Eco-Nanotechnology Approach to Improve the Growth and Fruit Quality of Strawberry Through Nano Boron and Copper Applications

Strawberry is botanically a berry-like fruit in the genus Fragaria of the Rosaceae family. Strawberries are important for human health because they are a rich source of vitamin C, along with potassium, iron and comprehensive antioxidants. In order to study the effect of foliar application of nano boron and copper on vegetative growth and reproductive characteristics of strawberry c.v camarosa were investigate.

A factorial experiment in a completely randomized block design with 3 replications which the factors included Nano Boron at three levels (0, 10 and 20 ppm) and Nano Copper at three levels (0, 20 and 40 ml L^-1). The experiments have been done on fall season 2024.

The results showed that the highest concentrations of both Nano Boron (20 mg.L^-1 and Nano Copper (40 mg.L^-1) significantly enhanced several key growth parameters, including total leaf area, chlorophyll content, number of leaves per plant and leaf dry matter percentage. Additionally, the combined application of 20 mg.L^-1 Nano Boron and 40 mg.L^-1 Nano Copper produced the most favorable outcomes in yield components, such as fruit volume (29.78 cm³), fruit weight (21.93 g), total soluble solids (6.533%) and sugar content, while simultaneously reducing total titratable acidity. Enhanced anthocyanin accumulation was also observed in the same treatment, indicating improved fruit quality. The synergistic interaction between Nano Boron and Nano Copper appears to promote photosynthetic efficiency and metabolic activity, contributing to overall yield and fruit biochemical enhancement. These findings support the use of Nano Boron and Nano Copper as sustainable and eco-friendly agents for improving strawberry productivity and quality, particularly in cultivars grown under suboptimal conditions.
