ABSTRACT
A field experiment was conducted at the Horticulture Farm in the Department of Horticulture, Bangladesh Agricultural University, Mymensingh to evaluate the influence of different levels of 4-chlorophenoxy acetic acid on growth and yield potential of tomato during summer. The two-factor experiment viz., Factor A: four different concentrations of 4-chlorophenoxy acetic acid (4-CPA) i.e., concentrations of 4-CPA were (i) 0 ppm (without 4-CPA), (ii) 20 ppm, (iii) 40 ppm and (iv) 60 ppm; and Factor B: two varieties of summer tomato namely, BARI Hybrid Tomato-4 and 8. The experiment was laid out in randomized complete block design with three replications. At harvest, the tallest plant (78.53cm), number of flowers and fruits (35.11and 18.10, respectively) plant-1, fruit yield plant-1 and ha1 (1.12 kg and 21.98 tons, respectively) were found in BARI Hybrid Tomato-8. At harvest, the maximum plant height (85.57 cm), number of flowers and fruits (44.89 and 24.97, respectively) plant-1, fruit yield and ha-1 (1.32 kg and 27.78 tons, respectively) were found when 4-CPA applied at 60 ppm, whereas the minimum for these characters were recorded from control plants. In case of combined effect of variety and plant growth regulator, the maximum plant height (88.90 cm), number of flowers and fruits (40.04 and 21.99, respectively), fruit yield plant-1 and ha-1 (1.34 kg and 28.28 tons, respectively) were observed in BARI Hybrid Tomato-8 when treated with 4-CPA at 60 ppm, and the minimum for all these characters were found in control plants. The results of the present study suggest that 4-CAP at 60 ppm can be practiced for increasing summer tomato production for both the varieties.
Key words: Plant growth regulators, growth, fruit set, yield and summer tomato
