Pruning is a vital method involving the selective removal of undesirable portions of the apple plant, which generates substantial quantities of residual material. The research focused on measuring the quantity of apple residue produced by trees of varying ages and analyzing the characteristics of these residues for potential energy generation applications. The data pertaining to pruned wood generation were systematically gathered from commercial orchards of varying age cohorts situated at diverse elevations within the apple cultivation zone of Shimla. The pruned wood was measured in the field, and a proximate analysis was conducted. The findings demonstrated that the mean pruned wood yield ranged from 3.95 to 10.19 kg/tree, measured on a dry basis. The generation rate of pruned wood in the region is quantified at 8 to 14 tons per hectare per year. The moisture content of pruned residue was observed to range from 42% to 46%, while the ash content varied between 3% and 3.5%. The calorific value was recorded within the range of 17.00 to 18.53 MJ/kg, and the energy potential exhibited a range from 88.93 to 260.51 MJ/t. In the context of various disposal methods, it was observed that open burning emerged as the predominant practice in the study area, potentially leading to an increase in carbon dioxide emissions. Given the substantial generation of pruned/trimmed residue and its associated calorific value, it presents a viable option for serving as an energy source to fulfill the requirements of various industrial applications and local heating systems.
