“…Thus, low levels of phosphorus can affect symbiosis by decreasing the supply of photosynthates to the nodule, which reduces the rate of bacterial growth and the total population of legume-nodulating microorganisms (Moreira et al, 2010). This also suggests to us that the efficiency of nitrogen fixation by the strains approved as inoculants may be related to a greater ability to solubilise low soluble phosphates; however, no studies have experimentally demonstrated this so far.…”

Microbial solubilisation of low soluble inorganic phosphates is an important process contributing for the phosphorus available to plants in tropical soils. This study evaluates the ability of inoculant strains for tropical legumes to solubilise inorganic phosphates of low solubility that are found in tropical soils. Seven strains of Leguminosae nodulating bacteria (LNB) were compared with one another and with a non-nodulating positive control, Burkholderia cepacia (LMG 1222 T 3 . In liquid GELP medium, LMG 1222 solubilised all phosphate sources, but no legume nodulating strain could increase the solubility of Al(H 2 PO 4 ) 3 . The strains CIAT 899 and UFLA 02-100 were the only legume nodulating bacteria able to solubilise the other phosphate sources in liquid media, dissolving both CaHPO 4 and FePO 4 .2H 2 O. There was a negative correlation between the pH of the culture medium and the concentration of soluble phosphate when the phosphorus source was CaHPO 4 or FePO 4 .2H 2 O. The contribution of these strains to increasing the phosphorus nutrition of legumes and non-legume plant species should be investigated further by in vivo experiments.

“…These results indicate that a better relationship was established using SSP fertilizer rate in improving the post-harvest soil total nitrogen concentration, fresh pod weight per plant and number of nodules per plant. Various workers [32,39,40] noted that phosphorous deficiency has been shown to affect symbiosis by decreasing the supply of photosynthates to the nodule, which reduces the rate of bacterial growth and the total population of legume-nodulating microorganisms [41][42][43][44][45][46]. Reported that enhancement in nodule number, nodular mass due to inoculation might lead to the expansion in root length and mass, thus more number of active sites for nodulation by the rhizobial strains.…”

“…In 2010/11, when 120 kg ha -1 P 2 O 5 was added to the soil, formononetin did not affect mycorrhizal colonization. In fact, the addition of high levels of P tends to inhibit or limit mycorrhizal colonization, and in conditions of low P availability, mycorrhization tends to be higher compared with plants receiving the maximum supply of P (MOREIRA et al, 2010).…”

“…Synergetic effects of this tripartite symbiosis have been observed, mainly in conditions of low levels of P and N (MOREIRA et al, 2010;WANG et al, 2011). Despite the known beneficial effects of these fungi, their use in agriculture is limited because they are obligate biotrophs and their inoculum mass production is economically unviable.…”

Arbuscular mycorrhizal fungi play an important role on nutrient supply to plants, specially P.However, the availability of inoculants for large-scale usage in agriculture is still limited because these organisms are obligatory symbionts. The use of symbiosis stimulants such as flavonoids can be an alternative to improve the beneficial effects of mycorrhiza for plant nutrition. The aim of this study was to evaluate the effect of the isoflavonoid biostimulant formononetin (7-hydroxy, 4'-methoxy isoflavone) in combination with three levels of phosphorus fertilization on mycorrhizal colonization, nodulation, and productivity of soybean, under field conditions. A 3 x 4 factorial scheme (levels of P: 0, 60 and 120 kg ha -1 P 2 O 5 and doses of formononetin: 0, 25, 50 and 100 g ha -1 ) was used with five replicates. The following parameters were quantified at full bloom: plant height, shoot dry weight, nodule number, nodule dry weight, mycorrhizal colonization, and shoot N and P concentrations. Productivity was also evaluated at the end of the crop cycle. Formononetin stimulated mycorrhizal colonization at lower levels of P (0 and 60 kg ha -1 ), with colonization increasing from 56 to 64%. When applied with 60 kg ha -1 P 2 O 5 , formononetin increased soybean productivity to values similar to those observed when 120 kg ha -1 de P 2 O 5 , was applied. At doses above 50 g ha -1 , formononetin applied to the seeds can reduce the need of P fertilization by 50%.
