“…Based on these results, the benefit-cost ratio from garlic production in the farms was calculated to be 1.36. These results are consistent with the findings reported by other authors, such as 1.83 and 2.21 for greenhouse and open-field grape (Ozkan et al, 2007) and 1.10 for soybean, 2.03 for wheat, 1.98 for mustard and 2.30 for chickpea (Mandal et al, 2002), 2.58 and 1.88 for cucumber and potato, respectively (Mohammadi et al, 2008, Mohammadi andOmid, 2010 ) by total production costs (6969.11 $ ha -1 ). Table 6 shows the rate of MD in percent in each of machinery operations in garlic cultivation in different levels, separately.…”

This paper studies the energy balance between the input and the output per unit area for garlic in Hamedan province of Iran. In this study, data were collected by using random sampling method for 136 face to face questioners. Results showed that the highest share of energy consumption belongs to chemical fertilizers (41.7%) followed by diesel (13.94%). The results indicated that a total energy input of 40307.89MJ ha -1 was consumed for garlic production. The energy productivity and net energy value were estimated as 0.416 kg MJ -1 and-13477.82MJ ha -1 , respectively. The ratio of energy outputs to energy inputs was approximately 0.665. The benefit-cost ratio was estimated as 1.36.mechanization degree (MD) was calculated for plowing and disk border were 100% and 20.65%, as the highest and lowest, respectively. The farms of between two to three hectares with 0.89 highest mechanization index (MI) and those Between one to two hectare with 0.6 lowest MI were remarkable.

Alipour A., Veisi H., Darijani F., Mirbagheri B., Behbahani A.G., 2012. Study and determination of energy consumption to produce conventional rice of the Guilan province. Res. Agr. Eng., 58: 99-106.The aim of this study was to determine the energy efficiency indices in the agro-ecosystems of the Guilan province in 2010. One hundred and twenty-seven farmers were interviewed using a particularly designed questionnaire. The inputs in the calculation of energy use in agro-ecosystems embraced labour, machinery, electricity, diesel oil, fertilizers, seeds, while rice and straw yield were included in the output. The results depicted that total input and output energy into these agro-ecosystems were about 47,604 and 90,680.04 MJ/ha, respectively. The highest energy input was related to water (38.84%), electricity (27.87%) and nitrogen fertilizer (17.5%). Energy efficiency and energy productivity in these agro-ecosystems was 2.19 and 0.064 kg/MJ, respectively, and water productivity was 0.11 kg/m 3 . The results also showed that due to application of flood irrigation in these agro-ecosystems and also water elicited from subterranean sources by electrical pump, the inputs had the largest portion among the energy inputs to agro-ecosystems that this matter increased energy use in the unit area and also reduced energy efficiency and productivity.

Energy and water tradeoffs in enhancing food security: A selective international assessment

Rice is the major staple food in most Asian countries. However, with rapidly growing populations, sustained high productivity and yields through improving water productivity is critically important. Increasingly complex energy-agriculture relationships require an in-depth understanding of water and energy tradeoffs. This study contributes to energy and food policies by analysing the complex energy, water and economics dynamics across a selection of major rice growing countries.The results show that tradeoffs exist between yield and energy inputs with high yield attributed to higher levels of energy input. The selected developed countries show higher energy productivity, relative to all other energy inputs, compared to the selected developing counties, owing to enhanced mechanisation, onfarm technology and improved farm management. Among all countries, China has the highest water productivity due to water-saving irrigation practices. These practices offer opportunities for developed and developing countries to increase water productivity at the same time taking advantage of economic and energy benefits of 1 Correspondence to: Shahbaz Mushtaq.

While greater water productivity will almost certainly be necessary to reduce the negative impacts of future water scarcity, it is crucial to bear in mind the trade-off between energy and water productivity. Development of efficient water irrigation practices such as alternate wetting and drying irrigation practice and their large scale implementation across the countries will result in increased rice productivity, reduced energy dependency, natural resource sustainability and ensure long term food security.

Since the Green Revolution of the 1960s, the combination of new high yielding rice varieties has resulted in the dramatic and sustained increase in rice production. This increased productivity and profitability also contributed to enhanced food security and less poverty among farmers with irrigated land (Dawe, 2000).Rice is one of the largest users of the world's developed freshwater resources (Tuong and Bouman, 2003).
