Invigoration of expired purple eggplant (Solanum melongena L.) variety Reza seeds by soaking them using potassium nitrate (KNO3). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-13 Tahun 2025, Palembang 20 Oktober 2025. (pp. x–y). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Purple eggplant seeds that have passed their storage period often experience decrease in germination capacity, resulting in low germination rates and reduced seed germination ability. This situation has the potential to hinder the cultivation of purple eggplant (Solanum melongena L.) variety Reza, considering that this plant requires high-quality seeds. This study aimed to determine the best invigoration treatment with KNO3 to increase the germination of expired purple eggplant seeds. This study was conducted at the Seed Technology Laboratory, Faculty of Agriculture, Sriwijaya University, Indralaya, Ogan Ilir Regency in October 2024. The method used during the study was a Completely Randomized Design (CRD) with six KNO3 concentration treatments, namely P0 (0%), P1 (0,1%), P2(0,2%), P3 (0,3%), P4 (0,4%), and P5 (0,5%) which were soaked for 24 hours, repeated three times, and each replication consisted of 24 petri dishes, each petri dish containing 100 seeds. Based on the results of the analysis of variance (ANOVA) and 5% BNT test, it shows that invigoration of expired purple eggplant (S. melongena L.) Reza variety seeds using KNO3 with a concentration of 0,5% has a very significant effect on germination speed, germination power, growth potential, growth uniformity, fresh weight of sprouts, dry weight of sprouts, plumule length, radicle length. However, it only has a significant effect on the vigor Index.]]>
