This interesting topic stimulated the curiosity of the attendees that lead a discussion, focused on especially the effects of this technique on the vine growth and diseases, but Alessandro confirmed that no increasing in diseases nor in competition were observed in his production context.
Afterwards, together with our expert in farm mechanization, prof. Christian Frasconi, the machines used in the farm for the management of the weeds and the cover crops were shown. Among these, the innovative roller crimper built by Dondi s.r.l., called “Rotovitis” that have the possibility to increase its weight adding ballasts to improve the devitalization of the most productive cover crops producing a large amount of biomass.
Other interesting machinery showed were the rollhacke and the finger weeder, tools developed for the under row weed management. In conclusion, dr. Lorenzo Gagliardi, a PhD student in farm mechanization at Department of Agriculture, Food and Environment, presented a power point concerning some trials that our research group carry on at Castellani farm using the innovative machinery presented before.
On this regard, the first trial reported was about different strategies for the under row weed control using combinations of the tools presented before (compared with traditional mechanical methods), while the second one regarded the use of the roller crimper “with” and “without” ballasts to evaluate the capacity of devitalization of the cover crops.
