Abstract

Robusta coffee (Coffea canephora) germination takes a long time because robusta coffee beans have a hard seed coat that makes it difficult for water and oxygen to penetrate, causing the germination process to be hampered. The purpose of this study is to determine the gibberellin concentration, and the proper soaking time in the germination of robusta coffee seeds and to obtain the best interaction between gibberellin concentration and soaking time on the viability of coffee seeds that have been peeled. The research was conducted at the Dharmasraya Campus III Seed Technology Laboratory from July to September 2022. This study was a two-factorial experiment in a completely randomized design (CRD). The first factor was the concentration of gibberellins which had four levels: 0, 100, 200, and 300 ppm, the second factor was soaking time which had 3 levels: 8, 16, and 24 hours. The results showed that the treatment with gibberellin of 300 ppm significantly increased seed germination, plumule, radicle elongation, and vigor index on robusta coffee seeds. And, the best soaking time of 24 hours, the long soaking treatment had a significant effect on the germination power of robusta coffee seeds. With the best treatment, a gibberellin concentration of 300 ppm and 24 hours, the interaction between gibberellins concentration and soaking time can increase the germination power of robusta coffee seeds.

Abstract

Coffee is one of the plantation commodities that has significant economic value. A factor that needs to be considered in coffee plant cultivation is good planting media composition. This study aims to determine the effect of planting media composition on the growth of robusta coffee seedlings. This study used a Completely Randomized Design with treatments M0= Soil: 100%, M1= Soil: 50% + Coffee Husk Compost: 25% + Rice Husk: 25%, M2= Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25%, M3= Soil: 25% + Coffee Husk Compost: 25% + Rice Husk: 50%. The analyses conducted were compost analysis and initial and post-incubation soil analysis. Observation data were analyzed using the F test followed by DNMRT at the 5% level. The research results show that the provision of coffee husk compost and rice husks affects the chemical properties of the soil and the growth of coffee seedlings. The planting media composition of Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25% proved to increase the pH of the planting media from 5.5 to 6.6, increase in total N-value from 0.2% to 0.5%, available P from 18.6 ppm to 38.5 ppm and the soil CEC from 7.6 me/100g to 36.6 me/100g. This planting media composition also makes it possible to enhance the growth of robusta coffee seedlings in plant height, stem diameter, number of leaves, leaf width, and root volume. Thus, this planting media composition is a suitable medium for the growth of robusta coffee seedlings.
