- Abstract
This study aimed to determine the optimal fertilization conditions for perennial cranberry. The effects of fertilizer with low, medium, or high nutrient levels, supplied in solid or liquid form and with or without humic acid (HA) on cranberry were determined in a field experiment. The number of erect stems, fruit diameter, number of fruit set, 100-grain weight, and yield increased as the nutrient supply level increased from nitrogen-phosphorous-potassium (NPK) 3.30 kg/667 m² (low) to NPK 6.00 kg/667 m² (medium) to NPK 9.90 kg/667 m² (high). At the medium nutrient level, fruit diameter, fruit set, 100-grain weight, and yield were significantly higher in the liquid fertilizer treatments than in the solid fertilizer treatments. A compound fertilizer consisting of HA and NPK was better than inorganic NPK fertilizer. The addition of HA to solid fertilizer significantly increased fruit diameter, fruit set, and fruit yield; and the addition of HA to liquid fertilizer significantly increased fruit set. Considering fertilizer costs and the health of the soil ecological environment, NPK 6.00 kg + 4 kg HA/667 m² solid or liquid fertilizer is recommended for cranberry plants cultivated on a large scale.
