Abstract
A small plot field experiment was established to examine the hybrid-specific effects of split N fertilisation and irrigation on chernozem soil with calcareous deposits on the Hajdúság loess ridge. We tested the effect of different rates of the optimum 75 kg N/ha N rate established in our previous experiments at the given site. Irrigation increased the height of both hybrids in all treatments by an average of 13.0 cm. There was no statistically confirmed difference in leaf area between irrigated and non-irrigated hybrids. The different nutrient responses of the hybrids are shown by the fact that all nitrogen split treatments resulted in yield increases (7.5–17.5%) for the Tyson hybrid, whereas Dessert R78 yielded 1–7.9% less than the control in two treatments. The irrigation response of the two genotypes was different, with Dessert R78 yielding 2868 kg and Tyson 2066 kg more than the non-irrigated treatment, averaged over the fertilisation treatments.
