The Effect of Soil Mulching on the Yielding of Hardy Kiwifruit Cultivars (Actinidia arguta) in Central Poland
(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Marosz, Adam; Research Institute of Horticulture, Skierniewice, Poland
Kiwiberry, or hardy kiwifruit (Actinidia arguta) is a new pomological plant in Poland. There are many possibilities for setting up an orchard with this species. However, Actinidia is susceptible to late spring frost. Summer irrigation for good fruit yielding is required. In this experiment the effect of soil mulching on the yielding of five cultivars of hardy kiwi fruit was observed. The orchard was started in 2005, but the experiment was conducted from 2010–2015, when plants were full fruiting. Half of the line of each cultivar was mulched with straw, the other half was treated with an herbicide. No additional summer irrigation was provided. Yielding of actinidia cultivars was very varied, but the results showed that straw soil mulching improved the fruit yield of all cultivars. The highest total and commercial yield was recorded for the cultivars: ‘Ananasnaya’, ‘Geneva’, and ‘Weiki’. Generally, the commercial yield of plants mulched with straw was higher; from 0.83 to 1.98 kg per plant compared to the control which had herbicide stripes along the rows. .
