This study analyzed the energy-use efficiency (EUE) and greenhouse gas (GHG) emission of traditional and partly mechanized rice production systems in Chota Nagpur Plateau, India. Data pertaining to agricultural inputs, field operations, and outputs was collected from rice growers randomly selected from two villages of the region using a specially designed questionnaire. The EUE and GHG emissions were estimated for rice production in traditional and partly mechanized system. Results revealed that the total input energy for traditional system was 5234.95 MJ ha−1 in which farmyard manure (33.42%), human energy (27.98%), animal power (26.52%), traditional tools (7.44%), and seed (1.87%) were the main contributors. The total energy required for partly mechanized system production was 6495.73 MJ ha−1, wherein FYM (32.33%), human labor (30.68%), traditional tools (6.77%), and machinery (2.85%) had considerable shares. The EUE was 7.38 for partly mechanized and 6.87 for traditional system, respectively. The estimated total GHG emission was 3852.26 and 1923 kg CO2 eq. ha−1 for traditional and partly mechanized, respectively. The study concludes that the use of small farm machinery may be promoted in the region to reduce the operational drudgery to humans and animals used in the rice production process. The study further indicated that rice production have distinct energy-use patterns and that the management of energy intensive resources like animal power, human power, farmyard manure and machinery are possible pathways to improve energy efficiency and reduce total GHG emission in traditional and partly mechanized systems of rice production in the Chota Nagpur Plateau.

摘要

This study analyzed the energy-use efficiency (EUE) and greenhouse gas (GHG) emission of traditional and partly mechanized rice production systems in Chota Nagpur Plateau, India. Data pertaining to agricultural inputs, field operations, and outputs was collected from rice growers randomly selected from two villages of the region using a specially designed questionnaire. The EUE and GHG emissions were estimated for rice production in traditional and partly mechanized system. Results revealed that the total input energy for traditional system was 5234.95 MJ ha−1 in which farmyard manure (33.42%), human energy (27.98%), animal power (26.52%), traditional tools (7.44%), and seed (1.87%) were the main contributors. The total energy required for partly mechanized system production was 6495.73 MJ ha−1, wherein FYM (32.33%), human labor (30.68%), traditional tools (6.77%), and machinery (2.85%) had considerable shares. The EUE was 7.38 for partly mechanized and 6.87 for traditional system, respectively. The estimated total GHG emission was 3852.26 and 1923 kg CO2 eq. ha−1 for traditional and partly mechanized, respectively. The study concludes that the use of small farm machinery may be promoted in the region to reduce the operational drudgery to humans and animals used in the rice production process. The study further indicated that rice production have distinct energy-use patterns and that the management of energy intensive resources like animal power, human power, farmyard manure and machinery are possible pathways to improve energy efficiency and reduce total GHG emission in traditional and partly mechanized systems of rice production in the Chota Nagpur Plateau.
