Effect of climate change on burley tobacco crop calendars

In Colombia, tobacco cultivation is an important generator of employment and income for farmers; however it faces different problems as low crop yield compared to other countries; specifically, in the north country, where climatic conditions are less favorable productivity lower than areas country due mechanization. order improve per hectare municipality Ovejas, this research aimed determine water requirements burley under climate variability obtain optimal information calendars. Water were determined using requirement equation. This calculation ethod was programmed Python automate generation maps, developing a tool that allowed detailed analysis unit area week. Based on results obtained, weeks 17 18 year (last week April first May, respectively) proposed planting times, since cycles crops planted period showed precipitation surplus initial phase cultivation, which critical their development. Climate change simulation must be continuously monitored adapt new weather conditions.
