Abstract:Za preučevanje vplivov različnih načinov gnojenja na polično kakovost malin je bil v letu 2019 izveden poljski poskus v nasadu malin sorte 'Himbo Top'. Uporabili smo tri vodotopna kristalinična gnojila (Solinure 20-20-20 + TE, Hakaphos Violeta 13-40-13, Novatec Solub 14-8-30), aplicirana v različnih fazah rasti preko fertirigacije, ter biostimulator Vitanica Si, apliciran foliarno ob vsakem gnojenju. Osnovno gnojenje je bilo opravljeno s peletiranim hlevskim gnojem (20 kg N/ha). Poskus je temeljil na štirih obravnavanjih: kontrola (20 kg N/ha – brez fertirigacije in namakanja), obravnavanje 2: standard (60,9 kg N/ha), obravnavanje 3: standard + 50 % mineralnega dušika 81,37 kg N/ha ter obravnavanje 4: standard + 50 % N ter biostimulator − 81,48 kg N/ha. V poskusu smo spremljali generativne parametre, kemijsko sestavo plodov ter njihovo polično kakovost. Večji odmerek dušika je imel za posledico večjo povprečno maso plodov, negativni vpliv na vsebnost topne suhe snovi ter spremembo okusa; hkrati večji odmerek dušika zmanjša polično kakovost plodov (vrednoteno preko izgube mase pridelka in pojava bolezni). Biostimulator (Si) ne prispeva k izboljšanju parametrov kakovosti, saj ne zajezi negativnega trenda izgube mase in volumna pridelka ter ne zajezi plesnenja plodov kot posledice uporabe večjih odmerkov dušika.
Keywords:maline, dušik, gnojenje, polična, kakovost.

Title:Effects of different fertilisation methods on raspberry (rubus idaeus l.) cv. 'himbo top' (rafzaqu) shelf life
Abstract:A field trial was conducted in 2019 to assess the effects of different methods of fertilisation on raspberry (Rubus idaeus L.) cv. 'Himbo top' (Rafzaqu) shelf life. Three different water-soluble crystallinic fertilizers (Solinure 20-20-20 + TE, Hakaphos Violeta 13-40-13, Novatec Solub 14-8-30) were administered in different growth phases by means of fertigation, with a simultaneous addition of a plant biostimulant Vitanica Si administered foliarly. In spring, pelleted manure was spread between the rows in a single dose of 20 kg/ha. The experiment consisted of four different treatments: control (20 kg N/ha – without fertigation or irrigation), treatment 2: standard (60,9 kg N/ha), treatment 3: standard + 50 % mineral nitrogen – 81,37 kg N/ha and treatment 4: standard + 50 % mineral nitrogen and biostimulator – 81,48 kg N/ha. The following parameters were monitored: generative parameters, fruit chemical composition and fruit shelf quality. In fruit of plants fertilised with more nitrogen an increase in average weight and a decrease in the content of soluble solids and poorer taste quality were observed. A larger dose of nitrogen decreased the shelf quality of the fruit (observed in larger average weight loss and mold incidence). The added biostimulator was not effective in limiting the negative trends of fruit weight and volume loss as well as the limiting of the development of mold caused by the larger doses of nitrogen and therefore did not contribute to the improvement of the observed quality parameters.
