Abstract

Allelopathy-based bioherbicides for drought-stressed sorghum plants are a concrete step towards sustainable agriculture. The aim was to identify the germination characteristics of sorghum seeds and flavonoid levels in their extracts at various levels of drought stress. Extract materials were prepared from June to August 2024 at Bengkulu University Greenhouse, Kandang Limun Village, Bengkulu City, and bioassay tests were conducted in August 2024 at Pematang Gubernur, Muara Bangkahulu, Bengkulu City. Flavonoid analysis was performed at the Integrated Research and Testing Laboratory (LPPT) of Gadjah Mada University in August 2024. This research used a completely randomized design (CRD) with one factor. One sorghum variety, Super 1, was planted with water stress treatment through watering patterns every day, every 2 days, every 3 days, every 4 days, and every 5 days. The experimental unit was a petri dish, and the experiment was repeated four times. The Petri dish bioassay method was applied in this experiment. Each petri dish was given 10 mL of aqueous extract, and 25 mung bean seeds were planted and incubated for three days. The results showed that the watering pattern achieved the highest flavonoid content every 4 days (4121.00 µg/g), and the second highest flavonoid content was Super 1 + every 5 days. The once every 5 days watering pattern achieved the highest sprout inhibition. The higher the level of stress, the higher the level of inhibition of seed germination, so it has the potential to be the best bioherbicide.

Abstract

The use of synthetic herbicides in agriculture raises many problems, including weed resistance, ecological damage, and health risks. To address these issues, plant-based biological herbicides have been introduced as a safer and more sustainable alternative. This study focuses on plants that exhibit allelopathy, including those that contain phenolic compounds, flavonoids, terpenoids, alkaloids, and tannins, which have the potential to be compact and phytotoxic to weeds through various mechanisms, including inhibiting germination, root growth, cell respiration, and photosynthesis, and disrupting hormonal balance. Therefore, various water-extraction techniques, such as soaking, boiling, and maceration, were studied to obtain the maximum amount of bioactive compounds. Plants that produce potent phytotoxic compounds, including Sorghum bicolor, Ageratum conyzoides, Chromolaena odorata, Mikania micrantha, Azadirachta indica, and Tagetes erecta, have been tested to contain active compounds that are effective in suppressing the growth of various weeds. Adaptation and development of bioherbicides made from water-extract compounds in the field of research, although promising, also face various challenges, including degradation of the active compounds, variations in raw materials, low extract concentrations, and the need for standardization in extraction methods and formulations. Therefore, characterization techniques for potentially allelopathic materials, more sophisticated formulations such as microencapsulation and nanoformulation, and investigation of potentially synergistic compounds between plant extracts and beneficial microorganisms are needed. This study confirms that plant water extracts have great potential as environmentally friendly weed-control solutions that support sustainable agricultural systems.
