Poor stand establishment and slow rate of growth were the major agronomic deficiencies. Biomass yield was low. Anthesis did not occur prior to frost. Niger Guizotia abyssinica Cass. The crop is grown for its high quality oil which is extracted from the seed.
Niger oil is used for human consumption and in the manufacture of soap and paints.
The five lines tested were all late maturing and seed set was low. Early maturing lines need to be developed in order for this crop to be productive in North Dakota. Poor stand establishment and low seed set occurred at all locations and planting dates. Beerentrup, H.M. Zu, and G. Robbelen. Screening for European productions of oilseed with unusual fatty acids.
