Probability breeding of tall fescue (Festuca arrundinaceae Schreb.) in reclamation of deposol of Stanari
Abstract
In the paper we showed result of reclamation and foundation of tall fescue (Festuca arrundinaceae Schreb.) graslands on deposol of Stanari. Research have been performed on technogenious soil of exterior deposit overburden of surface mine Raškovac - Stanari, for a biennial period (2009/2010). Seven different treatments of fertilizing of crops with nitrogen have been applied according to incidental block system. Analysis of soil conditions showed sandy deposol with a very low fertility. The greatest average yield of green mass (31,6 t ha'1) and dry matter (12,76 t ha'1) in both years have been accomplished with with application of the highest dose of nitrogen (160 kg ha'1 ha N). Appliance of treatment with 60 kg ha'1 N showed the least fluctuation of yield. The best effect of fertilization with nitrogen on hay yield have been achieved with the lowest dose of fertilization (40 kg ha'1 N). Absence of application of nitrogen fertilizers in fertilization of tall fescue grasslands founded at reclamation deposol of mine lignite Stanari inevitably leads to termination of growth and development of plant mass on it.
