Effect of Elevated Air Temperature on the Growth and Yield of Paddy Rice

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

Authors have studied the growth and yield parameters of rice in response to changing air temperature (from ambient temperature to a temperature raised to 3°C) in two different years. Authors have written the manuscript well. Minor corrections are needed to be included because it can be accepted for publication. Please find the minor corrections or suggestions mentioned below:

 

1.     Please elaborate SPAD

2.     What was the variety of rice used. Please provide the information.

3.     In the methods section, please describe clearly at what stage the rice seedlings were transplanted. It will not be clear to the readers if only the dates are provided.

4.     Line 269: Instead of writing as “plant height growth”, just write as plant height

5.     Line 319: Please check the spelling of plant

6.     Figure 5 can be improved to distinguish the data from two years more clearly.

7.     Authors have to check the tense of the manuscript carefully.

 

Comments on the Quality of English Language

Manuscript needs minor english language editing especially the tense used in the manuscript.

Reviewer 2 Report

Comments and Suggestions for Authors

Dear Editors and Authors,

 

I read with interest the manuscript entitled “Growth and Yield Responses of Paddy Rice to Elevated Air Temperature”. The purpose of this study is to monitor growth, development, and physiological responses to high temperature conditions on paddy rice and to assess their combined effects on yield. The subject of the article is important and has great relevance for the scientific environment of the study area. Therefore, the manuscript needs some adjustments so that it can then be forwarded to the publication process. The manuscript has the potential for publication in this journal Agronomy and needs the following adjustments:

 

TITLE

 

- Remove the term “response”.

 

ABSTRACT

 

- The objective must be the same as mentioned in the Introduction.

- Before describing the results, it is necessary to mention the treatments used in the research.

- Replace the keywords that are present in the title.

 

INTRODUCTION

 

- In the first paragraph and others, there is important information that needs to be referenced. There is information for example “Rice is one of the three main food crops and the second largest food source in the world, after wheat, satisfying around 80% of the dietary caloric needs of more than half of the world's population. It is a critical crop in the context of food security, but it is vulnerable to high temperatures and presents large yield fluctuations”, which must be referenced.

- At the beginning of the second paragraph, “studies” are mentioned and only one study is mentioned. Insert more.

- There was no need to include a justification for the study, before the objectives. If possible, also insert the hypotheses for the work.

 

MATERIAL AND METHODS

 

- Remove the horizontal and vertical lines inside the figures with climate data.

- “NDVI is widely used to represent the amount of vegetation, greenness and health of vegetation and is related to vegetation structure and photosynthetic capacity [29]”. This information is a literature review. It is not part of the Material and Methods section.

- In gas exchange analyses, did the number of leaves vary from 3 to 7? Why wasn't there a standardized number of leaves for all plants?

- Why was the assessment time between 9 am and 3 pm? This interval is very distant and can harm the analysis and interpretation of the data.

 

RESULTS AND DISCUSSION

 

- Suggestion for the entire text: There is no need to mention that there was linear behavior... Linear regression models were not tested for this statement.

- In the paragraph before Figure 4, you do not need to underline the text. Information about non-significance is irrelevant and does not need to be detailed or discussed in the text. To review.

- Some variables need to be discussed in more detail. Review this section.

-

CONCLUSION

 

- The conclusion is very big. Reduce. Detail only the main information from your results and end with a general conclusion.

Comments and Suggestions for Authors

The authors of the manuscript ‘Growth and Yield Responses of Paddy Rice to Elevated Air Temperature’ studied a temperature gradient 25 field chamber (TGFC) with a gradient from the ambient air temperature (AT) to 3℃ above the AT 26 (AT+3℃) was used to identify changes to growth, maturity, and senescence in paddy rice through- 27 out the growing season. The study looks exciting and suitable for an agronomy journal. Please make some minor revisions before acceptance.

L 28, SPAD or chlorophyll?

Check space in (AT+3℃)

L 94, 110, You do not need to write abbreviations repeatedly.

Please check the whole MS.

I think the Introduction is concise.

Check Figure 2 legends, A-D and B-E.  

Please check references in material and methods; whose method did you follow?

I think add some references.

L 334-338, please check

Figure 4 B and D use zig-zag lines for non-significant

L 272, (e.g., [10,23]), please check

In the discussion, please compare your results with other published results.
