Abstract

This study aims to determine the growth rate of Arabica coffee (Coffea arabica L) in the pre-nursery stage with the addition of chicken feather keratin fertilizer and blood serum. This study used a factorial randomized block design (RAK) with two factors, namely. The first factor is chicken feather keratin fertilizer with 4 treatment levels (0.5, 10, 15 gr.), while the second factor is the addition of blood serum with 4 treatment levels (0.15, 30, 45 ml / L). This study is expected to provide information about the effect of chicken feather keratin and blood serum on the growth of Arabica coffee seedlings, and can be a reference.

Abstract

highlights the need for innovation in nursery media based on locally available organic materials. This study aimed to analyze the effects of guano fertilizer and stalagmite sediment originating from Lawar Cave, Tangkahan, Langkat Regency, on the early growth of Arabica coffee seedlings (Coffea arabica L.). The research was conducted in Kutalimbaru District, Deli Serdang Regency, from May to July 2025 using a factorial Randomized Block Design (RBD) with two factors: guano fertilizer (0, 50, 100, and 150 g/polybag) and stalagmite sediment (0, 20, 30, and 40 g/polybag), with three replications. The observed parameters included plant height, number of leaves, leaf area, and root length. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test at the 5% significance level. The results showed that the interaction between guano fertilizer and stalagmite sediment had significant to highly significant effects on plant height and number of leaves. Application of guano at 50 g/polybag increased plant height by 1.38%, while stalagmite sediment at 30 g/polybag increased plant height by up to 2.97%. The highest number of leaves was obtained with guano at 150 g/polybag, showing an increase of 5.15%. Root length was significantly affected by stalagmite sediment, with an increase of up to 6.03%, whereas leaf area showed no significant differences among treatments. It can be concluded that the combination of guano fertilizer and stalagmite sediment effectively enhances the early growth of Arabica coffee seedlings and has strong potential to support sustainable coffee nursery systems.Research purposes.

Abstract

This study aims to determine the effect of auxin concentration (Rootone-F) and liquid organic fertilizer (POC) from lamtoro leaves (Leucaena leucocephala) on the growth of robusta coffee seedlings (Coffea canephora). The study was conducted in March–May 2025 in Sampe Cita Village, Kutalimbaru District, Deli Serdang Regency, North Sumatra. The research method used a factorial Randomized Block Design (RAK) with two factors, namely the concentration of lamtoro leaf POC (M0=0 ml, M1=200 ml, M2=250 ml, M3=300 ml) and the concentration of Rootone-F (A0=0 ml, A1=200 ml, A2=250 ml, A3=300 ml), with three replications. The parameters observed included plant height, leaf area, number of leaves, and root length. The results showed that the administration of lamtoro leaf POC and Rootone-F significantly affected plant height, leaf area, and number of leaves of robusta coffee seedlings. The best treatment was obtained with a combination of 300 ml of lamtoro leaf POC and 250 ml of Rootone-F which resulted in optimal vegetative growth. Increasing the concentration of Rootone-F tended to decrease root length due to the biphasic effect of auxin on root growth. It can be concluded that the use of lamtoro leaf POC and Rootone-F at the right dosage can significantly increase the growth of robusta coffee seedlings.

Abstract

Seedling quality is a determining factor in the success of arabica coffee cultivation. This study aimed to examine the effect of organic planting media and amino acid fertilizer on the growth of arabica coffee seedlings (Coffea arabica) Sigarar Utang variety. The research was conducted at the experimental field of the Agrotechnology Study Program, Pancabudi Development University, Glugur Rimbun Village using a factorial Randomized Block Design (RBD) with two factors. The first factor was organic planting media composition (chicken manure and topsoil) with four levels: M0 (control), M1 (150 grams), M2 (300 grams), and M3 (450 grams). The second factor was amino acid fertilizer dosage with four levels: A0 (control), A1 (2 grams/liter), A2 (4 grams/liter), and A3 (6 grams/liter), resulting in 16 treatment combinations with 3 replications. Parameters observed included plant height, stem diameter, leaf number, root length, and root volume at 4, 8, and 12 weeks after planting. Results showed that the M3A3 combination treatment (450 grams organic media + 6 grams/liter amino acid fertilizer) provided the best results for all observation parameters at 12 weeks with plant height of 18.083 cm, stem diameter of 2.742 mm, and leaf number of 13.417 leaves. This research contributes to developing quality and sustainable arabica coffee seedling techniques to support national coffee productivity.
