Abstract

The purpose of this study was to determine the dose of fine compost and husk charcoal, as a source of silica and its interactions in the cultivation of chrysanthemum. The research method used was the factorial randomized block design carried out in the field of a green house. Two factors were used in this study which are made up of fine compost consisting in 3 levels - 0.5, 1.0 and 1.5 tons ha-1, and husk charcoal, also in 3 levels - 100, 200 and 300 kg ha-1. The results showed that the fine compost treatment had a very significant effect, at P <0.01, on all the observed variables. In addition, the highest fresh weight of this economical flowers was 88.83g, produced by the treatment with 1.5 tons ha-1 dose of fine compost. Also, this resulted to an increase in yield by 23.04% compared to the fine compost with the lowest treatment dosage. Similarly, the treatment with husk charcoal had a significant effect, at P <0.05, on the maximum plant height, flower stem length, and flower diameter. It also had a very significant effect, at P <0.01, on the stem diameter, flower stem weight, and fresh weight of the economical flowers. The treatment of husk charcoal with a dose of 300 kg ha-1 produced the highest fresh weight of 80.78 g. This resulted in an increase in yield by 53.73% compared to the treatment with the lowest dosage. However, the interaction between the two treatments had no significant effect on all observed variables.
