Abstract:
The estimates of potential biomass production from pruning in olive often follow generic indications not considering varietal differences, training and pruning systems. The main limitation to the valorization of pruning concerns the collection-logistics chain which requires precise starting data, often linked to specific production areas. Traditional groves still represent the majority of the Italian olive cropping systems. Information about intensity and type of rejuvenation pruning is still lacking for these orchards and data from different climatic conditions are important for further planification of new power plants for energy valorization. This study evaluates the biomass produced from two rejuvenation pruning intensities (i.e. intense and light) in five Italian cropping systems in two consecutive years. In the first year, the amount of removed material per tree was correlated to the initial canopy volume within treatment so that the biomass produced with intense pruning in the cultivars with bigger tree size passed 30 t ha-1. In both years, shreddable material was the prevalent fraction (>50%) in the tested cultivars and for both pruning treatments. Even adopting the lowest calorific value of 14.4 MJ kg-1 of dry matter, the energy potential appears promising for a possible economic valorization of the biomass.
