Evaluation of Plant Distribution Regularity in Sowing With Different Guidance Systems by GPS, GIS and Voronoi Polygons

In this study, sowing was carried out with 3 different tractor guidance methods: operator-controled, GPS-controled and automatic-controled. The optimum nutrient areas required for each plant were evaluated using voronoi polygons. Voronoi polygons used to obtain areas. living spaces. coordinates taken CORS-RTK GPS loaded into the CBS program polygon obtained. Comparison of made shape coefficients calculated area perimeter values. Shape coefficient 0.731 in operator-controlled application, 0.746 GPS-controlled application 0.715 automatic-controled application. Compared found be 2 % more less automatic-controlled Although are relatively system, it can seen that better results obtained terms field success due advantages such as low workload on operator, ease at night improvements time utilization coefficient. As a result statistical analysis, has been there is no difference between applications interchangeably. result, when systems compared other, successful.
