The optimization of the fermentation process of wort from apples Spartan varirty for the unfortified sweet wines

Abstract

On average, over three years, the metabolic energy content in the grain yield of spring triticale of the Solovei Kharkiv variety was 48.2 GJ/ha in the case of no fertilizer and increased to 58.5-74.6 GJ/ha in the background + N 30-150 versions. For the retail application of nitrogen fertilizers, the indicators came short of the single nitrogen application, especially in the background + N 0 + N 30 (52.6 GJ/ha) version, and the background + N 60 + N 60 + N 30 (67.3 GJ/ha) version came short least of all. The nitrogen application contributed to the increase in the feed units' collection per planting acreage unit. On average, over the three years of research with no fertilizer, it was 8.08 t/ha and increased to 9.8-12.5 t/ha, with the single application of N 30-150 , while the retail nitrogen application markedly decreased and amounted to 8.82-11.29 t/ha.
