Potatoes are a potential food crop to be cultivated because they contain carbohydrates, protein, minerals and vitaminsand are able to meet people’s demand for food supply. Demand for potatoes comes from household consumption, restaurant businesses and potato based indrustries. Apart from providing food needs, potato cultivation can support the community’s economy. Therefore, potato cultivation needs to continue to be carried out optimally. One of the problems with potato cultivation is the decreasing quality of the soil due to the tendency tu use inorganic fertilizers so that soil fertility decreases. The solution implemented is the application of organic materials to improve soil quality and provide plant nutrients. The purpose of writing this article is to determine the effect to appliying organic cow dung fertilizer on changes in soil quality and potato plant growth. The method used in this research is a qualitative method with literature study techniques.

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.
