Evaluating the level of mechanization in the selected dual-purpose farms of Central Province

This research was conducted with the aim of investigating the effectiveness of the mechanization status on energy efficiency in the dual-purpose farms of rainbow salmon breeding in the central province. This research was conducted by field method and through the analysis of questionnaire data regarding the state of mechanization in the farms of this province. For this purpose, after designing the questionnaires, the input information includes the area of cultivation and equipment such as feeding system, electric pumps, drainage pump, diesel generators and fans. The farms have been selected from 5 cities of Central Province, including 30 production units that have the largest share. Then the outputs, including degree, capacity and mechanization level, as well as production efficiency, production capacity, and energy efficiency were calculated by multi-input-output modeling and data envelopment analysis (DEA). The results showed that the variance of the degree of mechanization in the farms of this province is 0.96. Also, considering the optimal efficiency index level of 1 for farms, it was observed that 40% of farms in this province are in a favorable condition. The results of examining the performance of each unit in terms of energy efficiency index also showed that only 20% of farms in the province have an efficiency index higher than 0.4, and 80% have an energy efficiency of less than 1. The results show that the distribution pattern of mechanization in all farms of the province is not uniform and needs to be improved.
