Abstract A greenhouse experiment was conducted to investigate the single and combined effects of different arbuscular mycorrhizal fungi (AMF) and bioformulated Paecilomyces lilacinus against M. incognita race 1 on tomato. Dysteric Cambisol soil was used. The experiment took place in Calabar, Cross River State, Nigeria. The experiment was laid out as a 3x6 factorial in a completely randomized design (CRD) with three replications. Three applications of the bionematicide were combined with five species of AMF plus an uninoculated control. The results indicated that AMF species differed significantly (p ≤ 0.05) in their efficacy of gall and egg mass inhibition, tomato root colonization rate as well as growth and fresh fruit yield enhancement. Glomus etunicatum and G. deserticola were the most efficient species. Two applications of the bionematicide more significantly (p ≤ 0.05) reduced galling and egg production than a single application. Individual combinations of two AMF (G. etunicatum and G. deserticola) with a double application of the bionematicide, resulted in the greatest gall and egg mass inhibition and consequently the greatest growth and fresh fruit yield enhancement.

Strawberry Cultivars

The use of arbuscular mycorrhizal fungi (AMF) is a strategy to increase the absorption of nutrients by plants, stimulate the plant defense system, and promote the synthesis of bioactive compounds. In addition, AMF can reduce production costs and improve the agricultural and environmental sustainability of farming systems. The objective of this study is to evaluate the effect of AMF on production and physiological parameters of strawberry cultivars. The cultivars Camarosa, Aromas, Camino Real, Monterrey, Portola, San Andreas, and Albion were evaluated in the year 2016, and Camarosa, Camino Real, Monterrey, and Albion were analyzed in the year 2017. These cultivars were grown either with or without AMF. The analyzed production variables were the total number of fruits and fruit yield and weight. Gas exchange and leaf area were also determined in 2017. Fruit yield in treated and control plants was assessed in the two study years. AMF inoculation augmented the leaf area in all cultivars except for Monterrey, photosynthetic performance in the cultivars Camarosa and Camino Real, and the transpiration rate in the cultivar Camarosa. These results indicate that AMF improve agronomic and physiological characteristics of strawberry cultivars.
