Title
The effect of weather variables on wheat yield (Triticum aestivum L.) in Tehran and Alborz provinces
Authors
Abstract
Climate change is recognized as one of the most challenging aspects of today's agriculture, and it is gaining momentum in research field worldwide. This survey was conducted to evaluate the effects of weather variability on irrigated wheat in Tehran (Tehran, Ray and Firouzkouh counties) and Alborz provinces. Data included grain yield and weather variables (maximum, minimum and daily mean temperatures) of the study sites bracketing 1990 and 2010 except for Firouzkouh which covered 13 year period bracketing 1997 and 2010. Results on monthly basis indicated that Karaj and Ray counties showed the highest relationship between yield and weather variables in October and February, while in Tehran it was revealed that wheat yield had high association with weather conditions of June and February. Similar relationship was observed between February and January weather factors with wheat yield in Firouzkouh. In conclusion, February had the highest association with grain yield in terms of weather variables studied.
