Agriculture in Garut Regency, as a center for food and horticultural production, faces challenges due to declining soil fertility resulting from fertilizer practices that are not yet fully based on site-specific conditions. This study aims to interpret soil analysis results to determine soil fertility status and develop site-specific integrated nutrient management recommendations to improve fertilizer efficiency and ensure the sustainability of agricultural systems. The research was conducted on agricultural land in Sukamaju Village (Cilawu Subdistrict) and Cikandang Village (Cikajang Subdistrict), Garut Regency. Soil samples were purposively collected from a depth of 0–30 cm during October 2025. Soil analyses included pH, organic carbon, P HCl 25%, K HCl 25%, CEC, and base saturation to support site-specific fertility assessment and nutrient management planning. Soil chemical analysis in Sukamaju Village (Cilawu Subdistrict) showed a pH of 8,2 and organic carbon content of 4.73%. The P₂O₅ HCl 25% value was recorded at 91,20 mg.100 g-1, K₂O HCl 25% at 52,15 mg.100 g-1, CEC at 41,30 cmol.kg-1, and base saturation at 63,12%, indicating a high soil fertility status. Meanwhile, soil analysis in Cikandang Village (Cikajang Subdistrict) revealed a pH of 7, soil organic carbon of 5,58%, P₂O₅ HCl 25% of 99,53 mg.100 g-1, K₂O HCl 25% of 52,15 mg.100 g-1, CEC of 47,85 cmol.kg-1, and base saturation of 25,16%, indicating a low fertility status. Fertility maintenance strategies are recommended for high status soils, while nutrient balance improvement particularly for base cations and potassium is advised for low fertility soils.

Abstract. Nafi’ah HH, Fajarfika R, Fatimah R, Maulana H, Yoel A. 2025. Comparison of soil microbial composition and fertility in rhizosphere of healthy and Fusarium wilt-affected sweet potato plants. Biodiversitas 26: 941-950. Fusarium wilt is a significant disease impacting sweet potato plants, primarily affecting the stem and inhibiting optimal growth. The severity of the disease is hypothesized to be influenced by soil microbial composition and fertility. Therefore, this research aimed to compare the microbial composition and soil fertility parameters in the rhizosphere of healthy sweet potato plants and those infected with Fusarium wilt. The hypothesis posited that these two plant groups had significant differences in microbial composition and soil fertility. The method used was a Cross-Sectional Survey, a robust approach that involved data collection obtained through observation and soil sampling. Soil samples were obtained from Kuningan and Garut Regencies. Microbial diversity and abundance were analyzed using targeted quantification techniques, including the Total Plate Count method on selective media. Parameters of soil fertility, such as pH, organic matter content, and nutrient concentrations, were also evaluated. The results showed significant distinctions in microbial composition, with diseased plants exhibiting a higher microbial population dominated by beneficial microbes, such as Phosphate-Solubilizing Bacteria (PSB) and nitrogen-fixing bacteria. A negative correlation was observed between Fusarium fungi and PSB. Additionally, differences in soil fertility characteristics were evident between the two locations. This research provided a better understanding of the microbial population in sweet potato plants and a foundation for developing more effective strategies to manage Fusarium wilt.

Rice (Oryza sativa L.) is a major staple food commodity in Indonesia; however, its productivity often declines due to weed competition, one of which is Ludwigia octovalvis, commonly found in flooded paddy fields. Weed control through weeding practices and the application of appropriate cultivation systems is an important factor in improving rice growth and yield. This study aimed to determine the effects of weeding frequency and cultivation systems on the presence of Ludwigia octovalvis, as well as on the growth and yield of lowland rice. The research was conducted from July to October 2024 using an experimental method with a split-plot design. Conventional cultivation and no-tillage (NT/TOT) systems were used as main plots, while weeding frequency served as subplots, consisting of no weeding (P0), one weeding (P1), two weedings (P2), and three weedings (P3). The results showed that Ludwigia octovalvis began to appear at 60 days after transplanting and did not exhibit significant differences among treatments. The cultivation system and weeding frequency had no significant effect on plant height and tiller number at the early growth stage; however, treatment interactions significantly affected the number of productive tillers. The weight of harvested dry grain did not differ significantly among treatments. Therefore, weeding frequency plays an important role during the vegetative phase, whereas the final rice yield is more strongly influenced by environmental factors and integrated crop management.
