A study was conducted in 2009/2010 cropping season in order to determine energy input/out put and productivity of potato and sugar beet production systems in Isfahan province, Central Iran. The data used in this study was based on data collected from growers by using a face to face survey. Total energy consumption and total out put enegy in potato production systems were calculated to be about ...
