RESUMO
This work was developed in the experimental field of Agricultural Engineering CoI: of State University of Campinas, and it had as objective to evaluate the new system of tillage in strip conservationist with Rotary "Paraplow", it was given emphasis for application in seeding systems appropriate for small fanns. The evaluation was divide( three groups: characterization of tool as conservationist; geometric characterization of st determination of operation configuration for small fanns. It was used the dimensional analysis method for to define the experimental plannin, having been determined which parameters should be measured. These parameters, in a tota twenty two, they were arrangement in a experimental design completely random, where t were realized the experiment with eight treatments, each treatment was allocated in experimental strip, with five points of obtaining data, before and after the action of the tI for these arrangement were made two repetitions for each parameter, totalizing sixt experimental strips, with ten point of obtaining data for each treatment. With these data it possible to realize the analysis through: descriptive statistical; dimensional analysis; . variance analysis. The results demonstrate that the Rotary "Paraplow" is a tool of soil till conservationist. The evaluations show that this tool coupled with tiller with 12 cv appropriated for small fanns, it have been compatible field capacity with the needs of sn fanns. Comparisons between the methodologies of dimensional analysis and the varia: analysis of one way, showed the superiority of the dimensional analysis in studies of ~ dynamics and evaluations of soil tillage machines
