Efek Berbagai Media Tanam Dan Pupuk Organik Cair (Poc) Terhadap Pertumbuhan Bibit Kopi Robusta (Coffea Robusta L.)

Abstract

The effects of various growing media and liquid organic fertilizers on the growth of robusta coffee (Coffea robusta L.) seedlings. The research was conducted for 12 weeks (3 months) from March to June 2020. The research was conducted at the Agrotechnology Experimental Garden, Widya Gama Mahakam University, Samarinda. This study aims to determine: 1. The right planting media for the growth of robusta coffee (Coffea robusta L.) seedlings 2. Liquid organic fertilizer (POC) is appropriate for the growth of robusta coffee plant seedlings (Coffea robusta L.). 3. The interaction between planting media and liquid organic fertilizer (POC) on the growth of robusta coffee (Coffea robusta L.) seedlings. This study used a factorial randomized block design (RBD) with 2 factors and repeated 3 times. The first factor is the Planting Media (M) which consists of 4 levels, namely, M1 = Soil, M2 = Soil + Rice Husk (2: 1), M3 = Soil + Sawdust (2: 1), M4 = Soil + Coconut Coir ( 2: 1). The second factor is Liquid Organic Fertilizer (P) consisting of 3 levels, namely: P0 = Topsoil (control), P1 = POC 50% Fragrant Lemongrass Tofu Wastewater (ALTSW) (500 ml ALTSW + 500 ml water), P2 = POC Extract Gamal leaf (EDG) (500 ml EDG + 500 ml water). Based on the research results, the following conclusions can be drawn: 1. There is a significant effect of the application of growing media on the increase in height, stem diameter, and the number of leaves. Soil media with rice husks gave the best response to the growth of robusta coffee (Coffea robusta L.) seedlings. 2. There was a significant effect of POC application on height increase, stem diameter, and the number of leaves. The liquid organic fertilizer of Gamal leaves gave the best response to the growth of robusta coffee (Coffea robusta L.) seedlings. 3. There is a media interaction with liquid organic fertilizer (POC) which has a significant effect on the increase in height, stem diameter, and number. The combination of soil growing media treatment with rice husks and Gamal leaf POC gave the best response to the growth of robusta coffee (Coffea robusta L.) seedlings. The expected output is to provide information about the best planting media for the growth of Robusta coffee seeds for the community. Providing information about the best liquid organic fertilizers for the growth of Robusta coffee seeds for the community.
