Comparison of Planting Media Types on Vegetative Growth of Mini Potato Cuttings (Solanum Tuberosum L.) Granola L Variety

Abstrak

Potato (Solanum tuberosum L.) is a horticultural plant that is one of the commodities that plays an important role and priority to be developed and has the ability in food diversification. This study aims to determine the effect of planting media on the vegetative growth of potato mini cuttings and to determine what media composition provides the best results for the vegetative growth of potato mini cuttings. The study was conducted in Kebayaken Village, Naman District, Teran, Karo Regency at an altitude of ± 1,200 meters above sea level. The study was conducted for 3 months, starting from November to January. The study was designed with a Completely Randomized Design (CRD) Non-Factorial with 8 factors with 2 replications. The factors studied were (A0) Soil, (A1) Compost, (A2) Rice Husk Charcoal, (A3) Cocopeat, (A4) Chicken Manure, (A5) Compost + Chicken Manure (1:1), (A6) Rice Husk Charcoal + Chicken Manure (1:1), (A7) Cocopeat + Chicken Manure (1:1). The results of the study showed the effect on the vegetative growth of mini potato cuttings, namely the percentage of death, crown diameter, stem diameter, plant height, number of leaves, and shoot length. The planting medium that gave the best results was found in A7 (Cocopeat + Chicken Manure (1:1).
