In a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) research study, …
Foliar Potassium and Boron Can Improve Mandarin Yield and Quality
By Tripti Vashisth and Faisal Shahzad Mandarin production has been increasing in Florida since some mandarin varieties can potentially withstand HLB better than sweet orange varieties.
