The crop is day –length sensitive, flowering into shortening days. Planting in spring will yield a large quantity of fodder at the expense of pods and grain, while sowing with normal summer planting rains optimizes grain production. Late summer plantings are generally not successful, since reproductive growth commences while plants are still in the seeding stage. Increased fertility increases vegetative growth at the expense of grain production.
Inoculation of seed is not necessary. The plant density should be between 100 000 and 150 000 plants per hectare. The variety IT 18 was selected from IITA material and is widely used in Southern Africa. It is a semi-bush type, mainly to grain production. Grain is light brown in colour. IT 18 has about 8 000 seeds/kg.
