Abstract

The Robusta coffee plant (Coffea canephora) is included in the Rubiaceae family and the Coffea genus. The problem in breeding Robusta coffee plants is that Robusta coffee seeds cannot be developed generatively because of the type of cross-pollination, so they must be propagated vegetatively by cuttings, namely slow root growth and rooting. weak so shoot formation is slow. To overcome this problem, liquid NPK fertilizer (24:20:05) was used with the aim of producing optimal cutting growth. The aim of this research was to determine the effect of the dose and frequency of application of liquid NPK fertilizer (24:20:05) on the growth of Robusta coffee cuttings. The method used was a factorial Randomized Block Design (RAK) consisting of 2 factors and 3 replications. Factor 1 consists of F0: 0 ml/polybag, F1 (25 ml/polybag), F2 (50 ml/polybag), F3 (75 ml/polybag), F4 (100 ml/polybag). The second factor is the frequency of fertilization (M) which consists of M1: Application once a week M2: Application once every 2 weeks M3: Application once every 3 weeks. The research results showed that there was an interaction between the dose of liquid NPK fertilizer and the frequency of fertilization on Robusta coffee cuttings (1) which had a very significant influence on the observed variables of stem diameter, number of branches and leaf area. (2) Giving a dose of liquid NPK fertilizer to Robusta coffee plant cuttings has a very real influence on all variables. (3) The effect of fertilization frequency on Robusta coffee plant cuttings has a very real influence on the variables of stem diameter and number of branches.

Abstract

Low coffee production and quality are two major problems of the Indonesian economy that must be addressed, especially in smallholder plantations. The use of Growth Regulators (ZPT) and Planting Media in coffee with the grafting method is expected to help in the growth of coffee plants. This study was designed using a Factorial Completely Randomized Design (CRD) consisting of 2 factors, namely ZPT Growtone Concentration (G0: Control, G1: 20/250 ml, G2: 25g/250 ml, G3: 30g/250 ml) and Composition of Planting Media Soil, Manure, and Sand (M0: Control, M1: 1:1:1, M2: 1:2:1, M3: 1:3:1). Each treatment was repeated three times. The parameters analyzed included plant height, number of roots, root length, root weight, stem diameter, and number of leaves. All data obtained in the study are presented in the form of tables and diagrams. The data obtained will be analyzed using analysis of variance (ANOVA). To test the effect of treatment on the observed variables, if there is a significant difference, the DMRT (Duncan Multiple Range Test) further test will be conducted at the 95% confidence level. The results showed that the combination of ZPT Growtone and Planting Media types of soil, manure, and sand had a significant effect on the number of branches parameter, and each factor also had a significant effect on the root length parameter. The best treatment is the combination of  ZPT Growtone 20g/250 ml and Planting Media Composition 1:1:1. The treatment has the highest number of branches with an average of 2.67. The effect of the two factors on the grafting cuttings seedlings on the root length parameter was 16.83 and 16.96, respectively.
