the influence of seed rhizome size on the growth, yield and economic return
of ginger to determine an optimum seed rhizome size. The experiment was
conducted for three years (1995-1997) at Tepi Agricultural Research Sub-center
using a locally grown ginger cultivar. It consisted of four different
weight and sizes of seed rhizomes which were grouped as small (R-4 g),
medium (R-8 g), large (R-16 g) and very large (R-32 g). The treatments
were arranged in Randomized Complete Block Design (RCBD) with four replications.
An increase in seed rhizome size significantly increased the major growth
and yield component parameters of ginger. Seed rhizome size also significantly
affected dry rhizome yield in all the 3 years that the largest seed rhizome
size (R-32 g) had significantly higher rhizome yield than the other treatments
in 1995 and 1996 and the small and medium size treatments in 1997. The
R-32 g treatment increased rhizome yield by 124, 152 and 55% over the
R-4 g treatment in 1995, 1996 (low rainfall year) and 1997 (high rainfall
year), respectively suggesting the importance of using larger seed rhizomes
under relatively lower than higher rainfall conditions. The R-32 g treatment
gave a Marginal Rate of Return (MRR) of 235% with the highest residual
indicating that using 32 g (>9.1 cm long) seed rhizomes is economically
profitable for ginger production in South Western Ethiopia.]]>Blay, E.T., E.Y. Danquah and G.
