In field trials in Central Poland some cultural practice and mycorrhizal inoculation were evaluated for vegetative growth and yield of cranberry (Vaccinium macrocarpon Ait.) cv. 'Pilgrim'. The experiment was set up in autumn of 2004 and is still conducted. Plots were established at two soil treatment: one on mineral soil with low organic matter content (adjustment soil pHKCl to 4.0) and the other with additional organic matter (peat). Before planting one half of plants were inoculated with ericoid mycorrhizal fungi and the others – not. Also fertilizer trials were conducted at rates of 0, 20 and 40 kg.N haE-1yrE-1 on permanent plots. There were twelve treatments total. The plantation was irrigated with acidified water (pH 4.0-4.5). There were significant treatment effects for vegetative growth. Adding organic matter increased vegetative growth, in case of non mycorrhized plants; but not effected when mycorrhizal fungi were applied. In two years fruiting period there were not significant effects of soil, mycorrhizal inoculation and the rate of nitrogen on yield or mean fruit weight. Generally, the highest rate of nitrogen decreased yielding.
