Abstract

The growing trend of population and limitation of production resources, have led to make more attempts for increasing the crops yield. In present study the effects of temperature, precipitation and agricultural inputs (seed, fertilizer, pesticides and machineries) on cotton yield have been evaluated during the period of 2002-2011 in selected provinces of Iran. Required weather data were collected from Iran Meteorological Organization. Data were checked for normality and used for estimations by fixed effect data panel method. The results showed temperature increase during the growing season have negative effect on cotton yield. Such that, the yield would decrease 38 percent per one degree temperature rise. Besides, it was found that the cotton production trend has been decreasing in study regions. Considering the increasing trend of temperature and limitation of water resources, proper measures should be adopted for further adaption.
