Abstract

Cocoa is a plantation crop that has the potential to increase state income. In Bali, the highest cocoa production is in Jembrana Regency. Increasing the productivity of the cocoa plant can be achieve by using environmentally friendly fertilizer such as Arbuscular Mycorrhizal Fungi (AMF). The aim of this research is to obtain indigenous AMF isolates and their propagation with different planting media and water stress. The research was conducted from July to January 2021. Sampel AMF for islolation and identification was taken from Banjar Pangkung Medahan, Pulukan Village, Pekutatan District, Jembrana Regency, while isolation and identification of AMF was conducted at Agronomy and Horticulture Laboratory, Faculty of Agriculture, Udayana University, Laboratory of Plant Diseases, Laboratory of Genetic Resources and Molecular Biology of Udayana University and Greenhouse of Experimental Garden Faculty of Agriculture, Denpasar. This research used in propagating of spores of AMF was a Completely Randomized Design (CRD) with 2 factors and 4 replications. The first factor was planting medium which consisted of four treatment levels (soil planting medium, soil with sand growing media, soil with compost growing media, and sand with compost soil growing media) and the second factor was water stress which consisted of three treatment levels (ground water content of 100%, 70%, and 40% of field capacity). The results of isolation and identification showed that there were three genera of AMF spores found, i.e. Glomus, Gigaspora, Acaulospora. The results of spore propagation showed that soil and sand growing media with a combination of soil moisture content of 40% water field capacity produced the highest spores, which was 62 spores on average.

Abstract

Coffee is very important agro industry in Bali Province. The coffee center in Bali which is already famous for its geographic indication protection status is Kintamani District, which is the largest producer of Arabica coffee and an icon of Arabica coffee in Bali. Therefore, efforts are needed to maintain coffee production through the selection of fertilizers that do not harm the environment, for example biological fertilizers derived from arbuscular mycorrhizal fungi (AMF). This study aimed to find the best growing media composition and optimal soil water content and the interaction between the two treatments for endomycorrhizal spore propagation. This research was arranged in a completely randomized design (CRD) with 2 factors and 4 replications. The first factor was composition of growing media which consisted of four levels, i.e. Mt (soil only), Mp (soil and volcanic sand with ratio of 1:1/v:v), Mk (soil and compost with ratio of 1:1/v:v), and Mc (soil, volcanic sand, and compost with ratio of 1:1:1/v:v:v). The second factor was water stress which consisted of three levels, i.e. A0 (100% field capacity), A1 (70% field capacity), and A2 (40% field capacity). The highest spore multiplication results were obtained in the combination treatment of MpA0 as much as 55,00 spores with an increase of 120%. Meanwhile the combination treatment of MkA2 produced the lowest spores as much as 34.25 spores with an increase of 37%.

Abstract

Pulukan Village, located in the Jembrana Regency of Bali, is one of the primary communities that produce organic cocoa. The huge demand for organic cocoa beans has not been satisfied due to the poor production per hectare. One of the causes is that cocoa farmers in the village have trouble obtaining the recommended volumes of organic fertilizers and biopesticides. To raise the yield of organic cocoa, this service is provided to farmers to enhance their knowledge and ability to create organic fertilizers and biopesticides from local components. The activities are implemented through counselling and training on producing organic fertilizers and biopesticides, followed by support in applying organic fertilizers and biopesticides. Participants in training and mentoring are encouraged to work together and learn concurrently. The implementation of the counselling on the production of organic fertilizers and biopesticides was excellent, as indicated by the fact that 93.33 per cent of participants said they comprehended the material presented very well, and 100 percent said it was fascinating and very beneficial. Participants could produce excellent organic fertilizers and biopesticides due to training activities involving direct practice. As a result of training in plots, organic fertilizers, and biopesticides can improve farmers' ability to directly implement fertilizing methods and disease pest management in organic cocoa farming. Applying organic fertilizers and biopesticides in the plot revealed that cocoa trees treated with organic fertilizers and biopesticides had greater growth and fewer disease-causing insect infestations than control trees.This motivated the service volunteers to implement the plot's best practices on their organic cocoa crops.
