YIELD AND TREE GIRTH VARIABILITY IN SOME COLA NITIDA POPULATIONS

The yields of Cola nitida trees in plot BXI, Tafo, planted in 1967 are reported.
In 272 trees of Oyoko White, 52% fruited in 1973–’74 and 39% during 1974–’75. In 262 trees of Oyoko Red, 38% fruited during 1973–’74 and 33% in 1974–’75.

Yield was very variable in both populations, and low yielders predominated.
In Oyoko White, 20% of the bearing trees produced 39% of the total yield and in Oyoko Red, 20% of the bearing trees produced 41% of the yield.

The individually recorded trees of three populations in Cola Plot 1, Bunso, planted in 1968, also showed great variability. 29, 45 and 37% of the trees fruited in 1973–’74 in Bunso White, Kumasi White and Kade Red, respectively.
Much variability in tree girth occurred.
