INFLUENCE OF PRESOWING IRRADIATION OF SEEDS BY MICROWAVE HIGH FREQUENCY FIELD AND PLANT GROWTH REGULATOR FOR FORMATION OF DENSITY OF PLANTS AND YIELD OF WINTER WHEAT
Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 4, Issue 4
Abstract
The research on the effect of environmentally sound technology of pre-sowing microwave radiation of seeds and application of plant growth regulator on winter wheat in the Eastern part of the forest-steppe of Ukraine is presented. Processing of seeds of MWF in ultrahigh-frequency in modes of 1,8 kW/kg, 15 sec. and 0,9 kW/kg, 45 sec, separately and in combination with the plant growth regulator, Mars EL caused an to the increase of field germination of seeds winter wheat, respectively, to 6,7-7,2 % and 5,3-8,0 %, compared with control – 90,2 %, plant density during autumn tillering by 4,5 and 6,7% and by 9,5 and 6,5 %, respectively, at 398 pc/m2 on the control, as well as density plants in the phase into the tube by 12,3 and 13,9 % and 15,0 and 9,9 %, respectively, which resulted in the formation of a greater number of productive stems in variants with seed treatment of MHP in ultrahigh-frequency and plant growth regulator at 39-56 pc/m2 or 7,9-11,3 %, at the 496 pcs/m2 on the control, and as a result of the increase in winter wheat grain yield by 0,24 t/ha (or 4,5 %) for pre-seed treatment of MWF in ultrahigh-frequency in the mode: 1,8 kW/kg seeds and exposure 15 sec with additional processing by plant growth regulator Mars EL or MWF in ultrahigh-frequency in the mode of 0,9 kW/kg of seeds and exposure for 45 seconds.
