Impact of mulch and fertilizer application on yield components, tuber quality and the nutrient uptake of selected potato cultivars under irrigated conditions

Ntuli, Jabulani (2024)

Integrated nutrient management (INM) in potato production is a promising mitigation strategy to reduce the nutrient-related yield gap. Potato yield and quality are limited in Limpopo by poor soil fertility. This problem ...
Impact of oncorhynchus mykiss, salmo trutta and clarias gariepinus on aquatic communities within Magoebaskloef Area, Limpopo Province, South Africa

Hlungwani, Hlulani Archebold (University of Limpopo, 2016)
