Vegetative parameters of new plants of golden currant (Ribes aureum) in mulched and non-mulched plots

K. Kampuss
Two cultivars of the golden currant (Ribes aureum) - 'Laila' and 'Uzbekistanskaya Krupnoplodnaya' - were planted at Latvia University of Life Sciences and Technologies, Jelgava, in August 2017 in 2-factor experiment in 3 repetitions. Pine tree bark mulch in 10 cm depth was laid on mulched plots, and mechanical weed control was applied to the unmulched plots. The aim of this trial was to establish influence of soil mulching to vegetative parameters of new plantation of golden currants. May, June and August of the vegetation season 2018 had much higher water loss from soil than water supply, and even water supply in July and September, though close to balance, was very likely not enough to cover deficit from previous periods. This situation allowed to evaluate mulching effectiveness as soil moisture retaining mean and plant reaction to the different drought stress levels. Researched golden currants cultivars had potential for yielding in very early plantation age - flowering was observed a year after planting. Mulching of soil maintained water in soil effectively for a limited time, but after prolonged dry period soil water contents drop as low as for unmulched plots. Despite this, the golden currants even in the drought stress situation showed good vegetative growth, thus supporting they are drought resistant also in early plantation age. Golden currants in our experiment had tendency to form secondary growth and flowering after the stress situation.
