Abstract
This research is entitled to increase the production and quality of chrysanthemum cut flowers through the application of biological agents, with the aim of knowing the dosage of Trichoderma sp. and the concentration of Beauveria bassiana and its interaction on chrysanthemum cut flowers. The research method used a factorial randomized block design in the field in a green house. In this study, two factors were used, namely: the first factor, the dose of Trichoderma sp consisted of 3 levels, respectively: 0.25 tonnes ha-1, 0.50 tonnes ha-1, and 0.75 tonnes ha-1. The second factor of Beauveria bassiana consists of 3 levels, namely: 15 g / l, 30 g / l, and 45 g / l. The results showed the interaction between the doses of Trichoderma sp. and the concentration of Beauveria bassiana had no significant effect on all observed variables. Treatment of Trichoderma sp. very significant effect (P <0.01) on all observed variables. The highest economic weight of fresh flowers and the lowest intensity of pest attack occurred in the Trichoderma sp. 0.75 ton ha-1 dose treatment, namely 85.97 g and 25.19% when compared to the lowest treatment. The treatment of Beauveria bassiana concentration had a significant effect (P <0.05) on all observed variables, had a very significant effect (P <0.01) on the maximum plant height and flower stalk height. Treatment with the concentration of Beauveria bassiana 45 g / l produced the highest economic weight of fresh flowers and the lowest disease intensity of 79.55 g and 42.08% when compared to the lowest treatment
