Storage behaviour of pigeonpea grains prepared from untreated grains was studied for eight months under various storage conditions. Grain samples were stored in different packaging materials i.e. polythene. poiylined and jute bags at 9% and 12% initial moisture content. Effect of ethylene di bromide treatment on moisture adsorption-desorption behaviour was also investigated. Moisture content of grains stored in jute bags at 9% and 12% initial moisture content was the highest followed by polylined and jute bags. Ethylene di bromide treatment did not effect the moisture content of grain during storage. Polynomial models of second and third order could predict the moisture content of pigeonpea grain
