| Abstract:
Effects of the width of herbicide strips, N fertilisation, root type and 'Schattenmorelle' (Prunus cerasus L.) clone upon leaf nutrient content was studied in the years 1989–1992. Two 'Schattenmorelle' clones obtained from Bonn (No. 226 and 226/80) did not differ in the content of any element under study. Width of herbicide strips (3 m vs 1 m), at nil N fertilisation, had no effects on the nutrient contents. N was always within optimum range; which was apparently due to high soil organic matter content. Leaf N content was slightly reduced in the check (N - O) treatment, compared with N - 60, only in 1991. Self-rooted trees always contained less Mg and usually less Ca and Mn, compared with the trees on P. avium seedling rootstocks. Self-rooted 'Schattenmorelle' trees contained significantly more N and K than leaves of sour cherry trees grown on mazzard rootstocks; however in 1991 no effects of root type on leaf N or K was found and in 1992 leaf K of self-rooted trees was reduced. The results obtained confirmed that genetic factors and particularly kind of root system may play a more important role in cherry nutrition than fertilisation. On a good orchard soil, with a deep humic horizon and high organic matter content, apparently no N fertilisation is needed. | |
