|Wheat and barley have a high potential in most areas in Zambia. However, medium to heavy fertile soils with good drainage and water-holding capacity should be selected for seed production. This applies to both irrigated and rainfed crops. Irrigated wheat and barley can follow soyabeans, potatoes, groundnuts or tobacco in a rotation, but it may be difficult to follow late maturing crops such as maize cotton and sunflower. To prevent contamination from previous crops a field used for wheat or barley seed crop should not have had any wheat or barley crop in the previous season for certified seed, and in the previous two seasons for basic seed. To reduce a build up of soil borne diseases, a minimum of three seasons is preferable.
Wheat and barley are strongly self pollinated crops with the anthers bursting inside the flowers and shedding pollen before they open. Only under exceptionally dry conditions would cross pollination be expected to occur and even then not usually above 1 %. However, some isolation is desirable, mainly to prevent physical admixture of one crop with a neighbouring crop. A distance of not less than five metres is required for certified seed and ten metres for basic seed.
