Round 1

Reviewer 1 Report

In the manuscript the authors presented an important point, although the manuscript has some drawbacks.

Main remarks:

1. Materials - the results of the ADF test for the stationarity of the series are missing.

- not "zloty" but PLN,

2. Conclusions - very short. In your conclusions, please also answer the following questions:
• what are the directions for the future?
• what are the research gaps?
• what is new to this manuscript?

3. Discussion - too short discussion. Not critical.

4. References - a short list of literature.

Reviewer 2 Report

Dear authors, 

I am glad I have this opportunity to review your manuscript. Based on its reading I have the following notes/comments: 
Introduction - the last paragraph should be dedicated to the aim definition and the structure describtion (introduce readers how you wanna continue);
Time period - too short time scope of the research; the prices of agricultural products are characterized by high volatility, therefore it is worth considering a longer time frame in such analyzes 
Results and Discussion - there is no comparison of the obtained research results with the research presented in other scientific publications; the research results are not innovative 
References - I found a lot of Polish literature; look for other foreign sources where similar methods are used and compare the obtained results.
I personally consider your manuscript as a very interesting one. Many methods/formulas are used. 
I wish you all the best with this manuscript and other ones in the future.
