Led by a master pruner, the field day first recalled the objectives of pruning and the different approaches according to tree age and condition, before a practical demonstration in the orchard.
The focus was placed on training pruning (single trunk, well-distributed scaffold branches oriented outward) and on fruiting pruning after harvest, with the removal of exhausted, poorly oriented or dry wood, and the thinning of dense shoots to improve light and air circulation. Great attention was given to clean, slightly angled cuts to enhance healing and reduce disease risks. Participants then practiced directly on trees, guided by the trainer.
Post-pruning management, presented by Noureddine Mrabet from the Centre de Formation Professionnelle du Kef, highlighted the importance of a winter treatment (mineral oil combined with copper) during the dormant period, as well as the use of protective pruning sealant on large cuts and the short-term trapping of pests by leaving prunings in the plot for a few days.
The valorisation of pruning residues was introduced by Hazem Cherni (CAPTE). Using a rotor knife shredder, participants produced wood chips and BRF for mulching and composting. The chips were then applied as mulch around young carob trees, illustrating a circular and agroecological approach that improves soil moisture, limits weeds and enhances soil fertility.
The workshop brought together several farmers and representatives of technical institutions and local authorities, notably the CRDA du Kef and the CFPA Kef, deepening exchanges between field actors and support services.
At the end of the day, the representative of the Ministry of the Environment in the governorate of Kef, Mr Kamel Mnasri, welcomed the initiative, emphasising its importance for the preservation of natural resources and climate change mitigation though agricultural practices.
