Author Response

Dear Reviewer 1.

First of all, we would like to thank the suggestions made that help on improving the quality of the manuscript.

Discussion were added as required (lines 109-116, 123-138), actually replacing some statements that were overlaying the data presentation on tables. English was reviewed as well.

Best regards,

Reviewer 2 Report

The topic of the manuscript is interesting. However tehcniques used for analysis are not up to dated. Many researchers have worked on Energy use in agiruclture and estimation/analysis of energy is extensively developed. In this manuscrip author have relied on some basic analysis such as, Energy Balance, Energy Return on Invesment, and Energy merger. Author (s) can use some advance and sophisticated tool for energy/efficiecny analysis.

Dear Reviewer 2.

First of all, we would like to thank the suggestions made that help on improving the quality of the manuscript.

We added on Introduction some remarks about the technique adopted (lines 47-50). We do agree that there are other ways to approach energy efficiency, but for scenarios of “off season” cropping system, there is little information about environmental footprints, this was the reason of choosing the most traditional approach and indicators on this first report from a broader project.

Discussion were added as required (lines 109-116, 123-138), actually replacing some statements that were overlaying the data presentation on tables. English was reviewed as well.

Round 2

Reviewer 2 Report

The quality of the article could have improved by adopting an advanced energy efficiency analysis method. I hope in future you will explore and use those methods.
