Research ArticleOpen accessIn the abstractPhosphorus Availability Modulates Bradyrhizobium japonicum’s Impact on Soil Micribial Biomass and Soybean (Glycine max (L.) Merrill) Yield in Lubumbashi Tropical SoilsBen Tshibuyi Kasu-Bandi et al.Tropical soils in sub-Saharan Africa exhibit low fertility, high acidity, and limited Phosphorus (P) availability, a key nutrient for agricultural productivity and the sustainability of cropping systems. This deficiency, exacerbated by the strong fixation of P in acidic soils, not only limits plant growth but also the efficiency of the nitrogen-fixing symbiosis between soybeans (Glycine max (L.) Merrill) and Bradyrhizobium … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 13 May 2026 · 1,980 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Sweet Corn Growth and Yield through the Integrated Application of Bioneensis Biofertilizer and Rice Husk BiocharSumihar Hutapea, Saipul Sihotang, Adi Fathul Qohar et al.Sweet corn is an essential agricultural product in Indonesia and contributes to national food security. Consequently, numerous strategies can be implemented to increase the yield of sweet corn, such as intensified fertilization. While organic fertilizers like biofertilizers and biochar have shown potential to enhance crop growth, their combined effects on sweet corn, particularly under Indonesian conditions, are understudied. This study … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 6 Feb 2026 · 1,929 accessesView PDFCite
