Resumo: | The objective of this study was to evaluate two harvester displacement speeds (2.5 and 3.5 km h-1) and three adjustments for track rotor rotations (500, 700 and 850 rpm), in the occurrence of mechanical damage to grain. Chickpeas. Harvesting was carried out in a commercial production area. Seeds were evaluated for purity, germination, first count, germination speed index, hypochlorite test, electrical conductivity test and tetrazolium test. There was an effect of machine displacement speed on seed physiological quality (PC, G and IVG), especially at high rotor speed. In these cases, the speed of 2.5 km h-1 resulted in lower values. This speed also revealed worse results at 850 rpm for purity and hypochlorite. Tetrazolium was not efficient to identify differences in seed quality. There was no significant interaction for the conductivity test. The evaluation of the isolated effect of the displacement speed identified that at 3.5 km h-1 there are problems in seed vigor due to the greater exudate release. Low harvester travel speeds (2.5 km h-1) associated with high rotor speed of the track (700 and 850 rpm) cause reduction of the physical and physiological seed quality. |

Harvesting was carried out in a seed production field. Seeds were evaluated for purity, germination (G), first count (FC), germination speed index (GSI), hypochlorite, electrical conductivity, and tetrazolium tests. There was an effect of harvester speeds on seed physiological quality for the first count (FC), germination (G), germination speed index (GSI), especially when combining with high rotor rotation speed. In these cases, the speed of 2.5 km.h-1 resulted in lower values. This harvester speed also had worse results when combining with 850 rpm for purity and hypochlorite tests. The tetrazolium test was not efficient in identifying differences in seed quality. There was no significant interaction between harvester speeds and rotor rotation speeds for the conductivity test. Evaluating the harvester speed’s isolated effect (3.5 km.h-1), we identified problems in seed vigor due to the higher value of exudates in the electrical conductivity test. Low harvester speed (2.5 km.h-1) associated with high rotor rotation speeds (700 and 850 rpm) causes a reduction of the physical and physiological quality of seeds.Universidade Federal de Viçosa - UFV2021-03-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/1090710.13083/reveng.v29i1.10907Engineering in Agriculture; Vol. 29 No. Contínua (2021); 28-35Revista Engenharia na Agricultura - REVENG; v. 29 n.
