o:5098 Production of walnut grafts under controlled conditions and plants development in the nursery en Abstract: Walnut grafting success under controlled conditions and the effect of foliar fertilization on the vegetative growth of walnut nursery plants were studied in this experiment. The study involved four cultivars and selections of walnuts, including ‘Šeinovo’, ‘Šampion’, ‘Elit’, and ‘G-139’. The experiment included two parts. The first was conducted under controlled air temperature and humidity conditions with three different Treatments (Treatment 1 - grafting without paraffin treatment of the scion and graft union; Treatment 2 - grafting involving paraffin treatment of the scion and Treatment 3 - graft union covered with sawdust, and grafting involving paraffin treatment of the scion and graft union covered with sawdust and foil). The best results on the parameters tested were obtained in Treatment 3 involving dipping the graft into paraffin and graft covering with both sawdust up to the scion and polyethylene foil. The second part involved research in the nursery and included four treatments (Treatment 1 - without foliar fertilisation and Treatments 2, 3, 4 - with foliar fertilisation (Nitrophoska foliar, Nitrophoska solub and Humisol, respectively). Walnut plants treated with Humisol had a significantly higher survival rate in the first year, greater height and diameter in both years, as well as a higher percentage of first-class plants at the end of the second year compared to other treatments.
