Great, just a few comments:

• What's your working title?
• In the introduction, I would also include a section on the relationship between irrigation practices and nitrogen efficiency/leaching. I think the introduction to SWAP-WOFOST can be moved to the methods.
• Combine sections 2.2 and 2.3 and call it "SWAP-WOFOST model parameterization and calibration"
• In the results, I would have 3.2 be yield results and 3.3 be nitrogen leaching results
• Remove 3.3 and instead have it be one of the sections of the discussion.
• Have section 4 be the discussion and break it down into implications for management, limitations and assumptions of current study, and areas for additional research.

We also need to think through the best way to present the results. Generally, if you have a situation where you've got multiple figures that are basically the same thing but a different scenario (e.g., Figures 5-9), that's information that is better presented in a table. We'll want to include at least some of those figures, but not necessarily all (or some might be in the supplementary material). But let's take a look at the results once we're satisfied with them and determine the best way to preset them.

Thank you, Dr. Shortridge. I have updated the outline accordingly and added the working title. I do think that there should be a better way to present the results instead of including all the figures.

@julieshortridge Hi Dr. Shortridge, I have updated the outline, If you could have a look sometime and provide feedback, that would be great!

Good work Suman, I think this is coming together nicely. A few comments:

• Title is a little lengthy. I'd suggest: "Field-scale Benefits of Irrigation and Nitrogen Management Strategies in Changing Humid Climates Using SWAP-WOFOST Model"
• Novel contribution of this study - I think you can also mention the consideration of changing rainfall patterns, rather than just total amounts, as something novel.
• Change section 2.5 to "Analysis of Yield, Nitrogen Transport, and Water Use"
• Make Section 3 Results, and then a separate Discusion section as Section 4.
• Change 3.1 to "SWAP calibration results".
• I still think we'll want to think through the best way to present your results in terms of yield, N uptake/leaching, and water use. I think we'll need the tables showing average across the simulations and significant differences between them (possibly by including the average value in the table and then using a/b/c superscripts to denote significantly different groups). We'll also want at least some figures showing year-by-year results, but we'll have to think about which to include. One strategy would be to include a figure showing the most compelling differences, and then put the remaining year-by-year figures in the supplementary material.
• Section 4 should be a seperate discussion section that includes 1) discussion of your results relative to previous studies, 2) limitations and areas for additional research, and 3) practical implications for agricultural water management.

Thank you Dr. Shortridge. These changes sounds reasonable to me. I have updated the outline accordingly.
