Experiments with a view to establishing the biological value of different preceding crops such as clover, lucerne, vetch-oats mixture for winter wheat and their influence as well as the influence of green manure on the yield and it's quality were carried out at the Joniskelis Research Station over the period 1996-1998 on a heavy loam soil. Results of the trials showed that lucerne and clover left the largest amount of plant residues and nutrients, winter wheat as a preceding crop left in soil the smallest amount of residues with a low content of nutriet. The highest yield of winter wheat was obtained after lucerne, and the lowest after vetch-oats mixture. In general, the yields were posityvely affected by soil manuring. The amount of crude proteins in grains of winter wheat was under the influence of nitrogen content in preceding crop residues and manure
