Abstract. Triticale is being studied as a substitute for corn in animal feed and as a forage crop for Florida. Storage of triticale seed is difficult in Florida’s climate, and more information about equilibrium moisture content (EMC) relationships of triticale is needed to develop improved storage methods. Therefore, the research objective was to measure the EMC for triticale seed and to determine the best fit equation representing the EMC. This study measured the EMC of triticale at three different temperatures 5, 23, and 35°C using a static method using six desiccation jars with six different salt concentrations. These salts provided relative humidities (RH’s), of 11, 23, 33, 58, 75, and 84% at 25°C. An average of ten weeks was required to reach equilibrium when the initial moisture content (MC) of the seed was 13% (wet basis). The results of this experiment were used to develop a prediction algorithm representing the relationship between RH and EMC with coefficient of determination (R2) equal to 0.99. It was also found that the Modified Henderson equation represents this relationship accurately. Overall, this result will aid the development and improvement of drying and storage methods for triticale seed.
