Abstract
Grain samples of wheat obtained from a field experiment conducted in 1999 in Experimental Station Osiny constitute the material for quality analyses. The investigated factors were following: 3 cultivars of winter wheat (Kobra, Mikon, Sakwa) and methods of plant protection (control, conventional, integrated, integrated with the stimulator Bion. Application of the 3 plant protection methods, in comparison to the control, caused high increase of grain yield and 1000-grain weight, and simultaneous decrease of grain protein content and other quality parameters. Different plant protection methods did not cause significant differentiation of quality traits of wheat grain. The only changes were observed in 1000-grain weight and test weight. Reaction of the cultivars to the investigated plant protection methods was similar. No remarkable differences in grain quality between cultivars were observed.
