Продуктивность сильфии пронзеннолистной в зависимости от способа размножения
2018
The article presents 6 years study of productivity structure and productivity of green mass of Silphium perfoliatum L. grown both by seed and by root stem of different density methods. It was found that density of plants affects stem-forming ability. Herbage of a highestplant density has the biggest and the highest leaves of the first mowing. Due to intensively sowing the plants were higher by 3.8 sm. Analysis of date shows that variant of root stem sowing with location scheme of 70 thousandplant units per hectare allows us to obtain productivity by experimental variants of 112.4-112.8 t/ha if hydrationis optimal during the year
