Technical Abstract: The BIOTIC or TTT method of irrigation scheduling is based upon continuous measurements of canopy temperature and has been evaluated for a number of crops in a number of environments over a 20-year period. Its primary advantages are its low cost and ease of implementation. It has not been extensively evaluated under deficit irrigation conditions particularly in comparison with traditional ET-based irrigation scheduling protocols. In this study we compared the seasonal pattern of BIOTIC irrigation in cotton with a recursive method of crop ET based on the Penman-Monteith.
