Use of Olive-Mill Wastewater for the Containment of Phelipanche ramosa in Open Field of Processing Tomato Crop

Phelipanche ramosa (L.) Pomel is a root holoparasitic weed that infested many crops, particularly the processing tomato. In semi-arid regions of world, this problem increasing, both in intensity and acreages. last few years, researches for control parasite has increased its effort to use suitable methods, as well utilization natural compounds. regard, four experimental trials were carried out over three growing seasons (2014, 2016 2017), at Foggia (Apulia Region, Southern Italy), open field, on tomato (cv. “Dres”) crop, by P. ramosa, where olive-mill wastewater (OMW) was incorporated into soil dose 80 m3 ha-1 40 days prior seedling transplant comparison with untreated control. The numbers emerged shoots (branched plants) significantly lower OMW treatment than marketable yield showed higher value No significant differences fruit qualitative characteristics observed.
