EFFICIENCY OF RHIZOHUMIN AND POLYMYXOBACTERIN APPLICATION IN COMBINATION WITH MICROFERTILIZER AND GROWTH REGULATOR ON LEAFLESS PEA CROPS IN NORTH STEPPE

The paper presents trial results on application of microbial preparations of Ryzohumin and Polymyxobacterin in combination with plant growth regulator Emistim C and microfertilizer Reakom on leafless peas crops in Northern Steppe region. Use of biological preparations have promoted increase of pea plants on 0.27 – 0.38 t / ha or 12.8 – 18.1%, microfertilizer Reakom – on 0.36 t / ha or 15.5%, Emistim C – on 0.39 – 0.41 t / ha or 16.8 – 17.7%, and at their combined use – on 0.22 – 0.55 t / ha or 9.5 – 23.7%.
