Reviewer 2 Report
Comments and Suggestions for AuthorsL 20-21 I propose to also include rainfall, which is becoming increasingly irregular due to climate change
L 220-222 It would be interesting if you had also installed soil moisture sensors also to deficit irrigation plots, and monitor if soil moisture dropped bellow readily available water level (ETc=EToXKcXKs).
L 456-463 I think that it would be useful to refer at the discussion the probability of application of ET data services like CIMIS and DSS for irrigation management, mainly those that do not need sensors to be installed at the field like Manna, IrriSAT, IRMA_SYS or other relevant. Pilot fileds can be use to adapt such systems to local level. These could promote irrigation water use efficiency even when surface irrigation is applied and build consiousness regarding efficient irrigation water management which will be an add-on when resources to install micro-irrigation systems are available.

Reviewer 3 Report
Comments and Suggestions for AuthorsReview of the article entitled "Transformation of terraces with irrigation systems: profitability and water savings in potato crop (Solanum tuberosum L.)".
The paper presents a study conducted in the mountainous areas of southern Peru, aimed at evaluating the water and economic efficiency of the combined use of drip irrigation systems and deficit irrigation techniques on potato terraces.
With some revisions, the study has the potential to be published in the water so in my opinion the work can be accepted after minor revision.
General considerations:
The study provides useful information for local farmers, showing that drip irrigation can increase the profitability of terrace crops, although it requires greater initial investment.
The description of the study area is detailed, but could be integrated with a map or satellite image to help readers better visualize the geographical context.
The discussion of the results could be more in-depth, comparing the data obtained with similar studies conducted in other regions. There are no considerations about the limitations of the study, such as the relatively short duration of the experiment (only one growing season) and the need to validate the results on longer time scales.

Line 87-89 and lines 104-106 when referring to water use efficiency and Economically Optimal Irrigation Depth, it may be useful to cite this article: Autovino D., Provenzano G., Monserrat J., Cots L., Barragán J. (2016). Determining Optimal Seasonal Irrigation Depth Based on Field Irrigation Uniformity and Economic Evaluations: Application for Onion Crop. Journal of Irrigation and Drainage Engineering, 142(10). https://doi.org/10.1061/(ASCE)IR.1943-4774.0001048
Line 156 the number 2 of m2 must be at the apex
Line 160 it should be specified why the soil characterization was done only for the depth of 30 cm
Line 178 rather than the “conduction pipes” I would prefer to use the term “main line”
Line 179-179 rather than “distribution pipes” I would prefer to use the term “sub main line” or “manifold”
Table A1 the values ​​of field capacity and permanent wilting point are missing. The term Worth is generally used to indicate the monetary value of something. I think it would be appropriate for the authors to replace the word “Worth” with “Value/class” so as to also include the textural classification of the soil.

Reviewer 1 Report
Comments and Suggestions for AuthorsIn the previous review, the authors have fulfilled almost all of them. However, it is still not very clear for the reader of some graphics. If possible, they should be made visible at a higher resolution or in a different way.
Comments on the Quality of English LanguageIt could be checked lastly in terms of Jorunal rules
