How many seednuts to plant one hectare?

By R. Bourdeix, 2017.

Taking into account:
  • the germination percentage (80% is the international standard except for Aromatic Green Dwarf (60%)
  • eliminations at the seed bed stage (12 %), (abnormal, latest germination, Dwarfs when planting DwarfxTall hybrids)
  • selection in the nursery (15%)
  • the fact that about 5% of the palms need to be replaced during the first and second year after planting
The following table gives the quantity of seednuts to prepare according to the type of varieties planted. Selection is an essential stage and only the strict application of the rules described in these guidelines can guarantee the greatest precocity an highest profitability to the plantation. As planting a young a coconut represents an investment in more than 30 years of exploitation, it is better to conduct severe elimination in the seddbed and nursery rather than to keep on from 10 to 20 p. 100 of backward, stunted, unproductive or barely productive trees throughout the plantation’s life.
