Abstract:
Mycorrhiza can be used as an efficient tool to increase nutrients productivity to achieve sustainable agriculture. This experiment conducted to investigate the interaction of phosphorus and mycorrhiza on growth characteristics and production of mini-tuber and nutrients uptake of seedlings under greenhouse condition. The experiment was arranged as factorial in completely randomized design with three replications in agricultural and natural resource research center of Hamadan in 2015. First factor included of inoculation with mycorrhizal fungi, Rhizophagus irregularis, (inoculated and non-inoculated) and the second factor was the amount of phosphorus (0.965, 0.482, 0.241 and 0.12 mM phosphorus according to H2PO-4 in Hoagland solution (100, 75, 50 and 25 percent of Hoagland complete phosphorus concentration (HCPC), respectively). The results showed that the maximum values of seedling establishment (98.3%), number of leaves (13.3), the number of mini-tubers (8.9), the total weight of mini-tubers per plant (53.2 g), shoot height (54.6 cm), phosphorus in mini-tubers dry matter (%0.38) and leaves (%0.363) observed in phosphorus 75% HCPC and inoculation treatment and no significant differences was seen relative to phosphorus 100% HCPC and inoculation treatment. Inoculation with mycorrhizal fungi significantly increased the mini-tubers and leaves nitrogen, dry matter and weight of mini-tuber relative to non-inoculated treatments. Generally, respect to that there was no significant difference between 75% and 100% phosphorus in inoculation treatment, the applying of mycorrhizal fungi can reduce agricultural inputs consumption without any significant decrease in yield.
