Efficiency of Pre-Sowing Treatment of Common Spruce Seeds With Such Fertilizers as “Bioplant Flora”, “Gumat” and Nitrogen Fertilization

Abstract

The article presents the results of 4-year field studies to identify the efficiency of pre-sowing treatment of common spruce seeds with drugs “Gumat” and “Bioplant Flora”, as well as the introduction of various nitrogen fertilizers for growing seedlings. The studies were conducted in 2008-2011 on sandy loam, sod-podzolic soil of basic forest nursery “Training and experimental suburban forestry”, which is located in the Kama climatic zone of the Republic of Tatarstan. Studies have found that pre-sowing seed soaking by drugs increases the productivity of standard seedlings, an application of nitrogen fertilizer has a positive effect on biometrics (diameter of trunks at the root collar, height and etc.) of common spruce seedlings.
