Orphan uses gradually occur in seed production. So, the experiment system “AgroSem” aims to produce quality seeds without using chemical pesticide. From 2018 to 2023, three similar cropping systems were implemented on three locations with an 8 years rotation on 8 plots. The chosen crops were mainly seed production of wheat, pea, alfalfa, beat root, carrot, bean and onion. The treatment frequency indicators were drastically reduced. But, working time has been often higher than references because of crop establishment choices, mechanical weeding and punctual resort to manual weeding. Hence, production charges were often upper than references. Among the 105 crops, 61 gave a smaller yield than the references, 18 were close (references +/- 10 %) and 26 gave a higher yield. Quality was frequently good, except for peas which has a bad germination.
