<p>The present investigation was undertaken based on the hypothesis that exogenous application of specific plant growth regulators can significantly enhance vegetative growth, yield and fruit quality of strawberry cv. ‘Camarosa’ under protected conditions. A&#xa0;field experiment comprising 10&#xa0;treatments of plant growth regulators—gibberellic acid (GA₃) @ 25, 50, 75 ppm; naphthalene acetic acid (NAA) @ 5, 10, 15 ppm; benzyl adenine (BA) @ 5, 10, 15 ppm and control (water spray)—was laid out in a&#xa0;randomized block design with three replications under protected conditions. The results demonstrated a&#xa0;strong positive correlation between fruit weight and fruit yield, total soluble solids (TSS), reducing sugars and total sugars, while leaf area showed a&#xa0;positive association with fruit size, chlorophyll content and photosynthetic rate. Among all treatments, GA₃ @ 75 ppm proved significantly superior, enhancing fruit set (21.80%) and yield (126.30%) over control. It recorded the highest number of fruits (26.23), fruit length (42.44 mm), fruit weight (14.80 g), yield (388.03 g/plant), TSS (10.03 °Brix), total sugars (8.43%), ascorbic acid (65.67 mg/100 g) and anthocyanin content (0.23) (<i>p</i> ≤ 0.05). The findings establish that foliar application of GA₃ @ 75 ppm at 30&#xa0;and 60&#xa0;days after transplanting markedly improves growth, productivity and fruit quality of strawberry cv. ‘Camarosa’ under protected cultivation. In practical terms, this treatment offers a&#xa0;reliable and economically promising strategy for growers aiming to maximize yield and enhance marketable fruit quality in sub-temperate regions. The pronounced improvement in both quantitative and qualitative parameters strongly supports the commercial adoption of GA₃ @ 75 ppm as an effective growth regulator for high-value strawberry production under protected conditions.</p>
