Peer review report 2 On “Evaluation of the impact of climatic trends and variability in rice-wheat system productivity using Cropping System Model DSSAT over the Indo-Gangetic Plains of India”
Original Submission Recommendation: Accept Comments to Author: The rationale of the present work is to investigate factors that could affect the yields of rice and wheat crops, which ensure food security for major population in the concerned regions of India. Main fact is the lack of significant precipitation rate for recent years. Hence, zonal gradient in decrease of rice yield would have other causes. Instead, scenario of reduction in sunshine hours seems to be at the root of the observed trend. The authors should precise the reason for that, meaning ratio of increased cloudiness or air pollution. It would be expected there-

fore a decrease in minimum temperature but reverse scenario occurs, which is not straightforward. The wheat crop seems to follow an opposite trajectory to rice crop but probably because it comes at a different season where stress factors are less significant. Also to believe that methods for wheat growth may better adapt to changing climate scenario. All the scenarios are well supported by crop gowth simulation models. For this reason, I will recommend publication of the study with minor revisions, provided the authors could answer to the aforementioned concerns. Anonymous Available online 6 August 2015
