Tomato (Solanum lycopersicum) is one of the most significant vegetable crops in the world, due to increasing demand. To promote the availability of boron to the plant throughout crucial growth phases, which eventually leads to increased plant growth and greater yields, foliar boron spray is intended to promote plant growth and yields in summer tomatoes. For tomato plants, boron is a key component, and deficits can cause stunted growth, substandard fruit development, and lower yields. By giving the plant an easily accessible supply of the nutrient, boron application on the leaves can assist in addressing boron shortages in the plant. BARI Tomato-4 in the Bangladeshi district of Noakhali, we used four treatments, B0 (control), B1 (H3BO3 125 ppm), B2 (H3BO3 150 ppm) and B3 (H3BO3 175 ppm) so as to find out what factors have a substantial impact on summer tomato growth and output. Following those treatments produced the highest plant height (153.66cm), number of branches per plant (10.66), no. of clusters per plant (7.66), no. of flowers per cluster (8.33), weight of each fruit (83.66 gm), number of fruits per plant (34.33), and yield (22.43 tone) (H3BO3 150ppm). Treatment T0 (control) produced the lowest plant height (143.33 cm), number of branches per plant (6.66), number of clusters per plant (6.66), number of flowers per cluster (6.67), weight of each fruit (79.33 g), number of fruits per plant (31) and yield (21.33 tons), followed by treatments B1 (H3BO3 125 ppm), B2 (H3BO3 150 ppm), and B3 (H3BO3 175 ppm). In our study showed that development and productivity of summer tomatoes, growers higher by the use of boron at 175 ppm.
