Excessive potassium fertilizer intensifies fruit cracking in litchi

Nutrient management for litchi
Litchi fruit cracking

Potassium (K) is most important in producing high yield and quality of litchi fruit. However, overdose of fertilizer K can induce fruit cracking when application ratio of fertilizer N : K2O was far smaller than 1:1. High rates of fertilizer can interfere with calcium metabolism, depress calcium concentration in fruit tissues and induce severe fruit cracking. Thus, good nutrient balance in litchi production is most crucial.
