The effect of mycorrhizal inoculation on nitrogen fixing and non-fixing, plant growth and macro- and micro-nutrient uptake was observed under field conditions. Several field experiments were set up on Çukurova University research farm (Eastern Mediterranean region). In one experiment clover, lentil, onion, garlic, chickpea and horse-bean plants were used. Cocktail mycorrhiza was used. The results showed, that in mycorrhizal plots, plant yields were higher than in non-mycorrhizal plants. Mycorrhizal inoculation also increased Cu and Zn content in the shoot. In another experiment, carried out under field conditions for three successive years on horse-bean, chickpea and soybean plants, mycorrhizal inoculation was successively applied in sterile and non-sterile soil conditions with and without phosphorous application. Mycorrhizal inoculation significantly increased horse-bean, chickpea and soybean yields. Garlic, chickpea and horse-bean did not grow very well in fumigated plots compared to the non-fumigated ones. In fumigated plots, mycorrhizal inoculation significantly increased growth and nutrient uptake of horse-bean and garlic. Inoculation of the soil with mycorrhizae strains significantly increased plant growth and P uptake of plants, especially under low P supply. In low P application, plant roots were strongly infected and consequently increased plant growth, but with high P level there was a slight reduction in root infection. The results show that mycorrhizal inoculation is an effective practice for improving crop production in P-deficient soils.
