Yield performance of Liberica coffee clones on peat soil

M. Muhamad Ghawas

Abstract

Significant differences in yield and other parameters were obtained among 10 Liberica coffee clones evaluated on peat soil. Three top clones, namely MCL 21, MCL 26 and MCL 45, gave mean green bean yields of 1.47, 1.82 and 1.64 t/ha equivalent to fresh berry yields of 16.3, 18.2 and 20.1 t/ha respectively. Their mean green bean yield of 1.64 t/ha was about 66% higher than the yield of check plants (randomly selected open-pollinated seedlings). This value was, however, about 24% lower when cross-compared with the same set of clones on mineral soil while their respective fresh berry and green bean weights were about 11.7% and 3.3% heavier.
