“…Little root colonization rate (20-40%) was also observed in non-inoculated plants because Thiophenate was not properly inhibit root colonization only reduced its growth [42]. Irrespective of AMF inoculation high Zn supply negatively affect the plant growth parameters and yield as reported in previous studies [16,37].…”

Zinc (Zn) concentration in soil varies from deficient to toxic. Its deficiency, as well as toxicity through imbalance application, can reduce maize growth and yield. Therefore, balanced application of Zn is a necessity of time to save resources and to achieve optimum growth and yield in maize. Arbuscular mycorrhiza fungi (AMF) can provide tolerance to host plant against Zn induced stress. Inoculation of AMF not only helps in balance uptake of Zn but also enhance growth and yield of crops. That’s why in the current efficacious function of AMF, i.e., Glomus specie was assed. Different application rates of Zn (0, 20, 40, 60, 80, 100 and 120 mg Zn/kg) were applied with AMF (AM) and without AMF (NM). Results showed that root colonization level was 45% higher in AMF inoculated plants as compared with non-inoculated plants. A significant increase in plant height (15%), number of leaves (35.4%), cob weight (4.39%), 1000 grains weight (10.5%) and biological yield (42.2%) signified the efficacious functioning of Zn20+AM over sole inoculation of AM. We also observed that AMF inoculation with Zn20 helped in improved photosynthesis, transpiration and stomatal conductance. Furthermore, both Zn20+AM and Zn20+AM were significantly better for the improvement in total soluble protein over AM in maize. Higher application rates of zinc, i.e., Zn80 and Zn120 induced Zn toxicity with (AM) and without (NM) AMF. In conclusion, Zn20+AM is an effective amendment to achieve better growth and yield of maize without Zn deficiency or toxicity.

“…The most beneficial effects were observed with A. brasilense and P. fluorescens co-inoculation in the rice rhizosphere. Inoculation of microorganisms is influenced by agricultural practices ( Velusamy, Immanuel & Gnanamanickam, 2013 ) improving both growth and nutrient acquisition ( Khan, 2018 ) of rice grown under upland conditions ( Rajeshkannan, Sumathi & Manian, 2009 ; Zhang et al, 2017 ).…”

Organic and biological fertilizers are considered as a very important source of plant nutrients. A field experiment was conducted during 2017−2018 in paddy soil to investigate the effect of vermicomposting of cattle manure mixture with Azolla and rice straw on soil microbial activity, nutrient uptake, and grain yield under inoculation of N2-fixing bacteria. Experimental factors consisted of organic amendments at six levels (vermicomposts prepared from manure (VM); manure + rice straw (VRM); manure + Azolla mixture (VAM); manure + rice straw + Azolla mixture (VRAM); raw manure without vermicomposting (M), and a control) and N2-fixing bacteria at three levels (Azotobacter chroococcum, Azospirillum brasilence, and non−inoculation). The results showed that, vermicompost treatments compared to control and raw manure significantly increased the number and biomass−C of soil microorganisms, urease activity, number of tillers hill−1, phosphorus (P) and potassium (K) uptake, and grain and protein yield. Inoculation of plants with N2-fixing bacteria, especially Azotobacter increased the efficiency of organic amendments, so that the maximum urease activity, soil microbial activity, P and N uptake, and grain yield (4,667 (2017) and 5,081 (2018) kg/h) were observed in vermicompost treatments containing Azolla (VAM and VRAM) under inoculation with Azotobacter. The results of the study suggested that, using an organic source along with inoculation with appropriate N2-fixing bacteria for vermicompost has a great effect on enzyme activity, soil biology, nutrient uptake and grain yield has a synergistic interaction on agronomic traits under flooded conditions. Therefore, this nutrient method can be used as one of the nutrient management strategies in the sustainable rice production.

“…AMF response to soil fertilization is dependent on the soil nutrient gradient and host nutrient status (Treseder and Allen, 2002). Several studies had been conducted in the past on the effect of different combinations, especially NPK on AMF colonization (Hepper, 1983;Rajeshkannan et al, 2009;Treseder and Allen, 2002). One common trend was that increased P fertiliser depresses AMF root colonisation (Jensen and Jakobsen, 1980).…”

A screen house trial was conducted to evaluate reproductive growth responses of drought tolerant upland rice cultivars (NERICAs 1-4, WAB 56-104 and Moroberekan) to arbuscular mycorrhizal (AMF) inoculation under water deficit. A field trial was organized in randomized complete block test with three replicates, conducted in the late cropping season of 2012. We evaluated upland rice cultivars to different nutrient sources (AMF, AMF + 60 kg N ha -1 + 30 kg K ha -1 , 60 kg N ha -1 + 30 kg K ha -1 and control). In the screen house inoculated rice had higher (P < 0.05) grain yield plant -1 (19.29 g plant -1 ) and its attributes than non-inoculated, except number of grain per panicle (108). On the field combination of AMF + 60 kg N ha -1 + 30 kg K ha -1 produced higher (P < 0.05) reproductive growth. Varietal variability (P < 0.05) was observed on AM colonisation and reproductive growth in both trials, with 'NERICA 2'was the most promising cultivar under tested agroecology condition.
