Abstract

In a long-term experiment, the fertilizer response of 10 maize hybrids of different genotypes was studied on chernozem soil in a favourable year. The yields of the hybrids varied between 9500 and 18600 kg ha-1 depending upon the fertilizer treatment and the genotype. The excellent nutrient and water management of the chernozem soil was proved by the high yield (9500 – 14600 kg ha-1) obtained in the control. Even in such a good soil, the maize hybrids demanded fertilization and responded to it with a high yield increasement (3200 – 6500 kg ha-1). From among the tested hybrids, 8 hybrids gave the highest yield in the N120+PK treatment, while 2 hybrids reached their maximum yield in the N150+PK fertilizer treatment (13500 – 18600 kg ha-1 depending upon the hybrid). The water utilization of maize was improved as a result of the optimum fertilization. The water-use efficiency (WUE) was 30.35 kg mm-1, while it increased to 42.22 kg mm-1 at the optimum fertilizer dosage (N120+PK). The natural nutrient utilization ability (yield in the control treatment) and the yield obtained at the optimum fertilizer dosage (N120+PK and N150+PK) were used in a special coordinate system.
