An important factor in increasing the efficiency of decisions made on the results of agricultural research is the use of advanced digital economy technologies. However, in practice, the analysis of empirical results is often limited to a pairwise comparison of means on impact options, without taking into account the realities of the plan of laboratory or field experiments. The possibility of obtaining new knowledge using information technologies for the analysis of empirical data that support algorithms for multiple comparison of means and multivariate analysis of variance is discussed. To implement these algorithms, you do not need to access expensive software products of the Data Mining class (DM); it is enough to have relatively inexpensive statistical data analysis packages such as early versions of SPSS (Statistical Package for the Social Sciences) starting from version 8.0. An example is given to illustrate the effectiveness of using information systems of the Knowledge Discovery class, focused on the data knowledge search.
