ABSTACT Cow slony was incorporated into land at levels equivalent to 0, 125, 250 or 500 t/ha (0, 50, 100 or 200 tons/ac) shortly before sowing maize (INRA 200). Quantity and quality determinations were made on the crop at 73, 93, 115 and 137 days after plant emergence. The slurry dressings delayed the emergence of maize plants. The 250 t/ha (100 tons/ac) treatment gave a significant increase in DM yield at the final harvest, but 500 t/ha (200 tons/ac) tended to depress yields of the whole crop and of the ear. There was no significant effect on the percentage DM of the crop. Slurry applications increased the level of E and nitrate‐N in the plants, but depressed Mg. Crude protein and in vitro digestibility were not affected.
