Economic Analysis of Azospirillum brasilense Inoculation Associated with Enhanced-Efficiency Nitrogen Fertilizers in Corn Production in the Brazilian Amazon
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsDear authors of the manuscript Azospirillum brasilense associated with nitrogen fertilizers with improved efficiency in corn production in the Brazilian Amazon, I would like to thank you for sending your work for review to the journal. I want to mention that you have several areas of opportunity to improve your manuscript, which I describe below:
1. On line 39, the symbol "-1" must be placed in superscript
2. The introduction lacks important information that can support the study that you carried out in the sense that you do not mention if there are other studies where other bacteria have been used for nitrogen fixation in fertilizers or applications of the bacteria.
3. The results can be complemented with a simple ANOLVA analysis to know which of the economic variables have a greater impact on the economic analysis they carried out.
4. The conclusion must be described since the way it is presented cannot be considered a conclusion and take into account the main objective of the study.
Good luck

Ok, it was done and is included in the attached file.

No correction was made, despite the suggestion being very interesting.
The authors justify that the data shown are estimated values, if statistics were applied, all treatments would show the same statistical difference for all variables.
Another detail, as these are financial values, farmers are not looking for statistical differences, but rather financial superiority, despite the statistics showing the difference between treatments, corn producers aim for greater financial profit.
4. The conclusion must be described since the way it is presented cannot be considered a conclusion and take into account the main objective of the study.
Ok, it was done and is included in the attached file.

Reviewer 2 Report
Comments and Suggestions for AuthorsThe article is devoted to the economic analysis of the inoculation of Azospirillum brasilense under different options of nitrogen-containing fertilizers for the corn crop grown in the Brazilian Amazon.
The research topic is important and relevant. There are technical notes to the reviewed article. In particular, the word “inoculation” should be reflected in the title for a clear understanding of the role of the bacterium used.
Line 13. Please write Azospirillum brasilense (A. brasilense)
Lines 16, 19 – Abbreviated name should be written A. brasilense
Line 17 – NBPT – decipher (and in the text of the article at the first mention as well)
Line 40 – kg ha-1 write down kg ha-1
Line 49 - Write Azospirillum brasilense (A. brasilense), and then in the text write the abbreviated name A. brasilense
Lines 63-65 – decode conventional notation. If the concentration of cations is indicated, then write, for example, [Ca2+] = .... etc. K = 121.3 mg dm-3 is the concentration of potassium ions? Then you should write [K+] = 121.3 mg dm-3.
Line 68, Table 1 – the name of the bacteria should be written in italics
Line 71 – the source of the Azospirillum brasilense strains used, the collection, should be indicated.
Line 72 - 2×108 write 2×108 CFU mL-1 – specify not mL, but mL-1
Line 105 – close the parenthesis
Lines 58-106 – The Materials and Methods section should be rewritten to include subsections
Table 1 – B1.2 – B1.5 – which stands for de N. It should also be deciphered as HM. Make spaces between numbers and units of measurement (50kg...200kg). It is similar in Table 2.
Table 2, Table 3 (marked as Table 1) – in the notes, decipher the notations
Line 149 – The number of the table should be 3. You should also write the name of the table.
After making corrections, the article can be published.
