Sažetak
U radu su prikazani rezultati poljskih ispitivanja devetoredne povrtarske pneumatske sejalice, pri setvi crnog luka. Analizom rezultata ispitivanja utvrđene su razlike u preciznosti rasporeda isejanog semena u redovima i po dubini setve u funkciji promene brzine kretanja (4,28 kni/h, 4,80 km/h i 7.58 km/h). Testiranjem razmaka isejanih semenki između pojedinih redova na sejalici utvrđeno je da ne postoje statistički značajne razlike. Povećanjem radne brzine povećava se razmak isejanih semenki u redu (5,63; 5.70 i 6,85 cm). U intervalu od -0,5 do 0,5 cm u odnosu na zadatu dubinu učestalost isejanog semena je najveća za sve tri radne brzine.
Abstract
The work presents the resultants of filed investigation of nine row precision vacuum planter for vegetables in sowing of onion seed. By analysis of the results of investigation differences have been found in the preciseness of distribution of the seed sown in rows and seeding depth in function of working speed (4,28 km/h, 4,80 km/h and 7,58 km/h). Testing of distance sowing seeds between rows at planter was detected no statistically significant differences. Increasing of working speed was increased distance sowing seeds (5,63 cm, 5,70 cm and 6,85 cm). In the breach from -0,5 cm to 0,5 cm of the depth seedling assigned have been the most sowing seeds for all three work speed.
