Three popular paddy varieties in Sri Lanka, BG358, BG360 and BW367, were experimented in order to determine the important physical properties and water absorption capacities. Axial dimensions (length, width, and thickness), 1000 grain mass, geometrical mean diameter, surface area, volume, sphericity and aspect ratio were determined as the physical properties of paddy varieties. According to the research outcome, most of physicalproperties were significantly different (p<0.05) among the varieties while some similarities (p>0.05) were also observed. To investigate the water absorption capacity of different paddy varieties in terms of moisture gain, the paddy varieties were immersed in hot water at 70 C for 5 hours. Samples were drawn from respective paddy variety for every 30minutes in order to measure the moisture absorption. According to the results, during the initial stage of soaking, all paddy varieties illustrated rapid moisture increment. Afterward the rate of moisture in...
