Production and post-harvest quality of mini-watermelon crop under irrigation management strategies and potassium fertilization

HIGHLIGHTS: Despite the deleterious effect of salinity on the diameter of mini-watermelon fruits, their appea-rance was not negatively affected. Salt stress in the flowering and maturation stages does not compromise the production of mini-watermelon. Water salinity of 4.0 dS m-1 reduces soluble solids and ascorbic acid in fruits when plants are fertilized with 150 mg K2O kg-1 of soil.
