RESEARCHES REGARDING THE YIELD AND QUALITY OF SOME WINTER WHEAT VARIETIES IN INTERACTIONS WITH NITROGEN FERTILIZATION PUBLISHEDGheorghe Bunta, ELENA BUCUREAN
In this paper are presented some results regarding the yielding potential of a new own wheat variety, Crisana comparative to another Romanian wheat varieties in last three years, 2008, 2009 (very drought) and 2010 (very raining) in western part of country. Also, we present some results regarding the backing qualities of this new variety comparative to another ones, in last years. The results confirm that our new variety, Crisana, registered in 2005, is one of the best wheat varieties, regarding the yielding potential and backing qualities, with or without nitrogen fertilization. This paper presents the qualities indicators and yields potentials of the cultivars in two comparative variants, fertilized and unfertilized with nitrogen. The results demonstrate that it is possible to create wheat varieties that have in the same time, good yielding potential and very good qualities, like wet gluten, protein, falling number, Zeleny index, etc. The results demonstrate that Crisana has a good yielding potential in the years with very drought spring and summer (like 2009) but not so good in excessive raining year. In the same time, its quality indicators are stable from a year to another and it is competitive to another Romanian and foreign cultivars.
