Research article Effect of Moisture Content and Grain Position of rice Panicle on the Tensile Force in Separating Processes of Khao Dawk Mali 105 and Phitsanulok-2 Rice Varieties
Keywords:
Panicle of rice, Tensile force, Rice moisture contentAbstract
The objective of this project was to study the effect of moisture contents and grain positions on the tensile force of rice panicle in separating processes of Khao Dawk Mali 105 and Phitsanulok-2 rice varieties. The moisture contents 6 levels of Khao Dawk Mali 105 were studied; 11.77, 16.38, 23.34, 28.38, 31.76 and 38.36 % w.b. Also, the 5 levels of Phitsanulok-2 were 12.72, 18.57, 26.42, 31.73 and 37.43% w.b. The tensile forces were measured at 3 grain positions of lower, middle and upper of rice panicle. The results showed that the moisture contents and grain positions had statistically significant on the tensile force, but there was no interaction between the moisture contents and positions of rice panicle. The average tensile forces of Khao Dawk Mali 105 and Phitsanulok- 2 were the range of 0.945-1.467 and 1.067-1.641 N, respectively. Moreover, the highest and lowest tensile force was found at the lower and upper, respectively.
