Résumé:
It was studied the hydraulic performance of trickle irrigation emitters. The analyses was based on the manufacturing variation coefficient and the characteristic equation. The emitter types tested were the Eindor, Fanjet-Black, Fanjet-Orange and the Microjet. The results showed that the Eindor, Fanjet-Black and Fanjet-Orange emitters are excellents in their manufacturing qualities, while the Microjet emitter showed to be of a reasonable quality. The power type characteristic equations resulted in correlation coefficients (r2) around 0.99.
