Effect of sterilized and unsterilized stable manure and compost on the efficiency of VA mycorrhiza Under greenhouse conditions, it was examined how the three organic manures stable manure, compost out of stable manure and compost out of plant rests in comparison with the corresponding amounts in sterile and homogeneous form, influence the efficiency of VA mycorrhiza cultivated with Capsicum annuum. The manures had been added in 4 stages of concentration: 50, 100, 200 and 300 dt/ha. In the unsterile treatment the generally positive efficiency of VA mycorrhiza on plant yield decreased with increased amounts of the organic manures. How fast this reduction took place, was dependent on the different kinds of manures. The effect of the inoculation were much better in the unsterile treatment, compared with the sterile one, when the offer of the possible nutrient sources by the manures were low and the relation of the nutrients in the soil solution were unfavorable. The activity of the soil microorganisms always have played a decisive role for this results.
