“…The mean values recorded for HI in sesame showed that neither mycorrhizal inoculation nor RP fertilization had a significant effect on this parameter (Table 3). This contrasts the finding of Hagh et al (2016), who reported a positive effect of mycorrhizal inoculation on HI under low level of soil P in field grown maize. HI being a measure of crop reproduction efficiency, is influenced by a number of factors.…”

“…Mean value across treatments, LA of sesame was greater in mycorrhiza inoculated plants than in uninoculated (193.25 cm 2 and 117.24 cm 2 , Table 2) possibly due to an improved growth resulting in a total increase of photosynthetic area. Increased LA due to mycorrhizal inoculation has been corroborated elsewhere in field crops, such as sorghum (Afshar et al, 2014) and maize (Hagh et al, 2016). Mean LA indicated a general increment in treatments of no added P than fertilized with RP (192.57 cm 2 and 136.58 cm 2 ).…”

The aim of the study was to assess the effect of inoculation with arbuscular mycorrhizal fungi (AMF) and rock phosphate (RP) fertilization on biometric parameters and mycorrhizal colonization of field grown sesame under rainfed and irrigated conditions. Inoculation of AMF Funneliformis dimorphicus improved the biometric parameters of the crop such as leaf area (LA), leaf area index (LAI), specific leaf weight (SLW), net assimilation rate (NAR), oil index (OI) as well as mycorrhizal colonization (%F) in roots. Mycorrhizal inoculation however, did not give any positive response on harvest index (HI). LA, LAI and OI and %F showed a general increment in treatments of no added P (P0), while the other parameters such as SLW and NAR were improved by the application of RP at half the recommended dose (P50). HI did not respond to RP fertilization. Most of the parameters (LA, LAI, NAR, %F) showed higher values under rainfed condition than irrigated condition whereas, SLW, HI and OI improved significantly under irrigated condition. Results indicated that the inoculation of AMF to field grown sesame can compensate for 50% of the recommended P fertilizer under a need based irrigation schedule, without affecting the biometric parameters.

“…Keeping in view the above confusion that AMF respond well with P application or under deficient P conditions, Davaran-Hagh et al (2016) conducted an experiment to identify at which rate of P application AMF respond well. Among four application rates of P (25, 50, 75 and 100% recommended P) and control, G. intraradices inoculate maize plants showed higher yield and growth at 50% application rate of P. Plant P contents also increased with 50% application rate as compared to other treatments.…”

Zinc (Zn) is an essential micronutrient required to enhance crop growth and yield. In the arid – semiarid region, Zn deficiency is expected due to alkaline calcareous soil. Contrarily, Zn toxicity is also becoming an environmental concern due to increasing anthropogenic activities (metal smelting, copper industry, etc.). Therefore, balanced Zn application is necessary to save resources and achieve optimum crop growth and yield. Most scientists suggest biological approaches to overcome the problem of Zn toxicity and deficiency. These biological approaches are mostly environment-friendly and cost-effective. In these biological approaches, the use of arbuscular mycorrhizae fungi (AMF) symbiosis is becoming popular. It can provide tolerance to the host plant against Zn-induced stress. Inoculation of AMF helps in balance uptake of Zn and enhances the growth and yield of crops. On the other hand, maize ( Zea mays L.) is an important cereal crop due to its multifarious uses. As maize is an effective host for mycorrhizae symbiosis, that’s why this review was written to elaborate on the beneficial role of arbuscular mycorrhizal fungi (AMF). The review aimed to glance at the recent advances in the use of AMF to enhance nutrient uptake, especially Zn. It was also aimed to discuss the mechanism of AMF to overcome the toxic effect of Zn. We have also discussed the detailed mechanism and physiological improvement in the maize plant. In conclusion, AMF can play an imperative role in improving maize growth, yield, and balance uptake of Zn by alleviating Zn stress and mitigating its toxicity.

“…In this regard, maize is more tolerant to low P availability in soil than wheat (Postma and Lynch, 2011). This is ascribed at least in part to the stimulated root hair production (Ma et al, 2001) and mycorrhizal colonization of roots (Hagh et al, 2016) under P deficient conditions, which also enhance Zn and Cu uptake. Decreased mycorrhizal colonization with increased P rates may result in an impaired Zn uptake by maize plants (Kothari et al, 1991).…”

Decreased micronutrient concentration in cereal grains caused by excessive application of phosphorus (P) fertilizer may contribute to reduce their nutritional quality. To help correct this problem in maize grain, a 3-year field experiment was conducted to determine how P application rate affects micronutrient partitioning in maize shoots and other plant organs and micronutrient bioavailability in grain. Phosphorus application significantly decreased shoot zinc (Zn) and copper (Cu) concentrations at all growth stages but had no effects on shoot iron (Fe) and manganese (Mn) concentrations. As the P application rate increased, shoot Zn and Cu contents decreased, and shoot Fe and Mn contents increased. The ratios of pre-anthesis to post-anthesis mineral contents were not affected by P application rate except Zn. P application increased the percentage of Zn that was allocated to grain and decreased the percentage that was allocated to other tissues, but had no effects on the allocation of other micronutrients among tissues. The bioavailability of Zn, Cu, Fe, and Mn in grain decreased as P application rate increased. Overall, taking account of grain yield and nutrients concentration, P fertilizer rates should range from 12.5 to 25.0 kg P ha −1 under the local condition. It can be concluded that not only grain yields, but also nutritional quality, should be considered in assessing optimal P rates in maize.
