Investigating the Synergistic Effects of Biofertilizers, Micronutrients and Biostimulants on Fruit Quality of Strawberry Cv. Nabila

Abstract

Strawberry (Fragaria × ananassa) is a high-value fruit crop with substantial economic and nutritional benefits. This study assesses how nutrient and biostimulant management influences the quality of strawberry cv. 'Nabila' grown in the Nilgiris of TamilNadu. A factorial experiment was carried out to evaluate the effect of combinations of biofertilizers, micronutrients, and biostimulants on fruit quality parameters of strawberry. The findings revealed that treatments including Arbuscular Micorhizal Fungi (AMF) and potassium-solubilizing bacteria (KSB), as well as a micronutrient mix (0.6%) with humic acid (1%) and seaweed extract (1%), greatly increased fruit production and quality. This combination resulted in higher total soluble solids, total phenols, and titratable acidity. An integrated nutrient management strategy, incorporating AMF and KSB in combination with micronutrients and biostimulants such as humic acid and seaweed extract, presents a promising approach to improving both the quality and post-harvest attributes of strawberries. Additionally, the adoption of such a bio-enhanced fertilization approach promotes soil health, reduces reliance on synthetic inputs, and aligns with environmentally sustainable agricultural practices.
