The purpose of this study was to determine differences in allelopathic characteristictics between fresh leaf extract and dried red guava leaves (Psidium guajava L.) on the growth of curly red chili sprouts (Capsicum annuum L.). The research was conducted from November to December 2018 in the Botanical Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung; This study uses more completely randomized design (CRD) with the main factor being fresh leaf exstract and dried leaves of red guava (Psidium guajava L.). There are 5 concentration used, control (0% v / v), fresh leaves (1% v / v, 3% v / v), and dried leaves (1% w / v, 3% w / v). Each treatment consisted of 5 replicates. Homogenesis variance was determined by the Levene test at the 5% level. Analysis of variance and Honestly Significant Difference test (BNJ) was carried out at the 5% level. The results showed that the fresh leaf extract and dried leaves significantly affected length of sprout buds, and chlorophyll b. However, it did not significantly affect on fresh weight (roots, shoots, sprouts), and the dry weight (roots, shoots, sprouts), root shoot ratio, relative water content, chlorophyll a and total chlorophyll. Dried leaf extract was more significant in inhibiting the growth of curly red chili sprouts at high concentration of 3% compared to fresh leaf extract at the same concentration. However, fresh leaf extract at a concentration of 3%, slightly increased the ratio of chlorophyll b to chlorophyll a by as much as 3% of the control. While, dry leaf extract at a concentration of 3% was significant in inhibiting the growth of curly red chili sprouts and slightly lowering the shoot budding ratio and relative water content in curly red chili sprouts.
