Water stress in potato, corn and pea crops.

The evapotranspiration of potato, corn and pea crops in the central region of Boyacá (Colombia) is analyzed under standard conditions and under hydric stress to determine water requirements and optimal planting calendars according to water balances. The study included the collection and purification of information that has a greater impact on these phenomena such as climatological variables, crop physiology and soil types; Mathematical models that describe evapotranspiration and water needs were designed and adjusted, which were implemented computationally through the simulation of all possible crops under study in the analysis period from 1967 to 2019. As results, critical periods were determined and optimal planting dates were established for each crop. [ABSTRACT FROM AUTHOR]
