Abstract

Kale is one of the family plants with collard, cabbage, and broccoli, but not well known by the people because not many farmers have cultivated this plant, but the demand for kale plants continues to increase. This study aims to determine the composition of planting media and the dose of gold snail liquid organic fertilizer for the growth and yield of kale plants, held from April to June 2022 in Sumberkembar Village, Probolinggo Regency. The research design used is the Group Randomized Design (RAK) method which consists of 2 factors, namely the composition of the planting media with 3 levels of treatment, namely: M1 (Soil: Husk Charcoal: Manure 3: 1: 1), M2 (Soil: Husk Charcoal: Manure 2: 2: 1), M3 (Soil: Husk Charcoal: Manure 1: 3: 1) and the provision of POC gold snails as many as 4 levels, namely: P0: Control, P1: 10 ml/Plant, P2: 20 ml/Plant, P3: 30 ml/Plant. Based on the results of the study, it can be concluded that: 1) The treatment of the composition of the planting media M2 (Soil: Husk Charcoal: Manure 2: 2: 1) provides optimal results on the parameters of root length, 2) The POC dose treatment of gold snails P2 (20 ml/plant) provides optimal results on plant height parameters and the number of leaves and 3) there is no interaction between the treatment of the composition of the planting media (M) and the POC dose of gold snails (P) on all parameters. Keywords: Kale Nero Lacinato, Planting Media, Liquid Organic Fertilizer of Golden Snail
