Tillage and irrigation methods effects on energy use and greenhouse gas emissions in grain corn production CIGR Journal
Afzalinia, Sadegh.
In this study, the effect of tillage and irrigation methods on energy use, energy indices, and greenhouse gas (GHG) emissions of grain corn production was evaluated. The research was conducted in the form of a split plot experimental design with three replicates in Fars province, Iran. Main plots were irrigation methods including surface irrigation (gated pipe), drip irrigation, and sprinkler irrigation. Tillage methods including no-till (NT), reduced tillage (RT), and conventional tillage (CT) were considered as sub plots in this research. Results showed that irrigation method had significant effect on energy use, output energy, energy indices, and GHG emissions of grain corn production, while tillage method had significant influence only on energy use,...

Modeling and optimization of energy consumption for grape fruit productionin Iran CIGR Journal
qasemi kordkheili, peyman.
Grape fruit production has increasing rate in recent years. In this study a non-parametric method of Data Envelopment Analysis (DEA) has used to estimate the energy efficiency of grape fruit production orchards in Sari region of Iran. Additionally, the impacts of energy inputs on grape fruit yield were determined. Data were collected using a face-to-face questionnaire method from 71 orchardists in winter 2014. The results showed that the total energy consumption was 49.8 GJ ha–1 and chemical fertilizers by 28% of this quantity had highest share on total input energy. The results of CCR and BCC models of DEA showed that from total of 71 orchardists, only 21 orchards were technical efficient by efficiency score of 1 and 43 orchards were pure technical...
