Scientilic papers of six wellknown international journal of agricultural research (Agronomy Journal, Crop Science, Plant Physiology, Phytopathology, Plant Disease, Journal of Economic Entomology) and the Revista ICA of Colombia, were revised taking the 1990-1992 years as a sample periodo The objective of this review was to evaluate the frequency of the experimental designs commonly used in agricultural research, to observe the statistical techniques more frequently applied in data analysis, and to assess the importance and acceptance of these statistical tools in agronomy. According to the results, the Randomized Complete Block Design and the Completely Random Design were observed in 71% of the experiments. The Fisher LSD was used to separate treatment means in 49% of the cases. The frequency of factorial experiments, regression analysis, subsampling techniques and repetitions in time and space were also analized. Despite of the size of some experiments with more than 50 treatments, the frequency of incomplete Block Designs was very low.
