“…A. elongatum and F. arundinacea). This fact was already reported in some cereal crops (Smith and Smith 2011) and different genders of cultivated temperate grass species (Powell and Daniel 1978;Hall et al 1984;Grimoldi et al 2005;Covacevich and Echeverr ıa 2008) at different soil stressful conditions. It has been reported that many of the grassland species that form symbiosis with AMF show positive effects on plant biomass components (Hartnett and Wilson 2002;Hoeksema et al 2010).…”

Arbuscular mycorrhizal fungi (AMF) colonize the root systems of most natural grassland species and usually increase plant growth by enhancing nutrients provision. This effect on growth responses of cultivated forage grasses is scarcely known, particularly under nutritional deficit conditions. We examined total biomass production, aboveground and belowground biomass and tillering of three temperate and three tropical cultivated forage grasses. Seedlings of each species were inoculated with a mixture of mycorrhizal fungi and later grown for 5 months under nutritional deficit conditions. The mycorrhizal symbiosis promoted aboveground and belowground biomass production in five out of six grass species. Grass species differed in their mycorrhizal responsiveness: tropical grasses (Panicum coloratum cv. Klein = Brachiaria brizantha cv. Marandú > Paspalum dilatatum cv. Primo) responded better than temperate (Festuca arundinacea cv. Royal > Agropyron elongatum cv. Hulk), while the temperate Dactylis glomerata cv. Porto did not respond to AMF inoculation. In four of the species, the changes observed in aboveground biomass were explained by the total number of tillers, while, in P. dilatatum, changes were accounted for by the individual weight of mature tillers. On the whole, the screening of cultivated forage grasses revealed that tropical grasses were highly responsive to mycorrhizae, in contrast to a lower effect on the growth of temperate grasses.

“…In Argentina, earlier studies have found less management of AMF to increase plant productivity (Covacevich and Echeverría 2009). It is known that soils of the Pampas region present high native AMF that colonize crop plants under different management systems (Covacevich et al 2006(Covacevich et al , 2007Schalamuk et al 2006;Covacevich and Echeverría 2008); however, they are not yet manipulated.…”

“…The influence of organic matter on AMF also had contradicting results by indicating variable responses due to varying host plants and AMF species [4]. The frequency occurrence of G. species declines with increasing organic matter content while some other species like G. sinousum and G. taiwanese were found lesser than 1.5% [5].…”

Background and Objective: Arbuscular Mycorrhizal Fungi (AMF) plays a role in the structural stability of soil which governs most soil activities. Stable organic manure such as compost may provide a suitable habitat and energy source for mycorrhizal growth, which is also a benefits in view of soil productivity. The impact of a combination of compost and mycorrhizal on plant growth was assessed in this study. Hence, experiment was conducted to investigate the influence of compost and mycorrhizalon the early growth response of Parkia biglobosa under a greenhouse condition. Materials and Methods: In the greenhouse of the Department of Bioscience, Forestry Research Institute of Nigeria. A 2 × 5 factorial experiment in a complete randomized design was conducted; two levels of mycorrhizal (with and without); five levels of compost (10t/ha, 20t/ha, 30t/ha, 40t/ha and no amendments) in two (2) kilogram soil under four (4) replications was set up. Laboratory analyses of soil and organic amendment incorporated in the soil were done. Data on growth variables were taken fortnightly. The data was statistically analyzed and mean were separated using Duncan Multiple Range Test (DMRT). Results: The results showed that, there was significant difference (p<0.05) in the plant height of Parkia biglobosa between mycorrhizal and non-mycorrhizal plants across all weeks after transplanting (WAT),compost application with the interaction of AMF at 40 t/harecorded the highest plant height and number of leaves at 16WAT with 35.14 cm and 29.75 respectively, which are relatively comparable to other treatments used, the least plant height and number of leaves were observed when -AMF 0 t/ha ( control) was used as an amendment with 23.00 cm and AMF 0t/ha (15.05) respectively. For collar diameter, all the treatments were comparable to one another except + AMF 30t/ha which produced the lowest collar diameter with mean value of 2.97mm. Conclusion: Based on the description of results above, it can be concluded that: The Inoculation of the AMF and compost significantly affect the early growth performance of Parkia biglobosa, thus providing optimum soil physical conditions for it growth.
