abstract:
In the period 2006-2008, a study was conducted on the effect of tillage systems and catch crops on the physical properties of spring wheat grain determined using the SKCS instrument. At the same time, the content of ash, fibre and fat in the grain was estimated. In the plough tillage treatments, kernel weight and equivalent diameter estimated using the Single Kernel Characterization System (SKCS) were significantly higher than in the conservation tillage treatments. The hardness index was higher in the conservation tillage treatments compared to plough tillage. The highest moisture, ash and fibre content in the spring wheat grain were found in the conservation tillage treatments with spring disking of the catch crops. On the other hand, the highest grain fat content was found in the conservation tillage treatments without mulch. Kernel weight and equivalent diameter were significantly lower in the treatment with Westerwolds ryegrass than in the treatments with the stubble crops of lacy phacelia and white mustard. Whereas, the grain moisture content was higher in the plots with Westerwolds ryegrass relative to the other catch-cropped treatments. The highest ash content was found in the control treatment and in that with Westerwolds ryegrass. The highest fibre content in the grain was found in the treatments with white mustard, the lowest one in those with red clover. The fat content in the grain from the treatments with lacy phacelia and white mustard was the highest, whereas in the plots with red clover it was the lowest.
