Sunflower production in the Iringa District

Abstract

The sunflower (Helianthus annuus), which is a summer annual, can be successfully grown in all areas where maize is produced. It is distinctly drought resistant and will give good yields on soils too poor and in seasons too dry, wet or cold for good yields of maize. In lringa District it crops on all types of soils from heavy clays to almost pure sands. Its altitudinal range varies from 7,000 ft. under forest conditions, to 3,000 ft. in arid thorn country.
