Abstract

The study sought to evaluate the influence of cross slope on the performance of three pneumatic feeders submitted to different operation speeds using soybean seeds. The work was conducted at the Laboratory of Research and Development of Agricultural Machinery (LASERG), located at the Universidade Federal de Santa Maria, with the aid of a workbench that simulates certain operating conditions of sowing, such as variation of speed and slope of feeders. A randomized block design was used with split plots and three experimental factors: cross slope of three seed metering levels (± 11 ° and leveled), three pneumatic seed feeders and three operation speeds (5, 7.5 and 10km.h-1). Measuring consisted of evaluating 250 spacings per repetition. For the regularity of distribution the percentage of acceptable, double and flawed spacing was evaluated, and by the coefficient of variation of the data collected in the seed feeder. The results showed that increasing the seed spacing was influenced by variation of the operation speed, significantly impacting the average results of acceptable and flawed spacing, as well as precision. For the slope factor there was significant difference according to the Tukey test.
