Journal Title: Лісівництво і агролісомеліорація - Year 2016, Vol 129, Issue
Abstract
The article deals with the results of study of amino-acid humate fertilizer “Rokohumin” using for growing containerized planting stock of oak in individual containers made of an agrotextile. It was established that the effectiveness of the fertilizer depends on the input method and concentration of working solutions. The maximum effect on strengthening of growth in height and diameter of root collar and increase air-dry weight of aboveground and underground parts of seedlings was obtained in a variant with fertilizer solution concentration of 20 ml•l-1. The average height of seedlings in this version is bigger by 81 %, diameter by 42 %, mass of aboveground and underground parts by 68 % and 27 % respectively. Leaf feeding with fertilizer solution 10 ml•l-1 contributed to more active growth in height by 45 % and increase the weight of aboveground parts by 25 %. Leaf feeding did not affect on root weight. The use of "Rokohumin" gives an opportunity to obtain planting material with given sizes, including large-sized, for use not only in silvicultural work, but in horticulture.
