. Four clones of rubber trees seed were considered, GT 1, NIG 800, NIG 900, and RRIM 707. The Avery Dension (6403/A/32128) model of brinell hardness tester with capacity of 3000 kaf was used for Brinell hardness test. Shear strength testing machine was used for shearing strength test. GT 1 clone has hardness number of 79 and Shearing Strength of 0.1468N. NIG 800 clone has hardness number of 71.064 and Shearing Strength of 0.1280N. NIG 900 clone has hardness number of 70.284 and Shearing Strength of 0.0155N. RRIM 707 clone hardness number of 68.21 and Shearing Strength of 0.15976 N. The hardness/compressive strength and shearing strength were determined at 14.6 % moisture content. From the data obtained for mechanical properties of rubber seed, it was established that, they are useful in design of post harvest handling and processing operations.&picture=http://www.aascit.org/aascit/decorators/img/journal/902.jpg)

Rubber seed produces non-edible oil that has the potential to replace/substitute for edible oils such as palm oil, coconut oil, etc. as a raw material for biodiesel during periods of high food sector demand. Therefore, this study determined the mechanical properties of rubber seed (compressive strength and shearing strength). Four clones of rubber trees seed were considered, GT 1, NIG 800, NIG 900, and RRIM 707. The Avery Dension (6403/A/32128) model of brinell hardness tester with capacity of 3000 kaf was used for Brinell hardness test. Shear strength testing machine was used for shearing strength test. GT 1 clone has hardness number of 79 and Shearing Strength of 0.1468N. NIG 800 clone has hardness number of 71.064 and Shearing Strength of 0.1280N. NIG 900 clone has hardness number of 70.284 and Shearing Strength of 0.0155N. RRIM 707 clone hardness number of 68.21 and Shearing Strength of 0.15976 N. The hardness/compressive strength and shearing strength were determined at 14.6 % moisture content. From the data obtained for mechanical properties of rubber seed, it was established that, they are useful in design of post harvest handling and processing operations.
