Results from an international stationary field trial (ISDV) have been analyzed for effects of increased nitrogen doses on yield of corn. The trial has been established on a calcareous chernozem soil, at Rimski Sancevi experiment field of the Institute of Field and Vegetable Crops, Novi Sad (Serbia). The average yield of grain obtained in the variants with plowed under harvest residues was 12.22 t/ha. It has higher by 1.02 t/ha or 9.1% than the average yield obtained in the fertilizer variants that received no harvest residues. On average for both analyzed hybrids, the highest average yield (12.76 t/ha) was achieved in the fertilization variant with 150 kg/ha of nitrogen combined with plowing under harvest residues. On average, the yield of the hybrid NS 6010 was highly significant as compared with that produced by the hybrid NS 510.
