“…Similar issues with low efficiency energy consumption in production of various crops in developing countries, including Iran, have previously been reported (e.g. Canakci & Akinici, 2006;Ozkan et al, 2007;Mohammadi & Omid, 2010). However, new policies by the Iranian government aim to gradually eliminate subsidization of fossil fuels which may put pressure on growers to implement more energy efficient practices.…”

Pistachio is considered as an important agricultural commodity in Iran and ranks top amongst all exported agricultural products. Conducting an overall energy audit and economic analysis of pistachio production can provide useful information to help implement management strategies for improving energy efficiency. A study was conducted during 2009 and 2010 to evaluate the overall energy inputs and outputs and to perform an economic analysis of pistachio production in the Iranian province of Markazi. The results revealed that the total energy input for pistachio production was 54305 MJ ha -1 . Electricity, followed by diesel fuel and nitrogen fertilizer application were the highest contributors to energy input in pistachio orchards. The contribution of direct energy was higher than indirect energy and share of non-renewable energy was more than renewable energy. Net energy, energy use efficiency, energy productivity and specific energy were 7522 MJ ha -1 , 0.86, 0.08 kg MJ -1 and 13.69 MJ kg -1 , respectively. Econometric model based on Cobb-Douglas function indicated that impacts of electricity, diesel fuel and chemical fertilizer energy inputs on pistachio yield were positive while the impact of machinery was negative. The marginal physical productivity (MPP) value for diesel fuel was the highest among other variables, followed by energy inputs related to the chemicals and irrigation water. The results revealed that production of pistachios in Markazi Province, under current management practices, are not energy efficient and efforts should be made to improve energy use efficiency.Additional key words: econometric model; energy use efficiency; renewable energy; sustainability.

“…About 78 % of this was generated by diesel fuel, 10 % from chemical fertilizers and 4.5 % from electricity. Analysis of energy use in various greenhouses producing vegetables in Turkey has been reported (Canakci and Akinci, 2006 (Ozkan et al, 2004). The authors studied 88 greenhouse farms cultivating tomato, pepper, cucumbers and eggplants through the use of questionnaires.…”

“…Water content of soil is an important component in greenhouse, which has a direct impact on the amount of water used to irrigate crops. Greenhouse cultivation is of various types in many parts of the world and is considered as an expensive method to produce a number of products (Canakci and Akinci, 2003). Furthermore, the main goal of greenhouse development is to improve productivity and efficiency of water consumption (Hasandokht, 2005).…”

Measurement and control of water content of soil is an essential factor in irrigation management, to apply the best management practice for reducing water consumption and improving product quality. The water content of soil is an important factor in greenhouse where it is directly related to the total amount of water consumed for irrigation. Since cucumbers (Cucumis sativus L, Nasim variety) is considered as the main and much used summer crop in Iran, which are extremely sensitive to adverse conditions particularly water stress, determination and supply of water is vital for this plant. To this end, maximum allowable depletion (MAD) should be determined. This experiment was conducted in the research greenhouse (Plastic Covered) of Islamic Azad University in Khorasgan, Isfahan, during a period of five months. This project was implemented in the framework of three 40, 60, and 80 cm bar water suction treatments with three replications using tensiometer. Before treatment application, water content of soil was determined in weight. MAD in 40, 60, and 80 cm bar treatments was 22, 32 and 50%, respectively. Statistical results and mean comparison demonstrated that MAD of 22 and 32% led to a significant yield increase (P<0.001), while MAD of 50% had the least yield. The results reveal that there was a significant difference between MAD of 22 and 32% in increasing leaf area index (LAI) (P<0.001).
