The first census of agriculture, conducted in 1949/50, and the second, conducted in 1959/60, both were organized by the Ministry of Agriculture, while the third, conducted in 1969/70, the fourth, conducted in 1979/80, and the fifth, conducted in 1989/90, which were organized by the Bureau of Statistics.
The 1989/90 census complements the annual statistical survey on crops and livestock production started in 1973. The census was conducted by the Bureau of Statistics (BOS), which was responsible for its planning, organization, data collection, processing, analysis and tabulation; administrative and financial responsibility was also with the BOS. Objectives and coverage of the census were determined in collaboration with a coordinating committee which also included the Ministry of Agriculture. Data generally refer to the agricultural year August, 1 to July, 31. Data on livestock refer to August 1st 1989.

Frame: The 1986 Population Census data were used as a sampling frame for the agricultural census. The frame of Primary Sampling Units (PSUs) was prepared by district (ten) and, within district, by agro-ecological zone (four).
Methods: A stratified multi-stage sampling scheme was adopted (excluding prisons and project farms which were completely enumerated). Enumeration areas constituted the PSUs and individual agricultural holdings (farming households) constituted the Secondary Sampling Units (SSUs) for estimation of land use, crop areas and livestock population. Fields under specific crops formed the secondary sampling units for estimation of crop yields. 120 PSUs and over 3000 holdings were selected, there being about 25 selected holdings in each PSU. The PSUs were selected with probability proportional to size, the size estimate being obtained from the 1986 Population Census. In each PSU, the 25 agricultural households were selected through systematic sampling from a list of all agricultural households. Data on crop areas were obtained using actual measurement of all fields on selected holdings.
