Abstract. The shortage of water resources and the decline in soil organic matter (SOM) are important limiting factors affecting the improvement of rice productivity, while alternate wetting and drying (AWD) irrigation and rice straw return are considered favorable mitigation measures. However, its impact on rice yield and greenhouse gas (GHG) emissions, especially nitrous oxide (N2O) emissions, needs to be further clarified, which is essential for the development of agronomic measures for water savings, soil fertilization and GHG reduction. Therefore, we explored the effects of mild AWD irrigation combined with rice straw return on N2O emissions and rice yield through rice pot experiments. This study showed that N2O emissions were mainly affected by urea application and irrigation methods, and urea application was the main reason. Compared with continuous flooding (CF) irrigation, mild AWD irrigation increased cumulative N2O emissions, with an average increase of 28.8 %. In addition, adding rice straw to mild AWD irrigation further stimulated N2O emissions. Compared with CF irrigation, mild AWD irrigation increased the yield-scaled N2O emissions, and the addition of rice straw further promoted the yield-scaled N2O emissions under mild AWD irrigation but reduced the global warming potential (GWP) by 62.9 %. Under the condition of urea application, compared with CF irrigation, mild AWD irrigation reduced nitrogen uptake by rice in the soil and rice aboveground biomass without reducing rice yield. Therefore, mild AWD irrigation combined with rice straw return is a promising agronomic measure to ensure rice yield, reduce the greenhouse effect and maintain or improve soil fertility.

RC1: 'Comment on egusphere-2022-429', Anonymous Referee #1, 29 Jun 2022
The authors conducted a laboratory pot experiment to investigate the effects of mild alternate wetting and drying (AWD) irrigation and rice straw application on N2O emissions in rice cultivation through 15N tracer technique. Their results showed that mild AWD irrigation increased cumulative N2O emissions by 28.8%. Adding rice straw to mild AWD irrigation further stimulated N2O emissions. These evidences have significance for monitoring N2O emissions in paddy fields. However, I still have some comments here for the authors to address before it’s ready for publication.
For several places, there are something important missing for the authors to have their conclusions.
For example, in abstract L33-36 “mild AWD reduced GWP by 62.9%”, but there is neither GWP calculation nor CH4 data reported, which also lacks CO2 data.
L39-L42 Since either mild AWD or straw return increased N2O, it is difficult to directly conclude they are promising agronomic measures to reduce greenhouse effect.
L36-39 “mild AWD irrigation reduced N uptake by rice in the soil and rice aboveground biomass” This is also difficult to directly see the difference from either Fig. 4 or others. We can see adding either urea or straw increased N from N inputs instead of soil, but the difference between CF and AWD should be better presented.
In addition, the description of results was hard to follow. The authors compared their treatments of CK, S, U, U+S in all their figures and tables, but the main conclusion of this experiment was the effects of mild AWD irrigation, so the comparison between CF and mild AWD was often missing for statistics either in the figures or tables.
Finally, language needs improvement throughout the manuscript. For example, nitrogen can be replaced by N after first-time mentioning.
Minor points:
In Abstract, the description of treatments was missing.
L33 Numbers of percentage increase are needed here
L57 reduce water waste and environmental pollution
L65-67 Possible reasons to explain can be introduced here.

These evidences have significance for monitoring N2O emissions in paddy fields. However, I still have some comments here for the authors to address before it’s ready for publication.
Answer: We thank you for your recognition and praise of our manuscript, and hope that our research can provide valuable reference for other colleagues.
For several places, there are something important missing for the authors to have their conclusions.
For example, in abstract L33-36 “mild AWD reduced GWP by 62.9%”, but there is neither GWP calculation nor CH4 data reported, which also lacks CO2 data.
Answer: We further refined our conclusions and supplemented the CH4 data in the "Supplements". Please see lines 31-36.
L39-L42 Since either mild AWD or straw return increased N2O, it is difficult to directly conclude they are promising agronomic measures to reduce greenhouse effect.

Reviewer #2:
This present work aims to investigate the effects of mild alternate wetting and drying irrigation and rice straw application on N2O emissions in rice cultivation. Your research work is interesting and somewhat innovative with 15N tracer technique, but it is suggested to repair major revision. The followings are the points need to be addressed and considered:
Answer: Thank you for your recognition and praise of our manuscript, and hereby reply to your comments as follows.
- Paper explored the effects of mild AWD irrigation combined with rice straw return on N2O emissions and rice yield through rice pot experiments. The authors should supplement the experimental treatment concisely.
Answer: We supplement the experimental treatments. Please see lines 27-32, 113-117.
- In this study, compared with continuous flooding (CF) irrigation, mild AWD irrigation increased cumulative N2O emissions, with an average increase of 28.8%. In addition, adding rice straw to mild AWD irrigation further stimulated N2O emissions. Compared with CF irrigation, mild AWD irrigation increased the yieldscaled N2O emissions, and the addition of rice straw further promoted the yieldscaled N2O emissions under mild AWD irrigation but reduced the global warming potential (GWP) by 62.9%. Under the condition of urea application, compared with CF irrigation, mild AWD irrigation reduced nitrogen uptake by rice in the soil and rice aboveground biomass without reducing rice yield. This is mainly due to a weak problem statement and no clear enough of the extraction of the results. It is recommended to continue in-depth research on this issue.
Answer: We've refined the hypothesis and further refined the Results and Discussion. Please see lines 36-42, 45-48, 102-104, 201-206, 269-272, 283-285, 287-290, 308-312, 351, 376, 427-438.
- In paper, it gives the illusion that introduction and conclusion was related to the effects of mild AWD irrigation, but a detailed comparison and account of mild AWD irrigation is lacking in the results.
Answer: We have added a comparison of CF irrigation and mild AWD irrigation to the results. Please see lines 200-206，282-285，304-310.
- English language should be checked and revised throughout the entire manuscript. For example, the use of abbreviations in article. -L33-36 “mild AWD reduced GWP by 62.9%”, I don't see any description to greenhouse gas excepting the data of supplementary document.
Answer: We improved the language and used abbreviations such as: Nitrogen is replaced by N after first-time mentioning. This manuscript mainly focuses on the impact of AWD irrigation and rice straw returning on N2O emissions, but in order to make the results more referential, relevant data of CH4 are also introduced (Supplements). In addition, we have also included additional clarifications in the manuscript. Please see lines 42, 414, 419-420, 432-433.
-Line62-65: Please add reference.
Answer: We have added the reference. Please see line 69.
-Line117-119: Depth of soil?
Answer: Described here is the thickness of the water layer above the soil.
-Line119-127: Please the description of the test treatment corresponds to Line 110-114.
Answer: We further describe the experimental treatments. This experiment included two irrigation methods, two N application levels, and two rice straw return levels, with three replicates of each combination, for a total of 30 rice pots (urea and straw were labeled with 15N, respectively). Please see lines 113-117.
-L184: It involves three factors.
Answer: Table 2 was analyzed using univariate analysis of variance, and we made annotations. Please see lines 190-192.
-Line312-314: What is the purpose of description that N2O emission is significantly affected by soil temperature?
Answer: This experiment did not explore the influence of temperature on N2O, so this part was deleted. Please see lines 319-320.
-Line396-398: Compared with U, under CF irrigation and mild AWD irrigation, US reduced the uptake of soil-derived nitrogen by rice (the difference was not significant), please reorganize the meaning of the sentence.
Answer: Combined application of urea and rice straw may be more beneficial to the maintenance of soil fertility than single application of urea. We have rephrased this sentence so that the reader can understand it better. Please see lines 402-406.
-The abbreviation in the figures should indicate the full name.
Answer: We explain the abbreviation in each figures and tables.
-Fig. 4: It is suggested to put CF and AWD in the same picture for clearer comparison.
Answer: We put CF and AWD on the same picture. Please see Fig. 4.
