes of nuts. Seeds can also be used
fried or as chutneys and condiments, or fed to caged birds. In Ethiopia they are
making paints. It is used as a substitute for olive oil, can be mixed with linseed
oil, and is commonly used as a (less expensive) adulterant for rape oil, sesame
cattle. This black oilcake is comparable in feeding value to undecorticated
groundnut cake. Up to 30% can be added to laying poultry rations. It is
sometimes used as manure and/or soil improver.
LIMITATIONS
extract oil from Niger seed than from other oilseed crops.
Rainfall: about 600–1800 mm a year for all types. Dwarf types are more drought
Altitude: the optimum is around 2000–2200 m, but it can be cultivated from about
1600–2600 m.
