On-station and on-farm groundnut research was carried out in
Sikonge district, Tanzania, to evaluate groundnut varieties
for yield under researcher and farmer managed conditions and
assess farmer preferences. On-station trial was laid in a
randomized complete block design with three replications.
Five varieties Johari, Pendo, Nyota, Sawia
and Mamboleo were planted on 25 m2
plots at spacing of 0.9 x 0.15 m. Twelve farmers
were involved in conducting on-farm trials with each farmer
as a replicate. Participatory farmers evaluation and
stability analysis were done. Both
on-station and on-farm trials revealed high yield among
varieties with Pendo (1444 kgha-1) and Johari
(1163 kgha-1) out yielding other varieties which
were also ranked by farmers and researchers as the most
preferred genotypes. The
genotypes and environments sum of squares accounted
for the most of the variability by contributing 38.10 and
32.99% for genotypes and environments respectively. Mamboleo
and Sawia varieties showed high G X E stability. Farmers
and researchers ranked Pendo and Johari as the best
varieties.
Key words:
Arachis hypogaea, participatory farmers’ evaluation,
groundnuts, stability analysis. |
