Abstract

The study was carried out to determine the longitudinal ultimate tensile strength (uprooting force) of the roots of sorghum bicolor, an important staple food in the semi-arid to arid parts of the world. The mean ultimate tensile strength of the sorghum roots was 893N. Different varieties namely Prime silo, Mundy, Mr-Buster-Thiram and Birdgo had varying ultimate root tensile strengths. The ultimate tensile strength of variety Prime silo of 1323N was significantly higher than those of Birdgo and Buster-Thiram at 511N and 725N respectively. Mundy at 1013 N was not significantly different from Prime-Silo or Mr Buster Thiram, however it was significantly stronger than Birdgo. The soil moisture condition has no effect in the ultimate tensile strength of the sorghum roots.
