The objective of the current research was to study the applied irrigation scheduling of the potato during two crop cycles (2009 -2009/10) in Cooperative No. 2 in the Yabú Valley of Santa Clara. Also to carry out corrections required in order to establish a scientifically based irrigation program. In the first crop cycle it was proven that the timing of irrigation application and the amount of water applied did not meet the technical criteria but was dependant on the decisions taken by persons with practical experience in relation to this activity and the programming of irrigation characterized by the application of small depths of irrigation which did not moisten below 20 cm of soil depth in a way which the irrigation interfered with the cultural and chemical processes and left the soil with a hydric deficit. In both crops tension meter were placed at 20 and 40 soil depth, taking periodic measurement of humidity and daily measurements of soil and balance water, because of this the number of irrigation was reduce during the second crop cycle.
Key words: Hydric balance; irrigation regime; center pivot.
