The purpose of this study was to determine the potential of agro-climate, technology of cultivation, harvest and postharvest chrysanthemums. This study uses survey method, through the collection of primary data and secondary data. This research is located in the village of Pancasari, District Sukasada, Buleleng Bali Province. Descriptive survey conducted on 40 respondents chrysanthemum growers using the component identification of determinants of commodity production chrysanthemum include: site selection, infrastructure, crop production processes and post-harvest handling. The survey results showed that 100% of the farmers have chosen a suitable location with agro-climatic conditions required by the chrysanthemum plant, and 86.09% of the farmers have been using the means needed to support the process of crop production. In the process of production of 78% in accordance with the operational procedures. At the stage of harvest and post-harvest handling 80% have been implemented by farmers and some still use conventional methods of handling. Thus Pancasari village has a potential location for the cultivation of chrysanthemum as a mainstay commodity.

The purpose of this study was to determine the effect between types of cuttings and between varieties of plant material on any type of plant material chrysanthemum cuttings. Methods trial with a randomized block design factorial nested pattern. The results showed that the treatment effect of plant cuttings type of material does not give a significant effect on all parameters observed. Influence of cuttings between varieties at any plant material gives a significant influence on the parameters, the maximum number of leaves, flower stalks weight and economical weight of fresh flowers. The average weight of the highest economical due to the influence between the varieties in each type of plant material cuttings from mother plants found in fiji white varieties 93.83 g and not significant with 93.46 g fiji yellow varieties. So also in effect between varieties on any type of cuttings from the plant material production plant gives the same result.

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 factorial randomized block design in the field in a green house. This study uses two factors, namely: the first factor, the dose of Trichoderma sp consists of 3 levels each: 0.25 tonnes ha.-1 , 0.50 ton ha-1, and 0.75 ton 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 treatment dose of Trichoderma sp 1.0 ton ha-1that isamounting to 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 concentration of Beauveria bassiana 45 g / l produce the highest economic weight of fresh flowers and the lowest intensity of disease attack of 79.55 g and 42.08% when compared to the lowest treatment.

This study aims to determine the growth response and yield of chrysanthemum plants in the application of several types of mulch and organic fertilizer. This research uses the basic design of Randomized Block Design with the factorial pattern with 2 factors and 3 replications. The first factor is mulch treatment consisting of 3 levels ie without mulch, rice husk mulch, and black silver plastic mulch. The second factor is organic fertilizer consists of 3 levels namely petrogenic, cow manure and chicken manure. The research results showed that the highest weight of flower stalk was obtained in silver black mulch treatment, increase of 9.63% when compared with the weight of the lowest flower stalk. The highest economic fresh weight was obtained in mulch treatment, increase of 17.53% when compared with the lowest fresh economic weight on mulch rice husk mulch treatment weighing. The highest weight of the flower stalk was obtained in the treatment of cow manure, increased of 10.14% when compared with the lowest weight of the flower stalk obtained in the treatment of cow manure weighing. The highest economic fresh weight was obtained in the cow manure treatment, which increased by 9.91% when compared with the lowest fresh economic interest weight obtained in the treatment of petrogenic fertilizer weighing. Keywords: type mulch, petrogenic, manure; flower

The study, entitled utilization of water hyacinth and dolomite fertilizer in chrysanthemum cultivation, aims to determine the dosage of water hyacinth and dolomite fertilizer and their interactions with chrysanthemum cultivation. The research method used a randomized block design with a two-factor factorial pattern, namely: three levels of water hyacinth: 1.5 tonnes ha-1, 3.0 tonnes ha-1, and 3.5 tonnes ha-1, and three levels of dolomite fertilizer: 150 kg ha-1, 300 kg ha-1, and 450 kg ha-1. The interaction between water hyacinth dose and dolomite fertilizer had no significant effect on all variables. Treatment of water hyacinth dosage 3.5 ton ha-1 resulted in the highest flower stalk length and fresh weight of 155.30 cm and 74.52 g, the results increased 9.88% and 25.93% when compared to the lowest treatment. Dolomit fertilizer dose of 450 kg ha-1 yielded the highest flower stalk length and fresh weight of 150.03 cm and 67.23 g, the yield increased by 4.21% and 7.47% when compared to the lowest treatment.
