| With regard to the limitation of energy resources, especially non-renewable sources and increasing trend of energy consumption in agriculture, energy management in this sector is important. The purpose of this study was assessing energy productivity, input and output energy, energy efficiency and output-input energy ratio of sugar beet production in west Azerbaijan province of Iran. To achieve these objectives, statistical data about cultivation area, sugar beet yield in 2010 were acquired from the agricultural research center of west Azerbaijan province. Also data about cultivation methods, implements and machinery in use were obtained from sugar beet farmers by questionnaire. According to the results, total energy consumption in sugar beet production was... |

| Energy inputs and yield relationship in cassava production was investigated to establish correlation between inputs and output in cassava production in Nigeria. Production data of energy inputs and crop yields were collected from 54 cassava farms in twelve cassava producing villages through site visits, interaction with the farmers and physical measurements for three production seasons (2013-2016). The data were analyzed statistically. Amount of inputs per hectare were calculated and multiplied by coefficients of energy equivalents. Total energy inputs in cassava production in this study was 36,482.8 MJha-1 while average output of cassava tubers was 32, 022.6 kgha-1. Energy use ratio, energy productivity and specific energy of the surveyed farms were 4.9,... |
