The amount of energy consumption in each group of inputs was calculated from the multiplication of the amount of the input consumption and its energy equivalent per unit (extracted from scientific sources). Then according to energy input and output, energy use efficiency, energy productivity, specific energy, and net energy were calculated. (1)Cited by: Energy plants (crops), Biogas, Methane. comparative study of new energy crops has been conducted. Its aim was to give a comparative assessment of the main technological parameters for biogas production. Samples of the following energy crops were examined: four species of Paulownia hybrid, Shan Tong, Kawakamii and Elungata, Willow, Miscanthus. Organic farming is generally a more energy efficient system of food production. Comparative analyses of fifteen crop and livestock sectors indicate that UK organic farming uses around 26% less energy per tonne of output on average. The main energy saving is from the non-use of industrially produced inorganic nitrogen fertiliser. Organic farming is more energy efficient for Cited by:   Abstract. Efficient use of energy helps to achieve increased production and productivity and contributes to the economy, profitability, and competitiveness of agricultural sustainability of rural communities. Evaluation of wheat and barley production systems in view of energy balance was conducted in Khorasan Razavi Province, by: 3.

Highest Consumption energy to production energy ratio for rice varieties under to farming system was observed in Hashemi rice. Energy balance efficiency (production energy to consumption energy ratio) in this study was calculated and ; showing the affective use of energy in the agro ecosystems rice paddy by: 5. machinery, electricity, fertilizers, seeds and output energy included 16 agricultural crops yield. Energy values were calculated by multiplying the amounts of inputs and outputs by their energy equivalents with the use of related conversion factors. The energy efficiency is determined by dividing the output value by the input Size: KB. A collection of resources on farm energy efficiency and conservation topics, including farm buildings, greenhouses, livestock production and buildings, farm equipment, crop systems, irrigation, or the food system. Resources include publications, factsheets, checklists, tip sheets, Web links, and FAQs.   Synthetic herbicides account for only 10 percent of the energy consumption of conventional corn production in the Rodale tests, and the pesticides even less than that. (Such chemicals are off.

  Energy use efficiency, energy productivity and specific energy were determined as , and respectively in apple production by not applying good agricultural practices. Relative profit values in apple production were calculated respectively as and , by dividing the gross production value by production costs per : Başak Aydın, Duygu Aktürk, Erol Özkan, Harun Hurma, Mehmet Ali Kiracı. The intensive use of the existing and new energy crops could bring about a greater multi-functionality of agriculture, as well as comparative cost/benefit stability .
