    <abstract>Grass-clover leys are an integral part of organic rotations. We performed an&#13;
experiment with reduced tillage (RT) and conventional tillage (CT) using mouldboard&#13;
ploughing in a rotation in Frick (Switzerland) on a heavy soil and 1000 mm mean&#13;
annual precipitation. The grass-clover mixture was sawn in autumn 2005 after uniform&#13;
seed bed preparation with a rotary hoe in both tillage systems without ploughing. After&#13;
emergence most of the clover seedlings collapsed in the CT plots due to draught,&#13;
while they survived in the RT plots. This led to a much higher share of clover in the&#13;
mixture under RT. Grass-clover yields were 29 and 23% higher in RT than in CT plots&#13;
in the first and second year of cultivation in 2006 and 2007, respectively. Grass grown&#13;
in RT plots was higher in nitrogen (N), phosphorous (P), potassium (K) and&#13;
magnesium (Mg) content than in CT plots; clover contained solely more P in RT plots.&#13;
Over all grass-clover had better growing conditions in RT compared to CT plots in our&#13;
experiment, reflecting after-effects of the differentiated tillage schemes applied for the&#13;
preceding arable crops. It is suggested that reduced tillage has a high potential to&#13;
improve water stress tolerance of cropping systems.</abstract>
