PONE-D-21-30561Growth and Trend Analysis of Area, Production and Yield of Rice: A scenario of rice security in BangladeshPLOS ONE

Dear Dr. Al Mamun,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by Nov 25 2021 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io.

Reviewer #1: The rice production of Bangadesh is the third in the world.To identify the factor underlying the trend in rice production of Bangadesh is important to carry out the region-wise plant and relative policy strategies to o ensure rice security of Bangladesh. From 1969-70 to 2019-20, rice production of Boro rice is increasing at 0.97% per year, mainly dueing to the development of two Boro mega varieties. Meanwhile, High yielding variety adoption rate of Aus and Aman has increased to 72% and 73.5%, respectively. The findings is important for rice production in Bangadesh. However, several aspects mar the overall understanding and need to be addressed:

1.The solution of Figure1, Figre4, Figure6, Figure8, Figure9 is too low to read clearly. It is necessary to provide high solution of the above Figure.

2.For Figure3(a), Figure11, Table2, Table3 and Table4, two-way-ANOVA is needed to analyze the data. A 2-way-ANOVA is a two factorial analysis (here region/season and period as the 2 parameters). With suitable post-hoc test, this should be marked with distinct statistical groups (typically different alphabets) to allow one to see if there was difference in region/season and also between periods.

3.The coefficient of variation for different regions is needed in the Table 4 to support the result “but region to region yield variations were very high” (Line 337 to 338).

4.In Figure12, for Aman and Boro，most region have positive production growth rate. But, for Mymensingh, Bogura, Dinajpur, Rangpur, Dhaka and Faridpur have negative production growth rate where the other regions have positive production growth rate. 5.More detailed discussion is needed to illustrate this phenomenon.

Minor revision: 2019-202 (Line201) should be revised as “2019-20”.
