In this study, various Artificial Neural Networks (ANNs) were developed to estimate the production yield of greenhouse basil in Iran. For this purpose, the data collected by random method from 26 greenhouses in the region during four periods of plant cultivation in 2009–2010. The total input...

The aim of this study was to determine the amount of input–output energy used in potato production and to make an economic analysis of potato production in Hamadan province, Iran. Data for the production of potatoes were collected from 100 producers by using a face to face questionnaire...

Among the different forms of clean energies, solar energy has attracted a lot of attention because it is not only sustainable, but also is renewable and this means that we will never run out of it but the potential of using this form of renewable energy depends on its accessibility. Due to the...

This paper studies the energy balance between the input and the output per unit area for greenhouse cucumber production. For this purpose, the data on 43 cucumber production greenhouses in the Tehran province, Iran, were collected and analyzed. The results indicated that a total energy input of...

In recent years, besides the energy issues, the GHG (greenhouse gas) emission, which is the most important cause of global warming, has received high attention. In order to have sustainable development, it is necessary to manage energy usage and GHG emissions in all production processes. This...

The main purpose of this study was to determine energy use efficiency in greenhouse cucumber production using a non-parametric production function. Energy use efficiency of greenhouse cucumber producers was studied and degrees of technical efficiency (TE), pure technical efficiency (PTE) and...
