Abstract:
The growth, yield and quality of tomato largely depend on soil and climatic conditions and
also on BARI Tomato 14. Among these, proper application of plant growth regulators and
B plays a vital role.A field experiment was conducted at Sher-e-Bangla Agricultural
University Farm, Dhaka, Bangladesh during October 2017 to April 2018 to evaluate the
effect of foliar application of IBA, GA
and B on yield and quality of tomato. Single variety
BARI Tomato-14, and foliar application of IBA 5ppm, GA
3
5ppm and B 2mg/L were used
to conduct this experiment. The experiment was laid out in a Randomized Complete Block
Design (RCBD) having single factor and replicated three times. Data were collected on
plant height, number of leaves plant

, number of branches plant
-1
, Leaf Area Index(LAI),
chlorophyll content of leaf, number flowers cluster pant
-1
, number of fruit plant
, weight of
fruit, yield hectare
-1
, Vitamin-C content and TSS% content. A statistically significant
variation was recorded in terms of all the characters related to growth and yield quality of
tomato. The maximum plant height, number of branches plant

, length of branch
respectively 103.03 cm at 90 DAT, 65.70 at 90 DAT, 13.11 at 90 DAT was observed in
treatment of T
