EVALUATION OF QUALITATIVE FEATURES OF MIKON CULTIVAR WINTER WHEAT GRAIN AND FLOUR DEPENDING ON SELECTED AGRONOMIC FACTORS
Tomasz Knapowski, Maria Ralcewicz
ABSTRACT
A field experiment was carried out at the Minikowo Agricultural Experiment Station the vicinity of Bydgoszcz and aimed at defining the effect of the sowing date and nitrogen fertilisation on yielding and selected technological parameters of ‘Mikon’ winter wheat grain and flour. Two sowing dates were applied (factor I): optimal in a given year and 2-week delayed date and 4 nitrogen fertilisation levels (factor II): 0, 80, 120 and 160 kg N·ha-1. The sowing date delayed by two weeks, as compared with the optimal date, significantly decreased the grain yield by 6.6% and increased the content of wet gluten and the value of sedimentation ratio. The dose of 120 kg N·ha-1 was most favourable for ‘Mikon’ winter wheat yielding. A further increase in N fertilisation used to show a tendency for decreased wheat yielding. The qualitative indicators researched showed a growing tendency throughout the range of the nitrogen doses applied. However the nitrogen fertilisation le
