APPLICATION OF A LOW-FREQUENCY ELECTROMAGNETIC FIELD FOR PRESOWING TREATMENT OF PEA SEEDS

It was established that the laboratory and field germination of the treated pea seeds of the Nord and Truzhenik varieties by a low-frequency electromagnetic field was higher compared to the control by 2…4%, the length of roots and sprouts of seedlings by 9.3-33.8%. There were no significant varietal differences in the length of seedlings in treated pea seeds. The most optimal time for processing pea seeds with an electromagnetic field is 2 hours. The average increase in the yield of Nord peas during seed treatment with an electromagnetic field (EMF) for 2 and 3 hours was 0.11–0.12 t/ha, or 18.3-20.6%, for peas of the Truzhenik variety – 0.12 t/ha (16.2%). The positive effect of the combined use of the electromagnetic field and the preparation Darina on the seeds of the Orlus pea has been established. An increase in germination energy, laboratory and field germination of treated seeds to control by 4-6%, an increase in the length of seedlings – by 16.0-24.3% and productivity – by 0.29 t/ha (12.9%) were noted. The combined use of the EMF device "Biomag" and preparations of Potassium Humate, Ribav-Extra also had a positive effect on the sowing qualities of pea seeds varieties Orlus and Truzhenik. The length of pea seedlings exceeded control seedlings by 16.2-18.0%. Germination energy and laboratory germination exceeded these control indicators by 3-4%. Field germination of the treated pea seeds of the Orlus variety by the low-frequency electromagnetic field of the Biomag device and Potassium Humate exceeded the control by 6%. The yield increase was 0.17 t/ha (7.4%). The combined use of the electromagnetic field and the preparation Ribav-Extra increases the field germination of seeds to the control by 8%, the yield of peas - by 0.31 t/ha or 13.4%. The treated seeds of Orlus peas by the electromagnetic field "Biomag" with the subsequent encrustation of the treated seeds with the preparations Potassium Humate, Ribav-Extra increase the number of beans and seeds from one plant by 11.4-15.1% to the control. The weight of seeds per plant was higher than the control by 0.3-0.6 g or 8.9-18.5%, and the weight of 1000 seeds – by 1.8- 2.7%.
