Study and determination of energy consumption to produce conventional rice of the Guilan province

Abstract

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.

Analysis of energy input-output of irrigated rice production in Jere Bowl Borno State, Nigeria

“…This index is lower and could be as a result of inefficient use of some energy inputs due to inefficient irrigation system. This finding compares closely to Alipour et al (2012) that rice energy ratio in Guilan province of Iran was 2.19 lower than 6.7 rice energy ratio index estimated in Australia by Khan et al (2010). As rice farm practices in Jere Bowl in Nigeria and Guilan province in Iran are considerably not modernized and efficient as in Australia.…”

Energy Budgeting, Data Envelopment Analysis and Greenhouse Gas Emission from Rice Production System: A Case Study from Puddled Transplanted Rice and Direct-Seeded Rice System of Karnataka, India

“…However, the DSR crop was grown under rainfed condition, so no external irrigation was supplemented. For comparison in the literature, Alipour [39] also reported higher irrigation energy in rice production, and another study on the rice production system in India revealed that irrigation and fertilizers have a higher share of energy input [35]. In addition, in another study, the amount of energy inputs consumed in different rice-based cropping systems were reported to be 44-54% for chemical fertilizers and 11-14% of for in India [40].…”
