S. Milligan, Report on the Present Position of the Agricultural Industry and the Necessity, or Otherwise, of Encouraging Further European Settlement in Agricultural Areas (Livingstone: Government Printer, 1931).

Arable farming by Europeans may be stated to have made a beginning with the advent of settlers following on the opening of the railway to Broken Hill. Maize has all along been the chief crop on the farms. The agricultural area in Northern Rhodesia stretch along the railway line from Pemba in the south to Chisamba in the north. Probably not naturally so fertile as those met with in some other maize producing countries, they possess considerable advantages from the point of view of arable farming. Yields are generally accepted as being higher in the case of the tractor, and it only requires an additional half bag of maize to cover the difference in cost. A plentiful supply of cowpea hay, added to the leaves and stalks of maize and groundnuts, would form a sound basis for animal husbandry in the arable areas. In growing maize on new land in Northern Rhodesia the first crop is generally a poor one.
