The influence of complex organic fertilizer on the growth of biomass of poplar cuttings ‘E.s.– 38’

The Poplars (genus Populus L.) have a rapid growth and resistance to abiotic stress. They often used in urban landscaping and forest planting. The poplars reproduction by cuttings promotes of breeding achievements in forest and landscape management. The optimal conditions of lighting, temperature, moisture and soil nutrients are need for growth and development of cuttings. The purpose of this article was to study the effect of the Organic Mix fertilizer on the growth parameters of cuttings of 'E.S.–38' poplar variety. The effect of organic fertilizer "Organic Mix" on the "E.S.–38" variety poplar cuttings growth parameters detected at the first time. Study conducted for perspective poplar variety for landscaping urban areas due to its resistance to adverse environ-mental conditions. This study is aimed at evaluating the effectiveness of this organic fertilizer for accelerated cultivation of poplar seedlings of this variety, unlike other studies that used other types of fertilizers and different varieties of poplar. The height, diameter, number of leave and biomass measured in experience and control plants during the two-month research. The results of the experiment confirmed the Organic Mix fertilizer application effectiveness: the growth increase of 76% for containerized experience plants. Experimental plants dry biomass increased of twice at compared with control plants. The positive effect of Organic Mix fertilizer on the poplar cuttings growth parameters can be used for to optimize the cultivation process which contributes to an increase of high-quality planting material amount.
