The objective of our study was to evaluate the promoted effects of three arbuscular
mycorrhizal fungi (AMF) on maize growth and yield on ferruginous soil in center of
Benin. The maize variety used was EVDT 97 STR C1. The maize seeds were
inoculated with each of three arbuscular mycorrhizal fungi (Glomus intraradices,
Funneliformis mosseae and Rhizophagus cubens) combined with or not to mineral fertilizer
dose recommended (50% of NPK). The experimental device was a completely
randomized random block of nine treatments with four repetitions. The data collected
were related to growth (height, diameter and leaf area), yield (biomass and grain yield),
mycorrhization (frequency, intensity and number of spores) and NPK content. The
maximum height, best seeds yield and larger leaf surface are obtained with maize plants
treated with R. intraradices combined with 50% of NPK respectively surpassing of
17.44%, 38.14%, 45.99% the values obtained with the controls plants. G. cubens
combined with 50% of NPK was induced an increase of diameter (6.50%), dry aerial
biomass (32.86%) and dry ground biomass (94.73%) compared to the control. G. cubens
only has led to the best frequency (41.25%), intensity of mycorrhization (6.07%) and a
high number of spore (1.81 spores/g soil). These results show the potential of these
arbuscular mycorrhizal fungi to improve the maize productivity on ferruginous soil in
center of Benin. |
