Effect of Different Spacing and NPK Combination on Plant Growth, Fruit Yield and Fruit Quality of Strawberry (Fragaria ananassa Duch.) cv. Winter Dawn

The present investigation entitled “Effect of different Spacing and NPK (Nitrogen, Phosphorus, Pottasium) combination on plant growth, fruit yield and fruit quality of Strawberry (Fragaria ananassa Duch.) Winter Dawn” was carried out in the department of Horticulture, Prayagraj, Naini Agriculture Institute, Sam Higginbottom Institute of Agriculture, Technology and sciences, Prayagraj in the year 2023-2024. The goal of the experiment was to determine the best treatment combination for increasing farmer profitability and yield. A Factorial Randomized Complete Block Design including three replications and twelve treatment combinations was used to set up the experiment. The treatments consist of varying spacing combined with various NPK concentrations. Result obtained in present investigation showed that the treatmentT8(25×45cm+125:160:110NPKkg/ha) was determined to have the finest growth features, including petiole length (12.04 cm), plant spread (32.55 cm), plant height (14.91 cm), and number of leaves (16.33). In terms of fruit quality and yield, T5 (25 x 30 cm + 100 x 120 g NPK kg/ha) was found to be the best. These factors included the number of flowers per plant (12.13), the number of days it took for a fruit bud to develop (60.87 days), the number of fruits per plant (9.53), fruit set (79.33%), the weight of the fruit (32.81 g), the length diameter (1.56 cm), the fruit yield per plant (176.15 g), the fruit yield per plot (1.17 kg), TSS (9.98 brix), the pH of the juice (3.53), and the acidity percentage (0.67%). T3 had the lowest observation, (25 x 15 cm and +125:160:110 NPK kg/ha).
