Comments and Suggestions for Authors

The manuscript on "Timing Matters: The Impact of Sowing Dates on Photosynthetic Traits and Biomass Accumulation in Hybrid Winter Wheat" reports important results with respect to the effect of sowing dates on the performance of wheat. The following are suggestions for the improvement.

In the Abstract the use of word good seeds should be defined (what it mean -which are the factors to categorize the seed as good).

How much yield reduction observed with delayed sowing (D3) should be given and the justification for higher yield with D1 and lower yield under D3 should be clearly reflected.

The detailed characteristics of the varieties tested should be mentioned in the materials and methods.

Details of the methodology followed for recording the yield should be described.

Principal Component Analysis (PCA) may be employed to give a clear picture of association of different characteristics with grain yield of wheat.

Discussion should also deal with association/interaction among different growth and development characters of wheat under three dates of sowing of wheat.

Conclusion should give some direction for future line of work.

Reviewer 3 Report

Comments and Suggestions for Authors

The study by Zhang et al. examines the sowing dates of two wheat varieties during two growing seasons and their effects on physiological and agronomic traits. The authors have clearly processed, presented, and explained the obtained data. Technical corrections, which are indicated in the manuscript, need to be corrected.
