Abstract

Cocoa seeds (Theobroma cacao L.) are recalcitrant seeds with high water content and rapidly decreasing viability during storage. Therefore, appropriate storage media are required to maintain seed quality. This study aimed to determine the interaction effect of storage media type and storage duration, and to determine the best storage media and storage duration on the viability and early growth of MCC 02 cocoa seedlings. The study was conducted from January to April 2026 in Glindah Village, Kedamean District, Gresik Regency, using a factorial Completely Randomized Design (CRD) with two factors: storage media type (cocopeat, rice husk charcoal, and sawdust) and storage duration (7, 14, 21, and 28 days). Analysis of Variance (ANOVA) was used for data analysis, followed by an Honestly Significant Difference (HSD) test at the 5% level. The results showed a significant interaction between the combination of storage media types and storage duration on the observed parameters of cocoa seedling height at 21 days after planting (HST), 28 days after planting (HST), and 35 days after planting (HST), as well as the fresh weight of cocoa seedlings. The single treatment of cocopeat storage media type provided the best value for germination capacity of 67%, maximum growth potential of 86%, fresh weight of seedlings of 5.29%, length of seedlings of 25.82 cm, height of seedlings of 19.96 cm, and fresh weight of seedlings of 7.21 grams. The single treatment of 7 days storage duration provided the best results in the parameters of germination capacity, maximum growth potential, fresh weight of seedlings, fresh weight of seedlings, root length of seedlings, and fresh weight of roots compared to other storage durations. Keywords: Rice husk charcoal, Recalcitrant seeds, Cocopeat, Cocoa (Theobroma cacao L.), Sawdust
