INFLUENCE OF URBAN SEWAGE SLUDGE ON THE SPRING PRODUCT OF SPRING TRITICALE

Abstract

Fertilizer plays an active role, providing one or another degree of plant variability. It is an element of natural selection in an indirect form, since it provides the advantage of genotypes that are specifically adapted to competitive environmental conditions. The article presents the results of a study of the effect of the use of urban sewage sludge (USS) as fertilizer for the yield of spring triticale of the Ukro variety on dark gray forest soil. The studies were carried out in 2014-2016 at the site of FSBEIHE Penza SAU. It was established that the use of urban sewage sludge contributed to an increase in the yield of spring triticale of the Ukro variety. The maximum yield of 3.79 t/ha was obtained in the option with USS at a dose of 10 t/ha and a sowing rate of 4.0 mln. grains per 1 ha. The increase in relation to control was 0.27 t/ha.
