The terms “small farms” and “large farms” are used in many tables in this Section. “Large farms” are those which used to be included in the former “Scheduled Areas” less those which have been transferred for sub-division into settlement schemes. “Small farms” include all other areas of arable farming covered in the surveys from which data set out in this Section are derived. Surveys covering the small farms areas started on a limited basis and have been gradually expanded so that they now cover all significant areas of arable farming. In a few districts, e.g. Uasin Gishu, farming is predominantly carried out on large scale holdings. However, they have some areas under small farm settlement schemes. In such cases of predominantly large scale farming the small farms have been brought into the basic agriculture statistics surveys.
The small farms are between 0.2 and 12 hectares though there are some outside this range. In large scale farming districts namely, Nakuru, Uasin Gishu, Trans-Nzoia, Kericho, Nandi and Laikipia, the average size of farms is around 700 hectares. Overall, 25 per cent of the farms range between 20 and 50 hectares.
Most production and price figures shown in the tables refer to calendar years. For this reason they would in some instances differ from data published by marketing organizations in so far as these bodies publish data on other than calendar year basis. Other differences may be due to the fact that a product and its price might be shown at a different stage of processing.
Statistics on value of marketed production are derived from quantities and average prices realised by farmers for commodities delivered to various marketing agents. Attempts are made to estimate value of other production not directly delivered to the boards.
Data on small farms have been collected by means of sample surveys that are subject to sampling errors as well as possible non-sampling errors at district level.
