Regarding effects of water stress on plant, many research reports have been release during recent years, but, studies on effects of this stress on biochemical parameters and mineral content at an early stage are scarce. This study investigated drought stress effects on some biochemical parameters and mineral content of mycorrhizal Vigna subterranea plant, in a randomized block design. The microbial material comprised of a mixture of locally selected arbuscular fungi. The four levels of watering expressed in % of field capacity were: 90, 60, 30 and 15; with or without mycorrhizal inoculation. Experiment was carried out on a sterilize substrate during 31days of water stress. Results showed that with increasing level of water stress, mycorhization increased: mineral content, both soluble sugars and acid phosphatase, but lessened proline content. Arbuscular mycorrhizal fungi (AMF) could thus be an effective tool in the alleviation of harmful effects of drought stress on plants, by improving their tolerance to this abiotic stress and consequently contributing to a better growth of V.subterranea.
