“…At higher moisture levels, bulk density was higher for proso millet followed by barnyard millet, fi nger millet, kodo millet, foxtail millet and little millet. A similar relationship was reported by Shepherd and Bhardwaj (1986) and Dutta et al (1988) for pigeon pea and gram, respectively. However, Suthar and Das (1996) found that the bulk density increased linearly with grain moisture increase for karingada seeds.…”

“…Thermal properties including specifi c heat, thermal conductivity and thermal diffusivity were determined by Subramanian and Viswanathan (2003) for minor millet grains and fl ours. Also many researchers have determined the bulk density and friction coeffi cients for pigeon pea (Shepherd and Bhardwaj 1986), gram (Dutta et al 1988), soybean (Sreenarayanan et al 1988), green gram (Nimkar and Chattopadhyaya 2001), chick pea seeds (Konak et al 2002) and rapeseed (Calisir et al 2005). Manimehalai and Viswanathan (2006) determined the coeffi cient of internal friction for cassava fl our and fuzzy cottonseeds.…”

Physical properties including 1000 kernel weight, bulk density, true density, porosity, angle of repose, coeffi cient of static friction, coeffi cient of internal friction and grain hardness were determined for foxtail millet, little millet, kodo millet, common millet, barnyard millet and fi nger millet in the moisture content range of 11.1 to 25% db. Thousand kernel weight increased from 2.3 to 6.1 g and angle of repose increased from 25.0 to 38.2 o . Bulk density decreased from 868.1 to 477.1 kg/m 3 and true density from 1988.7 to 884.4 kg/m 3 for all minor millets when observed in the moisture range of 11.1 to 25%. Porosity decreased from 63.7 to 32.5%. Coeffi cient of static friction of minor millets against mild steel surface increased from 0.253 to 0.728 and coeffi cient of internal friction was in the range of 1.217 and 1.964 in the moisture range studied. Grain hardness decreased from 30.7 to 12.4 for all minor millets when moisture content was increased from 11.1 to 25% db.

“…The averages of the replicated values are usually reported. Bulk and seed density: A method similar to that reported by Shephered and Bhardwaj (1986) can be used to determine the bulk density at each moisture level: a 180 ml cylinder was filled continuously from a height of about 15 cm. Tapping during filling was done to obtain uniform packing and to minimize the wall effect, if any.…”

“…The filled sample was weighed and the bulk density of the material filling the cylinder was computed (Shephered and Bhardwaj, 1986;Deshpande and Ali, 1988;Mohsenin, 1970). The seed density of the grain can be determined by the liquid displacement method to determine the seed volume similar to that reported (Shephered and Bhardwaj, 1986;Deshpande and Ali, 1988). Sphericity and porosity: According to Mohsenin (1970), sphericity ф, was calculated using the formula.…”

INTRODUCTIONIn India, grain production has been steadily increasing, due to advancement in production technology, but improper storage results, in high losses in grains. Post-harvest losses in India amounted to 12 to 16 million metric tons of food grains each year, which is an amount that could feed one-third of India's poor population (World Bank Report, 1999). The monetary value of these losses amounts to, more than Rs 50,000 corers per year (Singh, 2010).During storage, both quantitative and qualitative losses occur due to insects, rodents and micro-organisms. Grain storage plays an important role, in preventing losses which are caused, mainly due to beetles, moths, weevils and rodents (Kartikeyan et al, 2009). It is estimated that, 60-70% of food grain produced in the country is stored at home level, in indigenous storage structures. To reduce the storage losses of grains during storage period, modern storage structures and safe and scientific storage techniques are being used, which includes warehouses, cold storages, controlled atmospheric storage, modified atmospheric packaging, spraying the chemicals, controlled atmospheric grain storages, etc.Modified atmospheres (MA) or controlled atmospheres (CA) offer an alternative to the use of conventional residue producing chemical fumigants for controlling insect pests attacking stored grain, oilseeds, processed commodities, and some packaged foods. These atmospheres also prevent fungal growth and maintain product quality. The MA may be achieved in several ways by adding gaseous or solid CO2, by adding a gas of low O2content (e.g., pure N2) or by allowing metabolic processes within an airtight storage to remove O2, usually with associated release of CO2. They are collectively known as modified atmospheres '(Banks and Fields, 1995).Modified atmosphere storage of seeds is a suitable alternative to the use of chemical fumigants and contact
