Reducing greenhouse gas emission by alternation of the upland crop rotation in the Mekong Delta, Vietnam

نویسندگان

چکیده

Agricultural production is one of the main sources anthropogenic greenhouse gas (GHG) emissions, contributing 50% and 60% CH4 N2O respectively. This study evaluated rice yield components, emissions global warming potential between triple (R-R-R) sesame-rice rotation (S-R-R) systems in Can Tho city, Vietnam. The experiments were conducted 3 cropping seasons: Spring-Summer 2016, Summer-Autumn Winter-Spring 2016-2017. results showed that there was no significant difference components grain systems. application sesame rice-based could reduce emission by 30.5% 18.7%, Global S-R-R 9860 kg CO2e/ha, significantly lower than R-R-R (12410 CO2e/ha) 20.6%. These show has to mitigate GHG especially CH4, which contributes a large amount cultivation.

Tillage effects on energy use and greenhouse gas emission in wheat-cotton rotation

Crop production process utilizes input energy and produces some biomass energy as output.  During this process, greenhouse gases (GHGs) are also emitted which can make environmental risks. In this study, input and output energies, energy indices, and GHG emissions arising from inputs were estimated for wheat-cotton rotation under different tillage practices in Fars province. The study was condu...
