Influence of substrate, cutting length, and hormone treatment on rooting ability of Dacryodes crassifora in the nursery

The study was carried out to determine the rooting ability of Dacryodes crassiflora cuttings in the nursery. A three way factorial treatment structure with substrates (3 levels), hormonal treatment (2 levels) and cutting length (2 levels) was used to assess the rooting ability of each cutting. The trial set up as a complete randomised blocks design with 3 replications. For each treatment combination, 8 cuttings were assessed per replication making a total of 288 cuttings used in the trial. Cutting status (rooted or not, died) were recorded weekly from the 4th to the 11th week after setting. For each rooted cutting, the number of roots was determined. Data collected were compiled in an Excel file and the rooting rate computed as a number of cuttings that have effectively rooted divided by the total number of cutting used in the trial were detemined and compared amont treatment combinations.
