Arbuscular Mycorrhizal Fertilization Of Corn (Zea mays L.) Cultivated on Ferrous Soil in Southern Benin

Abstract

The attainment of the millennium for development objectives require to improve the productivity of major cultures like maize (Zea mays L.). The present study aimed to assess the potential of Glomus cubens, Rhizophagus intraradices and Funneliformis mosseae to improve the productivity of corn cultivated on reddish ferrous soil in Southern Benin. A block of nine treatments with four repetition completely randomized was installed. Plant height and diameter and leaf area are growth parameters measured. Grain yield and endomycorrhizal infection were also evaluated. The best growths and grain yield (2.33 t/ha and 2.12 t/ha) were obtained respectively with the plants treated with R. intraradices + 50% of NPK and G. cubens + 50% of NPK compared to the control plants (1.48 t/ha). Moreover, the great frequencies of mycorhization (44% and 32.25% were observed respectively on the plants treated with G. cubens + 50% of NPK and R. intraradices + 50% NPK. These results show that the respective combination of these two Arbuscular Mycorrhizal Fungi with 50% NPK can increase of 50% the seeds yield of corn compared to the seeds yield obtained with the control plants. In addition, G. Cubens and R. intraradices are active in the colonization of maize roots. Use of R. Intraradices or G. cubens in combination with 50% of NPK help to increase the corn productivity and to reduce of half the chemical fertilizer commonly used by corn farmers at Southern Benin.

Effect of Phosphorus and Arbuscular Mycorrhizal Fungi (AMF) Inoculation on Growth and Productivity of Maize (Zea mays L.) in a Tropical Ferralsol

“…Fertilization with 30 kg P2O5 ha -1 seemed to be sufficient to improve the nutritional status of the Ferralsol used as substrate for this experiment, compared to the dose of 60 kg P2O5 ha -1 which is low cost effectiveness. These results are nearing those found by Aguegue et al (2017) in Ferralsol in southern Benin, indicating that Glomus cubens species combined to a half dose of chemical fertilizers of NPK (7.5 P2O5 kg ha -1 ) allow to get an equivalent production of maize to that obtained using the recommended dose of NPK (15 P2O5 kg ha -1 ) alone. The AMF inoculum alone given cobs well filled with grains, thus much better than plants of the control (without phosphorus neither AMF inoculum) given cobs without grains.…”

“…The same average was obtained for plant height, leaves number and chlorophyll rate in leaves especially on treatments inoculated and fertilized with 30 or 60 kg P2O5 ha -1 . This joins the allegations of Davies and Linderman (1990) and Aguegue et al (2017) showing that the only micro-doses of chemical fertilizers (half of the crop demand) are sufficient to promote plant growth when AMF have been applied. Munir et al (2003) also showed that the addition of phosphorus decreases the mycorrhizal symbiosis because the plant's growth depends on the chemical fertilizer.…”

Impact of native arbuscular mycorrhizal fungi based fertilizers on to increase maize productivity in North Benin

“…These results agree with those observed by Bulakali et al (2000), who showed in their study that mycorrhizal fungi had a beneficial effect on the growth in diameter at the collar of corn plants. The same observations were made by Aguegue et al (2017), who showed that the inoculation of corn seeds by mycorhizal fungi had a beneficial effect on the diameter at the collar of the treated plants compared to the control. Previous studies have shown that the presence of mycorrhizal fungi stimulate the growth of the leaf surface of corn plants (Kothari et al, 1990).…”

Diversity of arbuscular mycorrhizal fungi associated to Sorghum (Sorghum bicolor L. Moench) in soils of Sikasso region (Mali)

“…The genus Glomus is the most represented in all sites with 15 morphotypes (65%). Such a result has been noted in different natural and agro-ecological environments in West Africa as well as in Ivory Coast (Anguiby et al, 2019), in Togo (Gnamkoulamba et al, 2018), in Benin (Aguegue et al, 2017), in Senegal (Diop et al, 2015), and in India (Ajaz et al, 2017). Indeed, it has been reported that the genus Glomus predominates in terms of presence in ecosystems due to its adaptability and stability in tropical environments and various conditions (Lenoir et al, 2016b;Bencherif et al, 2015).…”
