  Impact of Arbuscular Mycorrhizal Fungi and Fertilization Levels on biochemical changes in potato (Solanum tuberosum L., Solanales Solanaceae)

  ABSTRACT
  Experiments have been carried out to evaluate the potential biochemical mycorrhizal benefit of potato (Solanum tuberosum L., Solanales Solanaceae) grown in northeastern Algeria. Three doses of chemical fertilizer (NPK) corresponding to 0, 50 and 100% of the recommended dose have been applied in presence or not in presence of the mycorrhizal inoculant. The results have revealed that the additional contribution of arbuscular mycorrhizal fungi combined with 50% chemical fertilizer gives the best results. A significant increase has been observed at the root colonization and chlorophyll content level. In terms of tuber quality, there is a significant increase in starch and protein content. However, the application of mycorrhizae alone will not compete with synthetic fertilizers in vegetable gardening, but could reduce their applications and thus improve yield while preserving the environment.
