Microclimate and Efficiency Analysis of an Olive Rooting Cuttings Tunnel Greenhouse Type under Mediterranean Wintertime Climatic Conditions

Introduction: The rooting of cuttings is a fundamental step in olive tree production. This preliminary favoured by specific environmental conditions, which demand strict and permanent control across the production system. Achieving these conditions poses major challenge for propagators. In this context, greenhouse technique best response most productive method used globally, including Mediterranean regions. study aims to characterize microclimate tunnel-type according wintertime climatic Morocco’s central region assess its performance fostering cutting growth. Methods: Evaluation efficiency based on measured parameters inside outside studied greenhouse. Also, we statistical data processing SPSS software identification regression analysis factors key determining success cuttings. Results: experimentally obtained results clearly show first time that solar radiation factor rooting. type guarantees homogeneous allows reduction 66% external global radiation, decreases transpiration prevents leaf wilting. also system ensures an internal air relative humidity close saturation value generally stable throughout day, with favourable successful However, temperature was too high during daytime very low nighttime, indicating unfavorable conditions. Conclusion: can provide guidelines propagators improve design climate increase yield quality crop.
