Evaluation of energy consumption and econometric analysis in greenhouse cucumber production(Case study: Jiroft province)

The objectives of this study were to determine the energy indicators and econometric analysis in greenhouse cucumber production in Jiroft province Iran.For this purpose, the data on 31 cucumber production greenhouses in the Jiroft province, Iran, were collected and analyzed.The results indicated that a total energy input of 146.95GJ ha-1was consumed for cucumber production. Diesel fuel (with 46.8%), chemical fertilizers (with 20.52%) and electricity(18.7) were amongst the highest energy inputs for cucumber production. The ratio of energy output to energy input was approximately0.58.The energy productivity and net energy was estimated as 0.72 kg MJ-1 and -62.2 GJ ha-1. Also, Results indicate 6% and 93.9% of total energy input was in renewable and non-renewable forms, respectively. The regression results revealed thatthe contribution of energy inputs on crop yield(except for Diesel fuel and chemical fertilizers energies) was significant. The human labour energy had the highestimpact (1.25) among the other inputs in greenhouse cucumber production.According to the results, resource management in greenhouses and reduce the consumption of fuel and fertilizer to produce, can increase energy efficiency and productivity were cucumbers.
