Impact of Nano-fertilizers and Nutrient Management on Growth and Yield of Strawberry

Abstract

In the pursuit of enhancing agricultural practices, this research delves into the intricate interplay between nano-fertilizers, nutrient management strategies, and their collective impact on the growth and yield metrics of strawberries. The present research was carried out to ascertain the impact of nano-fertilizers (ZnO and FeO) and integrated nutrients management (Phosphate solubilizing bacteria (PSB) & Azotobacter) on strawberry (Fragaria x ananassa Duch.) Cv. Winter Dawn. The results of present work showed different treatments of nano fertilizers and nutrients management has variable impact on strawberry growth such as treatment 7 (T7: 50% Recommended dose of fertilizer) + FYM + vermicompost + Azotobacter + 150 ppm nano-ZnO + 150 ppm nano-FeO) showed highest growth parameters regarding number of leaves (14), plant height (11.24 cm), leaf area (74.86 cm2) and chlorophyll content (52.41 μmol/m2) etc. compared with other treatments. However, treatment (T9: 50% RDF + FYM + vermicompost + Azotobacter + PSB + nano-ZnO + nano-FeO) indicated bit similar regarding number of leaves (13.33), plant height (11.96 cm), leaf area (74.08 cm2) and chlorophyll content (53.06 μmol/m2) etc. The biochemical parameters were also observed higher in treatment (T9). Considering above results, it can be concluded that the dose, i. e., 50% RDF along with FYM, vermicompost and Azotobactor + ZnO + FeO (150 ppm) could enhance growth and yield of strawberry.
