Mycorrhiza fungi can use as an efficient resource to increase the efficiency of potato nutrients use, especially phosphorus (P) and nitrogen (N) to achieve sustainable production and protecting the environment and human health. This experiment conducted to study the interaction of P levels and mycorrhiza fungi on absorption of elements and qualitative and quantitative yields of potato under field conditions. Factors including inoculation of mycorrhiza fungi (Rhizophagus irregularis and Glomus mosseae and non-inoculation) and the amount of P (0, 28, 57, 86 and 115 Kg ha⁻¹ P according to H₂PO⁻⁴, equivalent 0, 25, 50, 75 and 100 percent of P recommended, respectively), with three replications in years 2015 and 2016 at Agriculture and Natural Resource Research Center of Hamadan. The results showed that the maximum of P in tubers (0.351%) and leaves (0.364%), Zn in tuber (24.4 ppm) and leaves (43.9 ppm) and tuber dry matter percentage (24.1%) achieved under inoculation with Rhizophagus irregularis and using of 75% of recommended Phosphorus. Maximum tubers number per plant (7.2) obtained in inoculation with G. mosseae and using of 100% recommended P. Highest tubers weight per plant (898 g) and tuber yield (47.9 ton ha⁻¹) were achieved under inoculation with G. mosseae and using of 75% of recommended P. Both species of mycorrhiza at all levels of P did not show significant difference. The P 75% and 100% under mycorrhizal inoculation treatment did not show significant difference. Highest nitrate percentage in tuber dry matter (136 ppm) and lowest amount of all traits were under non-inoculation along with no application of P. Inoculation treatment with mycorrhizal fungi significantly increased the average weight of tuber compared to non-inoculated treatment. Generally, the use of mycorrhizal fungi at low levels of P was more efficient on all studied traits compared to high levels of P. Given that, there was no significant difference between 75% and 100% P under inoculation with two species of mycorrhiza, provided this conclusion that applying mycorrhizal fungi can reduce agricultural phosphorus consumption without significant decrease in yield.

菌根真菌可以用作提高马铃薯养分利用效率的有效资源，尤其是磷（P）和氮（N）的使用，以实现可持续生产并保护环境和人类健康。该实验旨在研究田间条件下磷水平和菌根真菌对马铃薯元素吸收及定性和定量产量的相互作用。因素，包括的菌根真菌（接种Rhizophagus irregularis和球囊霉和非接种）和P（0，28的量，57，86和115公斤公顷^-1按H P ₂ PO ^-4，分别推荐相当于P的0％，25％，50％，75％和100％），并于2015年和2016年在哈马丹的农业和自然资源研究中心进行了3次重复试验。结果表明，接种不规则根瘤菌和根瘤菌后，块茎和叶片中的磷最大（0.351％），叶中最大（0.364％），块茎和叶片中的锌（24.4 ppm）（43.9 ppm）和块茎干物质百分比（24.1％）最大。建议使用75％的磷。与接种获得的单株最大块茎数（7.2）G.霉和使用100％推荐每株植物（755克）和块茎产量（47.9吨公顷P.最高块茎重量^-1）与下接种分别实现G.霉以及使用推荐的P的75％。在P的所有水平上，两种菌根均未显示出显着差异。菌根接种后的P 75％和100％没有显着差异。在不接种和不施磷的情况下，块茎干物质中最高的硝酸盐百分比（136 ppm）和所有性状的最低值。未接种菌根真菌的接种处理显着增加了块茎的平均重量。一般而言，低磷水平的菌根真菌在所有研究的性状上均比高磷水平更有效。鉴于接种两种菌根，接种75％和100％磷之间无显着差异，
