Abstract
Thirty-eight varieties of groundnut(Arachis hypogea L.)
harvested approximately four months after planting date were
assessed for forage yield (FOYLD) leaf to stem ratio,
(LFST) , dry pod yield (DPYLD) , shelling (SHLG) and seed
yield (SEYLD). The chemical composition-crude protein (N x
6.25) and neutral detergent fibre (NDF) of forage, and rumen
degradation characteristics of leaf and stem portions were
also determined. There were significant differences (P<0.05)
among varieties in dry pod yield, seed yield, potential
degradability, rate of degradation and effective
degradability. Dry pod yield varied among varieties from
1457 kg/ha to 3980 kg/ha, while SEYLD was from 729 kg/ha to
2218 kg/ha. Forage yield varied from 2177 kg/ha to 7831
kg/ha. Leaf potential degradability (PD) varied from 678
g/kg to 914 g/kg dry matter (DM) while stem PD was from 538
g/kg to 702 g/kg DM. Both the leaf and stem fractions had
protein content above 7%, which would suffice for the
protein needs of cattle for maintenance. Varieties assessed
were recommended for the dual purpose needs of the farmer
with regards to seed and forage yields. Farmers who have a
bias for seed production are recommended to use M572 - 801,
ICGV 86222, RMP 12 and M554 - 76. These had seed yields from
2003 kg/ha to 2218 kg/ha. Varieties recommended for forage
production were M170 - 801, 2546 - 79, 42 - 85, and UGA 2.
The forage dry matter yields of these varieties varied from
6459 kg/ha to 7831 kg/ha of dry matter.
