Abstract:
An experiment was accomplished in the Horticulture farm of Sher-e-Bangla
Agricultural University, Dhaka during the period from October 2017 to March
2018 to evaluate the bio efficacy of spore concentration of Trichoderma
harzianum on tomato. Three tomato variety viz. V

= BARI
Tomato-2, V

= Apple Netherland, and Trichoderma harzianum T

spores/ ml, (7 and 15DAT), T
= 10⁷
spores/ml (7 and 15DAT) were used in this experiment arranged in a
Randomized Complete Block Design with three replications. Data on different
growth and yield attributes parameters were taken in which all the treatment
showed significant variations. Among varieties, maximum plant height (111.2
cm), cluster number (7.6/plant), flower number (52.6/plant) and yield/ plant
(2.9 kg) were found from variety V
(Roma VF) whereas minimum in variety
V

(BARI Tomato-2) and among Trichoderma application, maximum plant
height (110.6 cm), cluster number (7.4/ plant), flower number (54.2/ plant)
yield/ plant (2.9 kg) found in spore concentration 10

/ ml (T
). Maximum yield
per hectare (91.5 t) were found in V

and minimum (84.7 t) in V
.
Chlorophyll content showed significantly positive correlation with all growth
and yield parameters. In view of overall performances, Variety V
spores/ ml Trichoderma harzianum (T
) solution application has potentiality
for increased tomato production.
