The Effects of Tea Wastes Prepared Using Different Composting Methods on the Seedling Growth and Selected Biochemical Properties of Maize (Zea mays var. indurata)

Food Science &Nutrition, Volume 13, Issue 8, August 2025.
This study investigates the effects of tea‐waste‐based composts enriched with various organic fertilizers on the seedling growth and biochemical responses of local maize genotypes. Compost mixtures, especially those containing chicken manure and vermicompost, significantly enhanced plant development and antioxidant activity.

Confrontations of the Pathogenic Fungus Colletotrichum graminicola With a Biocontrol Bacterium or a Ubiquitous Fungus Trigger Synthesis of Secondary Metabolites With Lead Structures of Synthetic Fungicides

Environmental Microbiology, Volume 27, Issue 7, July 2025.
Introduction of biocontrol agents to agricultural environments creates microbial confrontations. In confrontations between a fungal maize pathogen and a biocontrol bacterium or a ubiquitous fungus, novel compounds with similarity to synthetic fungicides and substances putatively toxic to humans are formed, questioning consumer safety of biological ...

Long‐term cropping system and manure effects on soil health parameters and associated soil‐borne pathogens

Soil Science Society of America Journal, Volume 89, Issue 3, May/June 2025.
Abstract Soil‐borne pathogens reduce the performance of key food crops in sub‐Saharan Africa. Diversified cropping and nutrient management can enhance soil and plant health, limiting pathogen damage. To examine how management and soil health changes influence soil‐borne pathogens, we leveraged an 18‐year field trial in western Kenya, evaluating ...
