The experiment was conducted in Garlica Murowana near Kraków in 1999–2001. Five living mulch treatments were investigated: white clover, mulch of white clover desiccated in mid July with Roundup, lucerne, mixture of living mulches of rye and clover, and rye, which were compared to two controls: the weeded and the twice–weeded. The living mulches were sown in the middle of April in 50 cm wide strips. Corn ‘Sweet Trophy F1’ was sown on 9th May in bare ground rows. The living mulches decreased the height of sweet corn plants. The effect of using mulches of rye and rye mixed with clover was highest, whereas that of clover lowest. In result of mulching morphological features of ear were worse: weight, length, diameter, kernel row number and ear feell. All mulches decreased marketable yield: clover by 21%, clover desiccated with herbicide by 26%, lucerne by 32%, mixture of rye with clover by 56%, and rye by 64% according to the control objects. Mulching with the mixture of rye and clover in comparison with clover alone caused deterioration of ear morphological features and yield lowering. Total sugars and starch content in kernels increased in the mulched objects.
