Food Security in China: A Brief View of Rice Production in Recent 20 Years

Round 1

Reviewer 1 Report

-         The abstract requires improvement by adding more explanation regarding the purpose of the study, methods and more results should be present. It should be more informative.

 -        The authors do not make a complete revision of the background of this topic

-        The structure of the paper is well established. The methods are explained in the Introduction part make it confusing. In the introduction, the topic, problem statement, and research gaps should be explained more in detail.

-         the problem and research gaps on that and then present the main contribution of the work.

-       Also, the author should provide a section for literature review and discuss more works related to the given task.

-        The author should provide a good systematic review, explain the limitation of the methods, and then provide the added values of their own proposed correction method

-        In the methodology part the Author didn’t explained the methods of statistical analysis of their work

-        Could the Author represent the data of fertilization (N,P,K), Descripe statistical methods

-         the Author didn’t makes a list of abbreviation in the end of the paper it will be better if its inserted in the text also for table 2 should define in the table or in the header of the table

-        The Authors showed different type of statistical methods but there is no any details in Methodology section could they explain how they anlyse the data

Reviewer 2 Report

Dear Authors,

Detailed notes on the manuscript are as follows:

1) At the end of the "Introduction", clearly state the purpose of the work / research

2) 2.2. Statistical analysis - what kind of correlation did you use (Pearson, Spearman and Kendall?), What program did you use for the analysis (name and version)

3) Figure 2. Total rice planting area… TPA - the data in the chart is not linear; justify why you are using just a linear function (correlation is linear, but coefficient of determination R² applies to every match - consider this)

4) Figure 4. Multicorrelations ... - improve the readability of the diagram (font)

5) Figure 5, 7 - as above

6) Figure 7. Rice production… what do the error bars mean; it is probably a standard error (or 5%), you should also describe the estimation and type of error in 2.2. Statistical analysis

7) Figure 8. Grain yield - as above.

8) Figure 9. Potential - as above.
