Popis: One of the allelopathic uses is the application of sorghum water extract for weed control. Drought-shaped abiotic stress plays an important role in the plant contribution of allelopathy. This study aimed to examine the inhibition of sorghum water extracts grown in swampland with different irrigation patterns. The study employed a randomized complete block designed with two factors. The first factor was irrigation patterns, i.e., four weeks of dry and saturated water, alternating weekly saturated and dry water for four weeks, and alternating weekly dry and saturated water for four weeks. The second factor was water extract concentration, consisting of 0%, 2.5%, 5%, 7.5 % and 10%. Dry Ultisol was assigned as a control treatment. The bioassay procedure was set up with 25 sorghum seeds per petri dish. Each petri dish was solved and incubated for four days with a 10 ml sorghum water extract from each of the above treatments. The results showed the highest germination inhibition levels were in the interaction between the dry patterns (dry swampland and dry Ultisol) at 7.5% of water extraction. Sorghum extract, grown in dry swampland, is a potential for good bioherbicide production.
