Comparison Strawberry Field Production and Occurrence of Grey Mould at Strawberry Growing on System with Addition of Apple Tree Woody Chips

摘要

In the years 2014 to 2016 the influence of apple tree wood chips and composted apple tree wood chips in which oyster mushroom grew and yielded which were supplemented into soil on strawberry field production and occurrence of grey mould at strawberry (cv. ‘Sonata’) was evaluated. Average weight and number of fruits per plant, average fruit weight, average weight and number of fruits affected by Botrytis cinerea per plant, percentage of weight and number of fruits affected by Botrytis cinerea was calculated. There were recorded differences concerning strawberry yield among the investigated variants of plots, but mainly there were not statistically significant. In 2015 and 2016 the highest average weight of yield and the highest number of fruits was reached at plants cultivated on plots with apple tree wood chips. Average weight of yield on plots with apple tree wood chips was 663.72 g and 822.41 g in 2015 and 2016, respectively. Number of fruits per plant on plots with apple tree wood chips was 67.88 pieces and 65.29 pieces in 2015 and 2016, respectively. Occurrence of grey mould caused by Botrytis cinerea on all variants of plots was similar and small differences was found out only but statistically significant difference was among the years. Grey mould was the most frequently found out in the year 2016. B. cinerea affected 48.27, 56.89 and 55.94 grams of fruits per plant from plots with composted apple tree wood chips, plots with apple tree wood chips and control plots in 2016, respectively.
