Abstract

Dragon fruit plants originating from Central and South America have not been widely cultivated. This plant has only been cultivated intensively in several countries such as: Israel, Colombia, Nicaragua, Vietnam, Thailand, China and Australia. Macroscopic identification showed that the fungi associated with dragon fruit stems had similarities to the colony form of Colletotrichum gloeosporioides sp. Trichoderma is known to have antagonistic abilities against pathogenic fungi. Trichoderma is easily found in soil ecosystems and plant roots. The method in this study is a survey method. Determination of the sample using purposive sampling or Judgmental sampling method, namely purposive sampling is a sampling method that selects objects (vines) that are considered attacked or have symptoms of pathogen attack. Trichoderma sp is also tolerant to stress and able to inactivate pathogenic microbial enzymes. In addition, Trichoderma sp. Able to produce enzymes that hydrolyze pathogenic cell walls which will inhibit the synthesis of pathogenic cell walls and increase their fungicidal activity, as a result of which pathogenic fungi experience a decrease in growth rate.

Abstract

This research aims to evaluate how effective the use of organic amendments and Trichoderma mushrooms is in increasing the quality of Arabica coffee seeds planted on Andisol type land in the Namanteran District, Karo Regency. The method used is a random igroup design (RAK) with a single treatment design (non-factorial), which consists of eight different treatments and each of them is repeated four times. The treatments include: A0 (no treatment/control), A1 (compost 20 g + Trichoderma 10 g per plant), A2 (biochar 20 g + Trichoderma 10 g per plant), A3 (manure 20 g + Trichoderma 10 g per plant), A4 (manure 20 g + biochar 20 g + Trichoderma 10 g per plant), A5 (compost 20 g + biochar 20 g + Trichoderma 10 g per plant), A6 (compost 20 g + 20 g + Trichoderma 10 g per plant), and A7 (biochar 20 g + manure 20 g + Trichoderma 10 g per plant). The parameters observed in this research include plant height, stem diameter, leaf number, leaf surface area, and root system length. This treatment showed a real influence on all plant growth parameters, including height, stem diameter, number of leaves, leaf area, and root length at ages 2 and 3 BST.Keywords: Coffee, Seedling Cultivation, Organic Amendment, Trichoderma
