Performance of seven blackcurrant cultivars under two soil maintenance systems
Blackcurrant is one of the main berry crops grown in Latvia, however, the obtained yields are low. Cultivars and cultivation practices can play a big role in increasing productivity. The aim of this research was to evaluate seven blackcurrant cultivars: Gagatai, Iyunskaya Kondrashovoi, Kriviai, Selechenskaya, Svita Kiyevskaya, Vernisazh and Titania using two growing practices: with application of pine bark mulch, and without mulching where herbicides were applied in rows. The trial was established in 2010 at the Pūre Horticultural Research Centre, Latvia. The planting distance was 3.0 m between the rows and 1.0 m between the bushes in the row. Randomized split block design with four replicates was applied. Plant vegetative growth, phenological parameters, winter hardiness, yield, fruit quality, incidence of pests and diseases were evaluated during the years 2012-2016. Gagatai, Vernisazh and Selechenskaya were the most productive among evaluated cultivars and characterized by good adaptability for growing in local conditions. No significant differences were stated in blackcurrant phenological development, productivity and fruit size among both growing practices that were evaluated. However, the application of pine bark reduced the growth of weeds, and plants were less damaged by leaf spot diseases and aphids in comparison to growing without mulching.
