Abstract

The effects of selective pruning and non-pruning on "Fence" and "T" trellis systems, were evaluated over a two year period in the Commonwealth of Dominica. The "T" trellis gave higher fresh weight yields 3,511 and 6,916kg/ha in year I and 2, as compared to the wFence"-trellis which gave yields of I, 170 and 3,830 kg/ha for years 1 and 2 respectively. The nonpruned treatments gave higher yields i.e. 2,660 and 5,958 kg/ha when compared with the pruned treatments 1,596 and 4,682 kg/ha for years one and two respectively. Economic evaluation of the different trellis systems and pruning treatments, indicated that the "T"-trellis with the non-pruned treatments gave the highest returns EC$7 ,235 /ha (US$2,680) and EC$8,913/ha (US$330/ha) when sold to the processor and huckster respectively, over the two year period. Correlations between fresh weight and pulp weight were (r=0.945) in year one.
