Effect of Pre-Harvest Foliar Calcium and Silicon Fertilization on Pineapple Quality and Fruit Collapse Incidence

Pineapple can be affected by fruit collapse, a disease caused the bacterium Dickeya zeae. However, adequate fertilization increase fruit’s resistance to this illness. Therefore, impact of preharvest foliar calcium and silicon on pineapple quality collapse incidence was assessed in study. The experiment implemented split-plot design with two factors. first factor has terms inoculation (flower induction before harvest). second uses control three treatments, A (control: No fertilizers applied), B (Ca from 13 11 weeks harvest/from 6 harvest), C (Si D + Si Treatment gave best response. It had lowest (21.70%), highest ascorbic acid (71.64 mg/kg), elevated β-carotene (4.87 mg/kg) mineral content (Ca: 1851.10 mg/kg, Si: 1164.87 essentially under harvest term inoculation, which more harmful for fruit. In conclusion, mixed manage improve tolerance incidence, impacting positively
