Abstract

We have tested the tillage combination to study methods that help curtail the release of greenhouse gasses from rice paddy fields have had on the climate and contrasted the potential outcomes for rice production (Oryza sativa L.), no-tillage plus no fertilizer (NT0), conventional tillage plus no fertilizer (CT0), conventional tillage plus compound fertilizer (CTC), no-tillage plus compound fertilizer (NTC) by measuring ammonia volatilization and greenhouse gases emissions (GHG) from paddy fields for rice throughout the year of 2018 in the subtropical area of central China. The mean NH 3 volatilization in CT0 was 9.55% greater than that in NT0 by (p>0.05), and for NTC, it was 11.30% (p>0.05) lower than in CTC. In comparison to CT0, the mean CH 4 emission flux in NT0 was 1.12% (p>0.05) lower, but the mean CH 4 emission flux in CTC was 28.34% (p> 0.05) higher than that in NTC. The mean N 2 O emission flux in NT0 was 174.72% (p˂0.05) lower than in CT0. The average flux of N 2 O emission in CTC was 47.90% (p˃ 0.05) greater than in NTC. We compared the IGWPs based on N 2 O, CH 4 , and CO 2 emission flux. CT0 had the lowest (non-significant) recorded amount at 12097.43KgCO 2 .ha -1 of GWPs, which was only 397.5KgCO 2 .ha -1 lower than that in NT0. CTC had the highest recorded amount at 20042.72KgCO 2 .ha -1 of GWPs, which was 2292.53KgCO 2 .ha -1 higher than that reported in NTC. NTC system to be the superior, sustainable method for mitigating the harmful effects of GHG emissions contributing to the climate crisis by way of rice production in rice paddy fields

期刊介绍： Asian Journal of Agriculture and Biology (AJAB) is a peer reviewed, open access, quarterly journal serving as a means for scientific information exchange in international and national fora. The scope encompasses all disciplines of agriculture and biology including animal, plant and environmental sciences. All manuscripts are evaluated for their scientific content and significance by the Editor-in-Chief &/or Managing Editor and at least two independent reviewers. All submitted manuscripts should contain unpublished original research which should not be under consideration for publication elsewhere. In order to avoid unnecessary delay in publication, authors are requested to comply the following guidelines; differing these, your submission will be returned for additional revision.
