Ten elite genotypes in total (of groundnut, pigeon pea,
sorghum and pearl millet) and four local checks (one for each
crop) were used in the study to identify legume and cereal
genotypes of higher productivity in the varying potential
agro-ecologies. The experiments were established following
an incomplete randomized block design with two farmers
selected per sub agro-ecology as replications. Combined
analysis of variance over locations was carried out for grain
yield and yield components. The results showed significant
differences (P ≤ 0.05) among groundnut and pearl millet
genotypes tested for grain yield while for pigeon pea and
sorghum genotypes the differences were insignificant (P ≤
0.05). Genotype ICGV-SM 05650 of groundnut had the highest
grain yield of 2105.08 kg ha-1, whereas the lowest grain yield
of 1538.87 kg ha-1 was recorded in ICGV-SM 02724 in the high
potential agro-ecology. Pearl millet genotype IP 8774 ranked
highest in terms of yield performance (1049.4 kg ha-1) and the
local check had the lowest yield of 388.9 kg ha-1. Though non significant differences (P ≤ 0.05) among genotypes tested for
grain yield were observed in pigeon pea and sorghum
genotypes however, pigeon pea genotype ICEAP 00040 had a
slightly higher grain yield of 779.17 kg ha-1 and sorghum
genotype GAMBELLA 1107 outperformed the other
genotypes with grain yield of 1420.8 kg ha-1. Genotypes ICGV SM 05650, ICEAP 00040, GAMBELLA 1107 and IP8774 were
therefore recommended for deployment in these varying
potential agro-ecologies due to their superior performance in
terms of grain yield. |
