| Abstract:
Results are presented from an organic plum orchard in Western Norway. The cultivar ‘Jubileum’ gave higher yield than cultivars ‘Souffriau’, ‘Victoria’ and ‘Reeves’ (trial on rootstock ‘Saint Julien A’) and ‘Avalon’ was more productive than ‘Excalibur’ (trial on rootstock ‘Pixy’). Degrading of fruits due to damages was on a low level in plums compared to results from organic apple and pear orchards. A fully acceptable level of first class plums was harvested. The highest figures for degraded fruits were found in ‘Victoria’, mainly due to internal gummosis. ‘Jubileum’ was found to be susceptible to fruit rot and is not recommended for organic production. | |
