“…It is also better for drought tolerance. In many crops, it provides earlier flowering and higher grain yield [12,13]. Crops often fail to establish quickly and uniformly in the semi-arid tropics area, so plant populations decrease.…”

“…Ceci serait lié à l'appauvrissement croissant des sols en éléments minéraux majoritairement l'azote et le phosphore, d'où la nécessité de développer des méthodes permettant d'améliorer durablement la fertilité des sols afin d'accroitre le rendement de cette culture. Or il est bien établi que le sésame forme une symbiose avec les champignons mycorhiziens arbusculaires (Diouf et al, 2009;Diatta et al, 2013;Askari et al, 2019) alors que l'effet de la symbiose mycorhizienne sur la croissance et la production des plantes n'est plus à démontrer (Haro et al, 2012a;Diatta et al, 2013;Haougui et al, 2013;Haro et al, 2015;Haro et al, 2016a;Haro et al, 2016b;Haro et al, 2017;Askari et al, 2019). L'exploitation de cette symbiose serait une possibilité pour améliorer la productivité du sésame.…”

Au Burkina Faso, le sésame est essentiellement une culture de rente. Sa production augmente progressivement alors que son rendement baisse d’année en année. Ceci est lié à la pauvreté du sol en éléments minéraux tels que l’azote et le phosphore assimilable entrainant une augmentation des superficies emblavées pour cette culture et une utilisation des intrants chimiques de plus en plus grande. Or les intrants chimiques ont montré leurs limites dans leur utilisation. C’est ainsi que cette étude a été initiée afin de contribuer à l’amélioration de la production agricole durable. Dans cette étude le sésame a été cultivé en serre et inoculé avec deux inocula mycorhiziens indigènes. Les paramètres de croissance ont été mesurés à 30 et 60 jours après semis. La biomasse aérienne, racinaire et totale ont été évaluées à 60 jours après semis. Les résultats montrent une amélioration de la croissance en hauteur de 431,25%, taux de croissance relative en hauteur de 145,87%, diamètre au collet de 163,92%, biomasse aérienne de 102,9%, biomasse racinaire de 126,67% et de la biomasse totale de 110,1% par l’inoculation. Cette étude a montré des résultats prometteurs et mérite d’être approfondie par des essais aux champs.

English Title: Sesame (Sesamum indicum L.) response to mycorrhizal inoculation with native arbuscular mycorrhizal fungi to Burkina Faso In Burkina Faso, sesame is essentially a cash crop. Its production is gradually increasing while its yield decreases. This is linked to the soil poverty in mineral elements such as available nitrogen and phosphorus leading to an increase in the area sown for this crop and an increasing use of chemical inputs. However, chemical inputs have shown their limits in their use. This is how this study was initiated to help improve sustainable agricultural production. In this study, sesame was grown in greenhouse and inoculated with two inocula of native arbuscular mycorrhizal fungi (M1 and M2) from Burkina Faso. The growth parameters were measured at 30 and 60 days after sowing. Shoot, root and total biomass were assessed at 60 days after sowing. The results obtained show an improvement in height growth of 431.25%, the relative growth rate in height of 145.87%, the collar diameter of 163.92%, the aboveground biomass of 102.9%, root biomass of 126.67% and total biomass of 110.1% of plants inoculated with arbuscular mycorrhizal fungi compared to the inoculated control. This study has shown promising results and deserves to be deepened by field tests to assess the effect of this inoculation on sesame yield.Keywords: Sesame, mycorrhizal inoculation, arbuscular mycorrhizal fungi, Burkina Faso.

“…The most critical production input is water that significantly affects plant growth and crop production [8,9]; however, water deficit reduces drought stress [10]. Drought stress mainly leads to decreased plant growth [11] and photosynthetic production [12,13], nutritional disturbance, restriction of water absorption, and damage to the plasma membrane [14]. Grain yield of L. iberica and L. royleana plants decrease in severe drought stress due to the reduction of photosynthetic materials [14].…”

“…Improvement of nutrients such as P in soil and increasing root colonization via AMF can maintain optimal growth and water relations and, in contrast, enhance host plant resistance under drought stress [18]. Root colonization by mycorrhizal fungus is an alternative strategy to enhance plants' drought tolerance and increase water balance in drought conditions [12,24]. It has been reported that adding AMF inoculum in soil not only enhances root colonization and water use efficiency but also has an influence on increasing photosynthetic pigment and fatty acid synthesis under drought stress [12,18,25].…”

Background: Application nano iron chelate and AMF fertilizer can increase plants' tolerance against water deficit stress. The main objectives of the current study were to investigate the effect of arbuscular mycorrhizal fungi (AMF) and nano iron chelate fertilizer under drought stress on grain yield, leaf chlorophyll contents, root colonization, oil percentage, and fatty acids profile of Lallemantia species. The experiment was carried out as a factorial based on a complete randomized block design consisting of three factors of irrigation levels of 90 (I90), 60 (I60), and 30% (I30) depletion of available soil water (ASW)), fertilizer levels of control (no fertilizer), AMF inoculation, and nano iron chelate, and plant species of Lallemantia (L. iberica and L. royleana) at the Research Farm of College of Agriculture, Shahed University, Tehran, Iran, in 2018/2019. Results: The results showed that increasing water deficit stress significantly decreased the above traits while applying nano iron and AMF fertilizers significantly increased them across water treatments. AMF fertilizer inoculation significantly improved both species yield. Higher root colonization by AMF inoculation enhanced seed oil and fatty acids (palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, and Eicosenoic acid). In contrast, applying nano iron chelate by increasing chlorophyll content in any irrigation regime could enhance seed oil and some fatty acids such as palmitoleic acid. Conclusions: Water deficit stress and application of fertilizers had different effects on both species. L. iberica, compared to L. royleana, had the most tolerance to water deficit stress and the highest dependence on AMF inoculation. Overall, these results demonstrated that the application of AMF could improve major features of Lallemantia species under deficit irrigation conditions, especially at the I60 irrigation level.
