Abstract
The results of two different topics within the research project “Increasing crop safety and optimizing of crop loading of organic grown pome fruit” (FKZ 06OE197) founded by BOLN at the research institute LVWO Weinsberg, Southern Germany, are presented in this abstract. Potassium fertilisation of soil (2 x 80 kg K2O/ha) as well as spraying boron on the flowers and leaves three times during the blossom (total 2.5 kg B/ha) improved fruit setting and yield. With potassium and boron fertilisation more fruits smaller 60 mm were counted, furthermore with boron more small fruits were counted, too. Another topic was the reaction of five pear cultivars on different organic spraying strategies. Some organic fruit growers were under the impression that often a reduction of fruit-setting could be caused by use of sulphur. Results of this part of trials could not confirm this in every case, but clear reactions of cultivars, especially of ‘Conference’, on sprayings with wetting sulphur or lime sulphur were seen at evaluation of russetting of the fruits. Altogether the cultivar ‘Uta’ showed a good yield, but the worst compatibility of the leaves with the tested organic spraying strategies. ‘Gerburg’ had good yields, too, but seemed to be moderately susceptible for pear-scab in 2013.
