Differences in costs of sample surveys between regions and farm sizes in the State of Sao Paulo



Differences in costs of sample surveys between regions and farm sizes in the State of Sao Paulo



Agricultura em Sao Paulo 37(1): 79-87



Studies were carried out in Sao Paulo, Brazil, in 1987 to determine whether or not there were differences in survey costs between the different regions of the state and different farm sizes, using a questionnaire and variance analysis, least squares and Tukey tests. The results showed that the average time spent in travelling was 56 minutes, with a maximum of 86 minutes and a minimum of 45 minutes.
