Vpliv različnih pripravkov na vegetativno rast in pridelek jagod sorte 'Clery' (Fragaria x ananassa Duch.)

Turk, Anže (avtor), Štampar, Franci (mentor)

Na površinah, kjer se jagode pogosto sadi na isto mesto, je večji pojav talnih patogenih gliv in škodljivcev, ki povzročajo bolezni in poškodbe korenin in negativno vplivajo na pridelavo. Na trgu se v zadnjih letih pojavljajo pripravki, ki zmanjšajo vpliv fitopatogenih organizmov na rastline. Namen magistrske naloge je ugotoviti, ali je mogoče s temi pripravki zmanjšati negativni vpliv na pridelavo jagod. Poskus smo izvajali v letih 2020 in 2021 na kmetiji Jarkovič na območju kraja Brod v Podbočju. Imeli smo tri obravnavanja: kontrolo, kombinacijo pripravkov podjetja 'Atens' ('Team horticola', in 'Condor shield') in kombinacijo pripravkov podjetja 'L.G. Italia' ('Ken', 'Klozer', 'Sphera', 'Carbogen', 'Start' in 'Algalis'). Pripravke podjetje 'L.G. Italia' smo uporabili pred sajenjem jagod, pripravke podjetja 'Atens' pa po sajenju in kasneje med vegetacijo. Na vzorčenih rastlinah smo merili vegetativno rast in količino ter kakovost pridelka. Rastline, kjer so bili uporabljeni pripravki, so imele večjo dolžino in maso nadzemnega dela ter večjo maso korenin. Kot posledica boljše vegetativne rasti so rastline v obravnavanjih, kjer smo uporabili pripravke, imele 33 % več pridelka v primerjavi s kontrolo, plodovi so bili večji. Kakovostni parametri vsebnosti suhe snovi, trdote plodov, vitamina C, skupnih kislin, skupnih sladkorjev in skupnih fenolov je bila za povprečje vseh terminov večja pri kontroli. V nekaterih terminih, med obravnavanji ni bilo statistično značilnih razlik. Plodovi kontrole in obravnavanja pripravkov 'L.G. Italia' so dosegli prag odličnega okusa, obravnavanja pripravkov 'Atens' pa srednje dobrega okusa. Uporabljeni pripravki so pozitivno vplivali na boljšo vegetativno rast in pridelek. Zaradi večjega pridelka je rahlo upadla kakovost plodov, kljub temu pa so plodovi dosegli prag dobrega okusa. Glede na povečanje pridelka, ki ni bistveno slabše kakovosti, se je uporaba pripravkov pokazala kot zelo gospodarna.

Izvleček

Due to regular cultivation of strawberries in the same location, growers have encountered problems with soil-borne pathogens and pests in strawberry production. In recent years, new products with antagonistic or biostimulant activity have entered the market. The objective of this study was to evaluate the potential for reducing crop damage by using a combination of products. The experimental plot was established on the Jarkovič farm in Brod v Podbočju in 2020 and 2021. The trial was divided into three plots. The control plot was untreated, in the second plot products of the company 'Atens' ('Team horticola' and 'Condor shield') were used, and in the third plot products of the company 'L.G. Italia' ('Ken', 'Klozer', 'Sphera', 'Carbogen', 'Start' and 'Algalis') were used. The products of 'Atens' were used after planting during vegetation and the products of 'L.G. Italia' were used before planting. We measured vegetative growth, yield and quality of yield. Vegetative growth was better in the plots where the products were used, root weight and plant weight were higher. The treated plants had a 33% higher yield than the control plants, and the fruits were also larger. The content of dry matter, vitamin C, sugars, acids and phenols was higher in the fruits of the control plants, they also had firmer skin. The fruits of the control plants and of the plot 'LG Italia' reached a high taste quality, while those of the plot 'Atens' reached a medium taste quality. The products used had a good influence on vegetative growth and yield. However, due to the higher yield, the quality of the fruits was lower. Although the quality was lower, the fruits achieved the desired flavour. Higher yield with medium and high flavour quality means that the use of products is a good method to reduce soil pathogen problems in strawberry production and a solution for better farm management.
