ABSTRACT
The studies on the effect of extract of spruce and pine cones on growth and development of cucumber plants grown seedlings were carried out by us in the pot experiment in phytotron of Pryanishnikov All-Russian Scientific Research Institute of Agrochemistry. We tested variants watering cucumber plants with extract from the crushed cones of spruce and pine trees and with water such as (1) control with water irrigation; (2) watering 0.2% extract from crushed cones; (3) applying chicken manure at the rate of 100 kg/ha of nitrogen in combination with water irrigation; (4) applying chicken manure at the rate of 100 kg/ha of nitrogen in combination with irrigation of 0.2% extract of crushed cones. Based on the studies, we found that when growing cucumber seedlings the most efficient was the use of chicken manure in combination with coniferous cones extract irrigation, in which-an increase of aboveground biomass in relation to watering with tap water was 81.6% and increase of the root biomass-97.1%.
