An investigation was carried out at experimental field, Department of Horticulture, Aromatic and Medicinal Plants, Mizoram University to study the effect of planting density on growth, yield and quality of strawberry(Fragaria × ananassaa Duch.) cv. Camarosa. The experiment comprises of a number of planting densities, viz. T1: 50 × 40 cm, T2 : 40 × 40 cm, T3 : 40 × 30 cm, T4 : 30 × 30 cm, T5: 30 × 25 cm, T6 : 25 × 25 cm, T7 : 25 × 20 cm and T8 : 20 × 20 cm and T8 : 20 × 20 cm. Among the different planting density, the maximum growth in terms of plant height (26.85 cm), E-W (37.83 cm) and N-S spread (39.58 cm), number of leaves (34.45), leaf area (213.92 cm2) and crowns/plant (8.11) were observed in the widest spacing, i.e. 50 × 40 cm. This treatment also exhibit superiority in yield attributing characters like berry set percentage (81.17), berry weight (21.73 g), berry diameter (36.06 mm), berry length (43.73 mm), number of berries/plant (21.05) and total biomass (964.64 g). The quality parameters of the fruit like TSS (8.94 °Brix), titratable acidity (0.812%), TSS: acid ratio (11.03), total sugars (8.50%), reducing (4.78%) ascorbic acid (67.67/mg/100g) and anthocyanin content (38.53 mg/100g) were also found superior in this spacing. The overall assessment of the present study concluded that a spacing 50 × 40cm is the most efficient planting denstity for improving growth, yield and quality in Camarosa strawberry under Mizoram conditions.
