Considering the importance of dry beans as a food source and how essential is to improve its production, a two years, experiments in 1995/96, and 1996/97, were carried out to evaluate the efficient microorganism (EM) fertilizer action in comparison to the NPK traditional chemical fertilization. The experiments were done at Federal University of Paraná Experiment Station of Canguiri, in Pinhais, PR, on a Latossolo Vermelho Amarelo Álico soil, prepared on the conventional way, in an uniform area. The EM was tested in six dilution, 1:250, 1:500, 1:750, 1:1.000, 1:1250, and 1:1.500. The product was always applied on the leaves seven times through the cicle, for all the dilution, four in week interval, two in fifteen days interval and one in month interval. The NPK fertilization was defined by the soil analysis. It was applied together with the seeds and complemented by a N cover fertilization. A randomized complete block design with four replications was used. The variables evaluated, just in the first year, were the morphological characteristics: plant stature, stem diameter, node number and leaf number, and in both years, the initial and final stand, the yield components and yield. The results showed that the EM can not be recommended as a substitute to the NPK chemical fertilization and was not found any evidence to indicate one of the dilution to be used.
