nd is responsible for temperature gradients in grains in tall silos. The water or moisture content is an important component of the grain and is the crucial factor affecting the storage of grain. The moisture content is taken into consider- ation during procurement and marketing. The growth and multiplication of insect pests and fungi, the major spoilage organisms of the grains, are dependent on the availablewater in the grain. Grains at the time of arrival to storage site contain dockage whichincludes broken grains, foreign materials, and dust. The presence of dockage is conducivefor the development of insect pests and it impedes effective aeration of the grain in siloor bin (. Grain dust is composed of ne particles of 1- to 1- starch granules, bran akes, or pieces of chaff formed by the abrasion of grains during handling. Beyond certain limits, the dusts form an explosive mixture with air in the presence of spark. Grain has low thermal conductivity and specic heat. Hence, in bulk storage, in the absence of forced air circulation, the heat produced by the metabolic processes of thegrain (and grain pests) does not dissipate readily, resulting in hot spots. Variations ingrain hardness between cereal grains and between cultivars of the same species (.., wheat) have been reported. Grain hardness is an important property, as it can inuence the grains ability to resist damage during handling and insect attack. Bulk density ormass per hectoliter .., weight of given volume of grain including the voids, expressedas pounds (lb)/bushel in the United States and kilogram (kg)/hectoliter in most othercountries, is widely used grain property in commercial contracts. Low bulk densitymeans the grain is infested or infected, or that physiologically immature grains and impuri- ties are present. Grains are hygroscopic and gain or loose water depending on the water vapor present in them and in ambient air to attain equilibrium. Once the equilibrium mois-ture content is reached
