To establish the biological characteristics of growth and development of plants and the formation of
planting material of miscanthus under conditions of drip irrigation. Methods. Field, laboratory, visual, measuring,
weight, mathematical-statistical. Results. Represented the effectiveness of cultivation of planting material of
miscanthus under conditions of drip irrigation without the application of Maxi Marin absorbent and when it is added
to the period of planting of the rhizome. High survival of miscanthus plants in transplanting them from growing to
open ground is established. In the conditions of drip irrigation it was 4.9% (without absorbent) and 3.3% (for making
absorbent) more than without irrigation was. Drip irrigation significantly influenced the plant height and the
formation of stems, while the introduction of absorbent was observed only a tendency of increase of these indicators.
Introducing absorbent in rainfed conditions has resulted in a substantial increase in the content of free water in the
leaves of miscanthus. Drip irrigation has contributed to intensive growth of not only land mass, and the mass of roots
that provided a significant increase in the yield of planting material - the rhizome. The average for years of research
weight uterine rhizome in drip irrigation was greater in control (without absorbent) by 62.8%, or 917,9 g than the
absorbent application, respectively, the 61.8% or 912,7 g compared to irrigated conditions. Conclusions. The use of
an absorbent as in rainfed conditions without irrigation, and in drip irrigation did not provide the increase of
biometric parameters of the plants, weight of roots and, consequently, the output of planting material - the rhizome.
The increase of these indicators was significantly affected only drip irrigation. In drip irrigation without any
absorbent and when it is added from one of the ovaries rhizomes obtained mass was 15-20 g in 1.5 and weighing
25-30 g in 1.4 times more compared to the cultivation of ovaries without irrigation.
