Abstract
Abstract. Sorghum has a higher protein nutrient content (11%) than rice (6.8%) per 100 grams of ingredients. However the development and yield of sorghum is still low compared to other food crops. One of the causes of low sorghum production yields is because seed deteriorate rapidly. The deterioration of sorghum seeds during storage signals a low seed vigor. So it is necessary to improve seed vigor tests efficiency in order to shorten test time. This research purpose were to determine exact radicle observation time in RE test and determine correlation between RE test results and the vigor change and seed viability. The results showed that radicula observations using RE method can be carried out after the seeds are germinated for 96 hours at a 25+20C temperature. Variety Suri 4 has the highest RE yield of 95.25% but has the lowest average germination time of 28.87. The second result show there is positive correlation between RE value to the change IV,Kct, DB, PTM. It means the higher value of IV,Kct, DB and PTM, the higher RE value. The correlation between RE and MGT and LPK changes shows a negative correlation. The higher MGT and LPK values, the lower RE value.
