Development of Plant-Based Foliar Fertilizers from Tithonia diversifolia and Eichhornia crassipes to Enhance Growth of Irish Potato (Solanum tuberosum L.)
This study demonstrates that a blended foliar fertilizer derived from *Tithonia diversifolia* and *Eichhornia crassipes* ashes significantly enhances the growth of Irish potatoes in Kenyan field conditions, offering a sustainable and locally available alternative to synthetic inputs.
