Energy inputs – yield relationship and cost analysis of kiwifruit production in Iran

Determination of Energy Input-Output Analysis in Plum (Prunus domestica L.) Production

“…In terms of plum production, it is noteworthy that chemical fertilizers were the highest input. Similarly, in previous researches related to agricultural production, Demircan et al (2006) calculated that the fertilizer application energy had the biggest share by 45.35% in sweet cherry, Celik et al (2010) calculated that the fertilizer application energy had the biggest share by 33.19% in conventional black carrot, Canakci (2010) calculated that fertilizer application energy had the biggest share by 40.22% in pomegranate, Kizilaslan (2009) calculated that fertilizer application energy had the biggest share by 42% in cherry, Ozkan et al (2004) calculated that fertilizer application energy had the biggest share by 36.48% in citrus, Goktolga et al (2006) calculated that fertilizer application energy had the biggest share by 44.44% in peach, Mohammadi et al (2010) calculated that fertilizer application energy had the biggest share by 47.23% in kiwifruit production etc.…”

“…On the other hand, continual growth of energy prices threats the global agricultural sector. Hence, in order to promote the agriculture section as an economical system; it is necessary for efficient use of energy sources (Mohammadi et al 2010;Beigi et al 2016). Different researches were performed on energy inputoutput analysis of agricultural products.…”

“…Different researches were performed on energy inputoutput analysis of agricultural products. For example, researches were performed on energy input-output analyses of (Ozkan et al 2004), peach (Goktolga et al 2006), apricot (Gezer et al 2003), kiwifruit (Mohammadi et al 2010), apple (Gokdogan and Baran 2016) etc. Although many experimental works were performed on energy usage in agriculture, there is no study on the energy analysis of plum production in Turkey.…”

Energy input-output analysis of guar (Cyamopsis tetragonoloba) and lupin (Lupinus albus L.) production in Turkey

“…By adding energy equivalents of all inputs in MJ unit, the total energy equivalents have been computed. Mohammadi et al (2010) reported that, "The energy ratio (energy usage efficiency), energy productivity, specific energy and net energy have been computed by using the following formulates (Mandal et al, 2002;Mohammadi et al, 2008) " .…”

Determination of energy balance of common vetch (Vicia sativa L.),hungarianvetch (Vicia pannonica C.) and narbonne vetch(Vicia narbonensis L.) production in

“…By adding energy equivalents of all inputs in MJ unit, the total energy equivalents have beencomputed.) The energy ratio (energy usage efficiency), energy productivity, specific energy and net energy have been computedby using the following equations (Mandal et al, 2002;Mohammadi et al, 2008 andMohammadi et al 2010 Kocturk and Engindeniz (2009) reported that the input energy can also be classified into direct, indirect, renewable andnon-renewable forms (Mandal et al, 2002;Singh et al, 2003)". Total fuel consumption of each parcel has beencomputed as l ha -1 .…”
