Although the use of deficit irrigation is very valuable in effective water management, productivity losses are a significant problem. For this reason, this study investigated the effectiveness of using nanoparticle silica fertilizer produced as a result of nanotechnologies on pepper seedlings grown under deficit irrigation by applying it to the soil and leaf. The study was conducted with three replications in a completely randomized factorial experimental design in the climate room, with three irrigation water levels (I100: full irrigation, I75: 25% deficit irrigation, I50: 50% deficit irrigation) and three nanoparticle silica applications (Nc: non-nanoparticle silica applications, Ns: nanoparticle silica applications from soil, Nl: nanoparticle silica applications from leaf) in a total of 27 pots. As a result of the study, it was determined that plant height, stem diameter, root weight, number of leaves, leaf area, chlorophyll, and leaf relative water content of seedlings under deficit irrigation decreased and membrane damage increased, but nanoparticle silica was effective in improving these physical and physiological properties, except for the number of leaves, and nanoparticle silica application from leaf increased this effectiveness even more than soil application. In the light of these results, nanoparticle silica application from leaf was found to be advisable in growing pepper seedlings under deficit irrigation conditions, especially in regions where water resources are scarce, but it was also determined that it is important to contribute more to the literature on this subject.
