Abstract in English:
Uniform seed spacing is considered a fundamental factor in quality and yield for many crops and drill manufacturers continuously try to improve the accuracy in seed placement, according to the cultivation standard requirements. This paper reports the results of tests on the performances of a six row pneumatic precision drill in which the depression into each sowing unit is created by means of flexible pipes that do not start directly from the fan, as in most pneumatic drills, but from an air duct having the function of uniformly distributing the air flow along the working width. Field tests have been conducted, using three graded seeds, to evaluate the accuracy of the single seed metering system, according to ISO 7256/1 standard, and the uniformity of negative pressure, through the measurement of the distance between seeds in the furrow, under two speed conditions (5 and 8 km h-1).
