| Abstract:
A two year trial was set up to test the viability of single-cycle cultivation using hardened vitro plants of Grande Naine (pseudostem height &appeq;45 cm and &appeq;4.5 cm thickness), at a spacing of 5.0 m x 2.5 m with 3 plants per hole (2,400 plants/ha). Twelve months after the beginning of the trial, a new planting was inserted between the existing plants, with the same spatial arrangement. The first crop was harvested 14 months after planting and the second 12 months later, thus effectively obtaining an annual crop; yields were 73.1 ton/ha and 77.7 ton/ha, respectively, with more of 90% of the fruit qualified as Extra. A comparative study of harvest date and yield was made between the three plants of each hole. Results showed significant differences due to orientation although absolute differences were slight | |
