Round 1

Reviewer 1 Report

In this research, the effects of different levels of salinity and pathogenic fungi on onion plants have been investigated. The article is well structured to some extent. The important issue is why is this issue being investigated? The importance of doing this must be explained well in the introduction. The following points must be well addressed to prepare the paper for acceptance.

 

-          It is necessary to describe the objectives and innovation of the work in the last paragraph in the introduction section.

-          Specify the number of repetitions for each attribute in M&M section.

-          L80: What is ME? please write in full.

-          In M&M, it was mentioned that different salts were used to create the saline solution, while in the results, only one graph for one solution (it is not clear which solution) is displayed. Please specify how many solutions were prepared and if the effects of all solutions were checked, why only one effect of one solution was added in fig.

-          L240: add this ref.

Reviewer #1: It is necessary to describe the objectives and innovation of the work in the last paragraph in the introduction section.

Response: Added as suggested by the reviewer in the last paragraph of introduction section.

Reviewer #1: Specify the number of repetitions for each attribute in M&M section.

Response: Added as suggested by the reviewer in the statistical analysis under M&M section.

Reviewer #1: What is ME? please write in full.

Response: Added as suggested by the reviewer in the M&M section.

Reviewer #1: In M&M, it was mentioned that different salts were used to create the saline solution, while in the results, only one graph for one solution (it is not clear which solution) is displayed. Please specify how many solutions were prepared and if the effects of all solutions were checked, why only one effect of one solution was added in fig.

Response: After successive irrigations of the prepared solution, the salt accumulation in the soil was approached to equilibrium concentration through evaporation by leaving the salt behind in the soil. That’s the reason we added all the ingredients to make saline solution.

Reviewer 2 Report

This research article entitled: “Impact of various salinity levels and Fusarium oxysporum as stress factors on morpho- physiological and yield attributes of onion” investigated the role of Fusarium oxysporum as stress factor of salinity mediated the morpho- physiological and yield attributes in onion crop. The overall contents discussed in this research article are reasonable and sound. However, there are a few suggestions needed to incorporate to improve the quality of this manuscript. I, therefore, suggest major revision for this manuscript.

General comment:

Similar type of experiment has already been done in previous studies (DOI: 10.1007/s12298-018-0570-z) and (https://doi.org/10.1016/j.pmpp.2021.101602); so authors are advised to improve the novelty of this manuscript.


Specific Comments:

1. In the abstract, please mention treatments of study which are missing.

2. Authors are advised to improve the quality of abstract section, please highlight the scientific value-added to your paper in your abstract. Moreover, abstracts should clearly state the essence of the problem you are addressing, what you did and what you found and recommend.

3. The introduction section is too small and not convincing, in the introduction, you need to connect the state of the art to your paper goals. Please follow the literature review by a clear and concise state of the art analysis. This should clearly show the knowledge gaps identified and link them to your paper goals. Please reason both the novelty and the relevance of your paper goals. Clearly discuss what the previous studies that you are referring to. What are the Research Gaps/Contributions? Please note that the paper may not be considered further without a clear research gap and novelty of the study.

4. The introduction section is abrupt and background information are scattered. It lacks the systematic layering and connectivity between the sentences as well as paragraphs. What were the key objectives of this study? What was the hypothesis of manuscript?

5. In materials and methods statistical section, add some sentences about ANOVA process and level of significance etc.

6. In result section, quality of figures should be uniform (and should be improved further by using graphpad or graphprism) in format, letter font and size should be the same as the remaining manuscript body. Furthermore, data presented in table 2 should be converted into figure.

7. Moreover, authors are advised to add precision correlation and principal component analysis in results section In your discussion section, please link your empirical results with a broader and deeper literature review.

8. One way of improving Discussion is to avoid repetition of results in this part. Discussion is very shallow and needs in depth discussion with the recent literature published. In discussion, there is a lack of mechanistic approach.

9. The conclusion is generic and fails to provide any improvement in the existing knowledge base. The conclusions can still be improved by providing an analysis of where the current work on adsorbents is focused, what are the remaining gaps in literature and where more research should be conducted. It is recommended to use quantitative reasoning comparing with appropriate benchmarks, especially those stemming from previous work. Limitations in the suggested approach should be discussed in the conclusions section. Please add future work as well.

10. The language of this manuscript should be edited by a professional edition.

11. The reference of the article needs to be checked, revised and formatted.

Moderate editing of English language

Reviewer 3 Report

The paper, entitled Impact of various salinity levels and Fusarium oxysporum as stress factors on morpho-physiological and yield attributes of onion, describes how various salinity stress under the pathogen pressure Influence the anatomy and physiology of onion. The article is completely silent on how to tackle these concerns in to the onion crop. Though, it contains some interesting results and can be published if the following recommendation is addressed properly.

The article has been written very weakly and contains various grammatical and scientific mistakes. Some sentences were difficult to understand.

 

Minor revision

Every abbreviation must be written completely for the first time such as PR protein

in vitro italic invivo

Major

It is obvious that salt stress negatively impacts plant health and productivity and the results claimed it here, interestingly, the author(s) inoculated soil-borne pathogens and multiplied the stress which consequently worsen the condition of plant and significantly impacted the whole parameters. What are the objectives of applying them? Though apparently, the article doesn’t portray any positive influence on onion morphology, physiology and yield?  

If the article just wanted to address that the combination of salinity levels and tested fungal pathogen exhibited more damage on growth and production of onion as compared to sole stress, then its okay and it has interesting results, though the article lack of solution

Abstract. ,

The abstract needs to be rewritten following the following steps:

M&M, results, and conclusion.

Lacks the stress level of salt stress, inoculation of Fusarium, pots experiment, etc

 potentially hazardous factors or factors?

Why Keywords: Basal rot? The title and abstract lack it, and it is not highlighted though.

 

 Fungal biomass, in vitro condition, was increased at 2-8 dS m-1 salinity levels >>????

Level of salinity stress?

Introduction

The last paragraph of the introduction needs to write the aims explicitly and comprehensively.

Preparation of saline soil. This heading could be improved by rearranging the materials such as onion seedlings sowing, salinity stress and Fusarium suspension preparation and inoculation.

Plant growth attributes (length and weight) and bulb growth parameters (weight 137 and diameter) were noted after 60 days of inoculation of what? pathogen or salt stress?

How many replicates were used in each treatment?

Results

The figures are made via Excel sheet, it can be improved by using Origin software etc

The salinity stress in combination with the pathogen significantly impacted the bulb biomass and reduced its biomass, what the article addresses in this case?  The same case was observed in 3.3 Impact of stress conditions on physiological attributes of onion
