Abstract
Curcuma ‘Golden Reign’ is a beautiful gigantic tropical flower.
It can be utilized in various ways such as landscaping plants, potted plants and cut flower.
However, there is limited data about nutrient deficiency symptoms in ornamental curcuma.
Therefore, the purpose of this experiment was to study the effect of the lack of some macro elements and micro elements on growth and development of curcuma plants.
The curcuma rhizomes were grown in a hydroponics system.
The experimental design was completely randomized design (CRD) with 3 replications per treatment and, 2 plants per replication with 14 fertilizer treatments, T1: plants were supplied with complete solution as control treatment (Hoagland’s solution), and T2-T14, plants were supplied with deficiency solutions of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium(Mg), sulfur (S), iron (Fe), boron (B), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo) and deionized water, respectively.
The results showed that at 18 weeks after planting, potassium deficiency treatment showed plant height lower than the control treatment.
Moreover, the old leaves were burned, chlorophyll content in old leaves and young leaves were 26.50 and 31.20 SPAD unit, respectively.
Magnesium deficiency treatment resulted in yellow color of old leaves and interveinal chlorosis.
The shortest flower length was obtained from the boron deficiency treatment.
