[online]. 2018, vol.6, n.16, pp.15-29.  Epub 04-Ago-2020. ISSN 2007-8064.  https://doi.org/10.22201/enesl.20078064e.2018.16.63206.

Specialized literature does not delve into economic impacts of chill hours on agricultural production yields. The objective of this article is to evaluate economic impacts of chill hours on wheat in four producing regions: Cajeme, Navojoa, Hermosillo and Guaymas. The methodology consisted in a correlation exercise between crop yields and chill hour averages for each region; subsequently, a benefit-cost analysis was carried out based on the construction of three chill hour scenarios. In the results, the obtained coefficient r was 0.80, which confirms a positive relationship between chill hours and crop yield; the benefit-cost analysis shows that in Hermosillo, greater economic gains are obtained per hectare. The findings of this work lie in its importance to the economic sphere, providing information of chill hour impact on crop profitability.
