Genetic analysis of extra-early yellow and orange quality protein maize (Zea mays L.) inbread lines under low nitrogen and Striga stresses por Abu, P.

“…The hybrids were screened under low-N conditions (30 kg ha-1), Striga-infestation and optimal management conditions in Ghana and Nigeria in 2018. Significant general combining ability (GCA) and specific combining ability (SCA) effects were observed for grain yield and most agronomically important traits in the low-N, Striga-infested and optimal management conditions. …”

Effects of potassium and magnesium on cassava vegetative and root yield por Sanginga, A.D.

“…A 2-cropping season experiment was conducted in a randomized complete block design (RCBD) to evaluate cassava variety TME419 at different combinations of K and Mg in Ibadan (7°2916N, 3.5302° E), southern Nigeria. Fertilizer treatments included 0, 90 and 180 kg ha-1 of K, 0 and 15.5 kg ha-1 of Mg and 20.5 kg ha-1 sulphur (S) to account for the S in Kieserite (MgSO4) combined as follows: control (F0), 90 K kg ha−1 (F1), 180 K kg ha−1 (F2), 0 K:15.5 Mg:20.5 S (F0+Mg1), 90 K:15.5 Mg:20.5 S kg ha−1 (F1+Mg1), 180 K:15.5 Mg:20.5 S kg ha−1 (F2+Mg1), 90 K:20.5 S kg ha−1 (F1-Mg+S) and 180 K:20.5 S kg ha−1 (F2-Mg+S). …”

Analysis of yam yields using the additive main effects and multiplicative interaction (AMMI) model por Egesi, Chiedozie N., Asiedu, Robert

“…In this study, the AMMI model was used with the objective of assessing yam genotypes yield, selecting stable genotypes, and investigating G x E effects from trials conducted for two years at five locations in Nigeria. The effects of environments, genotypes and genotype-by-environment interaction (G x E) were highly significant (P<0.001). …”
