Abstract

The objective of this research was to study the optimal concentrations of calcium oxide for growth and sensory quality of Linharn (Launaea sarmentosa). The experimental design was completely randomized design (CRD) with 1 pot/replications and 15 replications. Planting the Linharn in the growing media (sea sand : coconut dust : cow dung, 1 : 1 : 1) and spray with calcium oxide at concentrations of 0, 100, 300, 500 and 1,000 mg/L. The results showed that the Linharn sprayed with calcium oxide 300 mg/L promoted the growth of the number of leaf, leaf width, runner length and number of runner plant and fresh weight, as well as sensory quality of the friableness, greenness of leaf and foul-smelling, with a significant difference (p < 0.01) compared to the control (non-sprayed calcium oxide Linharn). For the bitterness of the Linharn, it had the same level of bitterness as compared to the Linharn grown near the coast. The statistically significant difference (p < 0.05) of bitterness was observed between sprayed and non-sprayed calcium oxide.
