SYMBIOTIC EFFICIENCY OF BACTERIAL AND FUNGAL PREPARATIONS FOR FORAGE CROPS ACCORDING TO SEED HARVEST

The article presents the results of long-term experiments conducted in the framework of geographical experiment net of the All-Russian Research Institute for Agricultural Microbiology. We estimated the symbiotic efficiency on forage crops for biopreparations based on root nodule bacteria (‘Rhizotorfin’), and on fungus of arbuscular mycorrhiza (AM) — Rhizophagus irregularis. Applying ‘Rhizotorfin’ provided seed gain for all variants with legume crops. AM fungal inoculum being effective for forage crops from different families because of lack of specificity in interactions with plants.

Obtained data were consistent with the hypothesis about key role of AM in phosphate plant nutrition. The developed mycorrhizal biopreparation prototype will have high efficiency under condition of lower level of phosphorus available for plants. According to study results, authors recommend ‘Rhizotorfin’ primarily for alfalfa (Medicago varia), fodder galega (Galega orientalis), and soybean (Glycine hispida) and AM inoculum application-primarily for barley (Hordeum vulgare), winter rye (Secale cereale), red fescue (Festuca rubra), and spring wheat (Triticum aestivum).
