<![CDATA[[ORGANIC PRIMING FOR THE INVIGORATION OF DETERIORATED SORGHUM SEEDS (Sorghum bicolor (L.) Moench)]. Seed deterioration in new superior varieties (VUB) is one of the constraints in crop development, including sorghum Bioguma 3 Agritan. This study aimed to evaluate the effects of organic priming and soaking duration on the viability of deteriorated sorghum seeds. The experiment was conducted at the Seed Technology Laboratory of UPN “Veteran” Jawa Timur using a factorial completely randomized design with two factors, namely type of organic priming (sprout extract, spirulina extract, and combined extract) and soaking duration (6, 12, 18, and 24 h). The observed variables included germination percentage, maximum growth potential, fresh weight of normal seedlings, and dry weight of normal seedlings. The results showed that, in severely deteriorated sorghum seeds, priming with 10% mung bean sprout extract for 6 h produced the highest germination percentage, increasing germination by 97.17% compared with the untreated control, and gave the best result for maximum growth potential. This treatment was comparable to 10% spirulina extract for 12 h and combined extract (sprout extract +spirulina) for 12 h. The highest fresh weight of normal seedlings was obtained from 10% spirulina extract for 12 h, whereas dry weight of normal seedlings was relatively similar among treatments. Soaking for 24 h in all types of organic priming was not recommended because it tended to reduce the viability of deteriorated sorghum seeds.]]>
