Abstract: | Weeds are the main plant competitors. Some types of weeds are also places for pests and plant diseases to live. Spinach thorn is one type of weed that is often found in cultivated plants. Weed control is often done by using herbicides. The use of herbicides in the long term can have a negative impact on the environment. An alternative effort to avoid this impact is to utilize allelochemical compounds found in certain plant parts as growth inhibitors and do not cause residues for the environment. Lime leaf is one of the plants that contains allelochemical compounds, namely flavonoids and saponins that play a role in inhibiting the process of weed growth. The research was conducted from January to June 2021, at the Pests and Plant Disease Laboratory. This study used a single factor Completely Randomized Design (CRD), namely the administration of lime leaf extract with 5 levels of concentration with each treatment 5 times, 0% concentration, concentration of 20%, 30% concentration, concentration of 40% and 50% concentration. Observed parameters are, namely height, number of leaves, dry weight and intensity of spinach thorn weed poisoning. Data were analyzed by analysis of variance ANOVA to determine the effect of treatment and tested with Duncan's Multiple Range Test (DMRT) at a 5% confidence level to compare treatments. The application of lime leaf extract (Citrus aurantifolia C.) can affect all observed parameters. The most effective concentration of lime leaf extract to inhibit the growth of spinach thorn weed was concentration of 50% causing death with result of the height is 15.9 cm, number of leaves 9 leaves, dry weight 2.05 gram and poisoning rate of 100%. |
