Abstract

This study evaluated the effect of rhizosphere bacteria microcapsule fertilizer and chicken manure fertilizer on the growth of robusta coffee seedlings (Coffea canephora L.) in an effort to develop environmentally friendly superior seedlings. Using a two-factorial Completely Randomized Design with 16 treatments and 5 replications, variations in doses of chicken manure fertilizer (0, 100, 200, 300 grs) and rhizosphere bacteria microcapsules (0, 5, 7.5, 10 grs) were tested. The results showed that a dose of 100 grs of chicken manure fertilizer (K1) gave the best growth response in all parameters, with plant height reaching 51.40 cm at 4 BSPT, an increase of 44.8% compared to the control. Root length showed a non-linear response pattern, where K1 produced the highest root length (30.68 cm²) and the highest dose (K3) produced the lowest root length (24.36 cm²). The number of leaves and leaf area also increased significantly in the K1 treatment compared to the control. Rhizosphere bacteria microcapsules provide positive effects through root growth stimulation and phytohormone production that increases nutrient absorption efficiency. These findings emphasize the importance of optimizing the dosage of chicken manure fertilizer and rhizosphere bacteria microcapsules for sustainable robusta coffee seedling growth.

Abstract

The high incidence of pest attacks in coffee plantations has led to a decline in both the productivity and quality of coffee. As an initial step in addressing this issue, it is essential to collect data on the types of pests that attack coffee plantations in a particular area. This study aimed to identify pest species and determine appropriate control strategies in Arabica coffee (Coffea arabica L.) plantations in Sigarang-garang Village, Naman Teran Subdistrict. Pest observation was conducted using the random sampling method, and the data were analyzed descriptively. The results showed that the main pests found in the coffee plantations of Sigarang-garang Village included the coffee berry borer (Hypothenemus hampei), coffee branch borer (Xylosandrus spp.), and green scale insect (Coccus viridis). Effective pest control requires several specific measures, including the application of pesticides, regular pruning, and crop rotation.

Abstract

Coffee (Coffea sp) is one of the most important plantation commodities in Indonesia, largely due to its considerable economic value. However, coffee production faces significant challenges from pests such as the coffee berry borer (PBKo) (Hypothenemus hampei F), which can cause severe damage to crops, with losses reaching up to 100%. Biological control agents, particularly the entomopathogenic fungus Beauveria bassiana, have gained increasing attention as environmentally friendly alternatives to chemical pesticides. While the efficacy of B. bassiana against H. hampei has been widely documented, most previous studies have primarily targeted the adult or larval stages, often overlooking the differences in susceptibility among the various metamorphosis phases. This study addresses this research gap by systematically evaluating the effectiveness of B. bassiana as a biological control agent against PBKo across each stage of the pest’s metamorphosis-egg, larva, pupa, and imago-under in vitro conditions. Using a controlled experimental design, we assessed mortality rates in each developmental phase after exposure to B. bassiana treatment. The findings of this study are expected to provide comprehensive insights into the phase-specific efficacy of B. bassiana, identifying which metamorphic stage is most vulnerable to fungal infection. This knowledge is anticipated to improve biological control strategies, ultimately supporting more targeted and sustainable integrated pest management practices for coffee plantations. These advancements can enhance coffee yields and quality while reducing reliance on synthetic chemical pesticides.

Abstract

Indonesia is the fourth largest coffee producing country in the world. However, Indonesian coffee production has decreased due to disease caused by Colletotrichum coffeanum F.Noack. This research aimed to utilize endophytic bacteria as biocontrol to inhibit growth and development of Colletotrichum coffeanum F.Noack.. The endophytic bacteria used came from the isolation of Arabica coffee plant stems. The isolation results obtained were 5 isolates with different characteristics. Based on the results of the antagonist test, there are 2 out of 5 endophytic isolates that have the potential to inhibit pathogen growth. The results of the largest inhibition zone were 17,18mm in Sp.BS2 and the results of the smallest inhibition zone were 14,98 mm in Sp.BS5. In the growth rate of endophytic bacteria, the largest value is 351 x 1015 in isolate Sp.BS5 in 48 hours and the smallest value is 8 x 105 in isolate Sp.BS5 in 6 hours. In the IAA (Indole Acetic Acid) test results, the largest value is 66.36 ppm in treatment P1J3 (pH 6.5; 72 hours) and the smallest value is 26.89 ppm in treatment P3J3 (pH 7.5; 72 hours). The results of these values indicate that endophytic bacterial isolates from Arabica coffee plant stems have the potential to inhibit the growth of Colletotrichum coffeanum F.Noack.

Abstract

This study aims to evaluate the effect of rhizosphere bacteria microcapsule fertilizer application and chicken manure fertilizer on the growth of robusta coffee seedlings (Coffea canephora L.). The background of the study is based on the need for environmentally friendly superior coffee seedlings, considering that the continuous use of inorganic fertilizers has the potential to reduce soil fertility. Rhizosphere bacteria-based biofertilizers are expected to be able to increase plant growth organically, while microencapsulation technology is used to increase the effectiveness and resistance of bacteria in the environment. This study used a two-factorial Completely Randomized Design with 16 treatments and 5 replications, involving variations in the dose of chicken manure fertilizer (0, 100, 200, 300 grams) and rhizosphere bacteria microcapsules (0, 5, 7.5, 10 grams). The parameters observed included plant height, number of leaves, leaf area, stem diameter, and root length. The results showed that the application of rhizosphere bacteria microcapsules at a dose of 7.5 grams (M2) significantly increased the height of robusta coffee seedlings, while the dose of 300 grams of chicken manure fertilizer (K3) also had a significant effect on plant height growth. However, the treatment did not provide a significant difference in the number and area of leaves. This study concluded that the combination of rhizosphere bacteria microcapsules and chicken manure fertilizer can be an environmentally friendly solution to optimally increase the growth of robusta coffee seedlings

Abstract

This research focused on assessing how the interaction between planting media composition and vesicular arbuscular mycorrhizal (VAM) biofertilizer influences the growth of Arabica coffee seedlings. The formulated hypothesis helped direct the study toward identifying the most favorable conditions for seedling development. The experimental design employed was a factorial randomized block design (RBD), comprising 16 different treatment combinations, each repeated twice. The first treatment variable (Factor P) involved different mixtures of topsoil, rice husk, and compost: P0 = 100% topsoil, P1 = 60% topsoil + 20% rice husk + 20% compost, P2 = 60% topsoil + 40% rice husk, and P3 = 60% topsoil + 40% compost. The second variable (Factor M) concerned the application of VAM biofertilizer in doses of 0 g (M0), 0.5 g (M1), 1 g (M2), and 1.5 g (M3). Statistical analysis showed that the interaction between media composition and VAM biofertilizer significantly influenced all growth indicators measured in the Arabica coffee seedlings.
