Abstract

Research was carried out at Lovely Professional University, Horticulture farm, Punjab (India), throughout 2022-23 to ascertain the impact of nanofertilizers (zinc oxide (ZnO) and iron oxide (FeO)) at different concentrations on various parameters of strawberry. The trial was conducted in a randomized block design and replicated thrice with 16 treatments. Findings of the research depicted that among all the different treatments, combined applications of ZnO and FeO nanoparticles (NPs) @150 ppm, that is, T15 Z3F3 (150 ppm ZnO + 150 ppm FeO) followed by T11Z2F2 (100 ppm ZnO + 100 ppm FeO) demonstrated significant effectiveness across various parameters of crop’s growth, flowering, and yield. During plants’ initial growth stage, measurements were maximum in T15 (150 ppm ZnO + 150 ppm FeO) compared to other treatments. T11 (100 ppm ZnO + 100 ppm FeO) followed closely behind T15 in terms of crop growth, e.g., plant height (7.3 cm) at 90 days after transplanting (DAT), number of leaves (15.00) at 110 DAT, leaf length (5.7 cm), chlorophyll content (55.47 μmol/m2), stem girth (7.67 mm), and petiole length (22.99 cm) parameters. Besides this, the flowering, e.g., the number of flowers per plant (11.00), duration of flowering (55.00), and yield, e.g., the number of fruits per plant (9.67), yield per plant (299 gm), number of harvesting (6.00) parameters were also observed higher in T15 (150 ppm ZnO + 150 ppm FeO). The impact of varying concentrations of ZnO and FeO NPs on the growth, flowering, and yield of strawberry (Fragaria × ananassa Duch) cv. Winter Dawn is investigated in this study. The dose concluded combined application (foliar) of ZnO and FeO NPs at the concentration of 150 ppm depicts significant results under the Punjab region of India concerning strawberry crop cv. Winter Dawn.
