Evaluation of quality and quantity parameters in winter wheat production on chernozem soil

Abstract

The winter wheat is one of mankind's ancient grains and in Hungary's plant cultivation is one of the most important crops (Barnard Bona, 2004). Winter wheat is produced almost on every farm or estate. It is vital to focus on the quality of the crop not only on its quantity. The quality of winter wheat is determined by the biological basis, the agro-ecological circumstances and the agro-technology altogether (Bocz et al., 1983, Pep6, 2000). In the last decade the level of agronomical expenditures decreased. Plant improvement tried to adjust itself to the reduced input application and resulted in the appearance of more and more, stronger varieties with better adaptability (Pep6, 2002). Hungary's agro-ecological characteristics provide adequate ground for the qualitative wheat production (Szabb et al., 1987). From the agro-technical factors, the nutrient supply has a significant effect on the quality and quantity of wheat (Ragasits, 1998). A fertilizer in the adequate dose, rate and division can ensure the quality parameters and moderate the negative effects of the unfavorable ecological and agro-technical factors (GySri et al., 1998, Jol&nkai et al., 1998).
