Effects of foliar spraying of silica (Si) and potassium (K) nanoparticles were investigated on the leaf and fruit attributes of olive cultivar ‘Zard’. K nanoparticles (0, 400, and 800 mg.l-1) and Si nanoparticles (0, 30, and 60 mg.l-1) were applied via spraying on olive tree cv. ‘Zard’ at two distinct points within the growing season: early May and early July. A factorial experiment based on the completely randomized block design with three replications was conducted. The leaf characteristics of tree and fruit fresh and dry weight, fruit pulp to stone ratio, fruit dimension, as well as K and Si content of fruit and leaf were measured. According to the results, the majority of the studied traits were significantly influenced by the foliar application of Si and K. The application of Si and K nanofertilizers enhanced the leaf area index, with the greatest leaf length observed in trees treated with of 400 mg.l-1 K and 30 mg.l-1 Si. Our findings demonstrated that both K and Si treatments improved fruit characteristics, however, the impact of k treatment was more prominent than that of Si. Among the treatments, the combined application of 800 mg.l-1 K and 60 mg.l-1 Si resulted in superior fruit characteristics. The content of Si and K in the leaves and fruits were substantially affected by foliar spraying. Altogether, the results of this investigation demonstrate that there are strong synergistic effects between Si and K. Consequently, the simultaneous application of these two elements is recommended for enhancing olive tree yield.
