Yield and chemical composition of spring triticale grain depending on cropping and tillage systems

A field experiment was conducted to evaluate the yield and chemical composition of triticale grain in different crop rotation and tillage systems. The first experimental factor was the cropping system – a) crop rotation and b) monoculture and the second factor was the tillage system – 1) conventional (CT), 2) reduced (RT) and 3) no-tillage (NT). The spring triticale yield was found to be 15.4% higher for crop rotation than for monoculture and 19.4-22.4% higher in CT than in RT and NT. Crop rotation also increased the content of starch in the grain, as well as that of phosphorus (P), calcium (Ca) and iron (Fe), with respect to monoculture. Triticale grain from the CT plots contained more starch, magnesium (Mg), manganese (Mn) and iron (Fe) than grain from RT and NT. Crude fibre content, however, was higher in the grain harvested from the monoculture than in the case of crop rotation. Higher fibre content was also noted in the grain from NT and RT than from CT.
