Résumé de la publication

The growth and grain yield of maize (Zea mays), variety 2000 SYN EE-W were assessed in response to combined inoculation of native arbusular mycorrhizal fungus (AMF) Rhizophagus intraradices with NPK fertilizer in rhizosphere of ferruginous soil of Benin. The experimental design was a randomized complete block of three treatments (CTL = Peasant Practice (without AMF, with mineral fertilizers); Ri½NPK = R. intraradices + 50%N15P15K15; NPK = 100% N15P15K15) with three repetitions. Each elementary plot was 4m length and 3.2m width. After opening a seed hole, two maize seeds previously coated or not with Rhizophagus intraradices strains the day before were put into the hole. Seeding was done by keeping a distance of 0.80m x 0.40m and a density of 31.250plants/ha. The maximum heights, larger diameters and leaf area, the highest dry aerial and underground dry biomass of plants, including the best yield in maize seeds were recorded with R. intraradices treatment combined with 50% of NPK with respective increases of 36.80%, 82.89%, 88.73%, 91.74%, 92.22% and 38.14% compared to the values obtained with Peasant practices. R. intraradices produced 2 spores/g of soil and hold averages of 51.67% and 6.17% respectively for mycorrhization frequency and intensity. These results portend the use of this strain as an alternative solution to increase the productivity of maize in Benin.
