ABSTRACT

Lantana camara L. which is called tembelekan by Indonesian people, is a shrub plant having wide ecological tolerances that can be found in varied habitats and shows a strong suppressive effect on a variety of crop species. In order to determine whether the chilli plants resistant to L.camara allelopathy, the tembelekan leaf extract was tested against the growth of red chilli (Capsicum annuum). By using completely randomized design, 25 red chilli plants were grouped into five consist of 5 plants each. Each plant was grown individually in a poly bag containing mixture of soil and compost in a ratio of 2:1. Group 1 is the chillies given 0% (v/v) L.camara leaf extract as the control. Group 2, 3, 4 and 5 are the plants treated with extract at the concentration of 25%, 50%, 75% and 100% respectively. After treatment for one week the chillies are harvested and all the study parameters namely plant height, fresh and dry weight, and concentration of chlorophyll were assessed. The results showed, plant height and fresh weight of chillies significantly decreased by the extract of 100%. Likewise, the content of chlorophyll b and total chlorophyll lowered significantly by aqueous leaf extract of tembelekan. In conclussion it can be suggested that aqueous extract of L.camara possess suppressive effects against the growth of red chilli.
