Abstract

The market outlook for chrysanthemum flowers is extremely optimistic, as domestic and international consumer demand has increased over the past five years. The development of chrysanthemum plants is anticipated to positively affect the region's employment opportunities, economic growth, and service sector growth. Along with the increasing intensity of chrysanthemum cultivation in various regions, more in-depth research on chrysanthemum flowers is required to improve quality and added value and utilize the potential of locally available resources that are simple for farmers to apply and have a significant impact on improvement. The majority of chrysanthemum cultivation business actors are small farmers. Chrysanthemum plant technology is distinct from other horticultural crops, requiring special maintenance such as Disbudding, adding artificial light, artificial Defoliation, and the erection of plant enforcement nets. The research method employs the Factorial Group Random Design. The first factor is artificial Defoliation including no defoliation, Defoliation at 30 dap (day after planting) , and Defoliation at 60 dap. The second factor is disbudding including no disbudding, disbudding at 60 dap, and disbudding at 90 dap. The results demonstrated that the interaction between artificial Defoliation and disbudding significantly affected flower stalk weight but did not affect other variables. The treatment of leaf defoliation had significant to very significant effects on all observed variables, except for the weight of flower stalks, which was unaffected. At the same time, the disbudding treatment significantly affects all observed variables. The interaction between leaf defoliation at 30 dap and disbudding at 60 dap resulted in the heaviest average flower stalk weight of 93.58 grams. Artificial Defoliation at 30 dap increased the yield of economically viable fresh flower weight by 8.09 percent compared to when Defoliation was not performed. The 60 dap Disbudding treatment increased the yield of fresh flower weight by 9.25% when compared to the control.

Abstract

To enhance the intensity of chrysanthemum cultivation across different regions, further investigation is required regarding implementing suitable technology. This technology should be developed using local resources specific to chrysanthemum flowers to enhance their quality and value. Additionally, it should leverage readily applicable resources that align with farmers' capabilities, ultimately leading to a substantial increase in income. This study aims to acquire diverse organic materials suitable for chrysanthemum production in specific locations to examine the impact of different dosages on enhancing quality outcomes. The research methodology employed in this study is a Nested Experiments approach with a Random Design of Factorial Groups. Three types of organic sources are commonly utilized, namely: 1. organic matter derived from rasamala leaf litter (S), and 2. Chrysanthemum harvest residue (P). The study focuses on the effects of Chrysanthemums (P) and hydroponic media residue (H) on different types of organic matter with varying doses. The doses are nested within the different sources of organic matter. The findings indicated that the application of different sources of organic matter did not have statistically significant effects on the investigated variables, except the blossom diameter (cm), which exhibited a significant impact. The impact of different doses on the organic matter of various types of leaf litter had a notable influence on all observed variables. Specifically, a dose of 15 tons ha-1 resulted in the highest yield of economic flowers, with a fresh weight of 89.93 g. This represented a 17.01% increase compared to the lowest yield observed at a dose of 5 tons ha-1, which yielded 74.63 g. The relationship between different doses of organic matter remaining from chrysanthemum harvest and various observed variables was statistically significant. Specifically, a dose of 6 tons ha-1 resulted in the highest fresh weight yield of economically valuable flowers, measuring 94.89 g. This yield was 19.89% higher than the lowest yield observed with a dose of 2 tons ha-1, which measured 76.02 g. The impact of different doses on various types of organic matter in hydroponic media does not substantially influence all observable variables except for blossom diameter, which demonstrates a notable effect.
