The study was carried out to assess how different fertilizers and their application cycles affected the development and productivity of coconut trees grown in embryos.
The experiment was conducted in an entirely randomized manner with five treatments performed continuously for three years on sap coconut at 5-year-old embryo-cultured trees in Tra Vinh province, Vietnam.
It was observed that 7-year-old embryo-cultured sap coconuts did not change in size and girth. The number of newly formed leaves ranged from 24.7 to 25.3 leaves/tree/year. The average number of newly formed inflorescences ranged from 16.1 to 18.5 inflorescences/tree/year. Fertilizers and their application time did not affect the fruits/bunch on embryo-cultured sap coconut trees. Fertilization of embryo-cultured sap coconut trees over 5 years old with 118 N-42 P2O5-54 K2O once a month recorded 72.3-93 fruits/tree/year and 7-year-old embryo-cultured sap coconuts recorded wax fruits/bunch ratio of 94-96%.
