abstract:
The field experiment was carried out in 2005-2008 at the Experimental Farm Uhrusk (University of Life Sciences in Lublin). Type of stubble crops (white mustard, fiddleneck, winter rapeseed, and mixture of legumes: narrow-leaved lupine + field pea) annually ploughed after the oats harvest were the experimental factor. The oat cv. Bajka was cultivated in monoculture. For three experimental years the effect of stubble crops on oats grain yield was not statistically proven, only a tendency to its increase on all plots with ploughed stubble crop mass with comparison to the control. In 2007 and 2008 statistically significant increase of oats grain yield in comparison to the no-stubble-crops object was noted after white mustard and mixture of legumes. In 2007 significantly higher yield of oats was also noted after fiddleneck in comparison to control. Average for the period of study has not proved the effect of the research factor on the yield of oats straw. Among the elements of yield structure, stubble crop only significantly modified the weight of 1000 grains. Average of the three years of the study, the best trait value was found after ploughing fiddleneck, after which the weight of 1000 grains was significantly – by 8.9% – higher than that obtained after winter rapeseed.
