- Abstract
Sorghum extract has an allelopathic potential to control weeds. Allelopathy is the suppression of a plant’s growth by a toxin released from a nearby plant of the same or another species. One factor determining plants’ contribution to releasing allelochemicals is abiotic stress, such as drought. This study aims to determine the efficacy of water extract of sorghum grown in different irrigation patterns cultivated in swamps at various concentrations. This study used a complete randomized block design consisting of two factors. The first factor was the irrigation pattern consisting of saturated water, dry, water-saturated-dry (with interval time one week), dry - water-saturated (with interval time one week), and dry. Sorghum was planted for four weeks in this irrigation pattern. The second factor was the allelopathic concentration, consisted 0%, 5%, 10%, 15%, 20% and 25%. Dry Ultisol soil was used as a control. The research was conducted using the Petri dish bioassay method. The sprout evaluation was carried out on 25 sorghum seeds, which were germinated in each Petri dish. A total of 10 ml of extract from each treatment was added to each Petri dish and then incubated for four days. The experiment results showed that sorghum extract from a plant grown in dry swamplands at a concentration of 5% to 10% resulted in the highest sprout inhibition. Therefore, the sorghum extract from dry swamps cultivation has the potential as a bioherbicide.
