PENENTUAN RASIO DAN DURASI MATRICONDITIONING DENGAN VERMICOMPOST UNTUK MENINGKATKAN MUTU BENIH KEDELAI (Glycine max L. Merr.)

Abstract

The rapid deterioration of soybean seeds during storage severely limits the availability of high-quality planting stock. Seed invigoration, specifically through matriconditioning, a technique involving controlled hydration using a moist solid medium, offers a method to improve the germination capacity of aged seeds. This study was thus designed to ascertain the optimal dosage of vermicompost utilization as a matriconditioning agent for improving the physiological quality of soybean seeds. Vermicompost, the product of organic matter decomposition, provides a comprehensive nutrient profile that may enhance seed physiological quality. The research aimed to determine the optimal vermicompost dosage for improving soybean seed physiological quality. A two-factor Factorial Completely Randomized Design (CRD) with four replications was employed. The factors were the priming ratio seed (g): vermicompost (g): water (ml) at four levels R0​ (control), R1​ (12:14:12), R2​ (12:14:13), R3​ (12:14:14) and priming duration four levels: D0​ (control), D1​ (6 hours), D2​ (12 hours), D3​ (18 hours). The experiment used Argomulyo cultivar seeds (initial germination 70-79%). Results indicated that the most effective invigoration treatment utilized the vermicompost priming ratio of 12:14:12 and an incubation period of 18 hours at ambient conditions (25±2 ºC).
