| Title : | EFFECTS OF COMBINED TREATMENT OF SEEDS OF TWO PEA VARIETIES WITH BACTERIAL INOCULANTS |
| Abstract : | The series of the field experiments on pea inoculation with three kinds of bacteria were conducted in Dnipropetrovsk province situated in the northern part of steppe zone of Ukraine. The main objective of our research was to study effects of combined seed treatment of two pea cultivars with bacterial inoculants. The largest leaf surface area of pea cultivars was formed in the stage of flowering in the combine inoculation with bacterial strains Rhizobium leguminosarum, Bacillus megaterium and Paenibacillus polymyxa (PP). The three-component mixture provided nitrogen fixation with rhizobium (R) and phosphorus soluble mobilization (PSB) and has led to a significant increase both the total number of nodules (by 1.4-2.0 times) and their active forms (by 1.3-2.0 times) on the pea root system. The treatment of seeds of two pea varieties with bacterial inoculants made it possible to increase the yield of pea grain up to 13%. The effect of pea seeds bacterial inoculation against the N20P40 background was less effective. The highest effect was recorded after inoculation of pea seeds with Rhizobium leguminosarum. The use of a double (PSB + PP) and triple mixture (PSB + PP + R) of bacterial inoculants provided the second place to an increase in the nitrogen content in the foliar mass of plants in both treatments (without and with mineral fertilizers). The amounts of phosphorus and potassium uptake in the foliar mass were higher in the PSB version (without fertilizers), and in the treatment with the use of P.Polymyxa - with the use of N20P40 fertilizers. |
