Abstract:
A pot experiment was conducted at the net-house of Sher-e-Bangla Agricultural University,
Dhaka, during the period from October 2015 to March 2016 to investigate the effect of
modified chitosan on seedling morphological characters, growth and reproductive characters
and yield performance of tomato cv. BARI tomato-15. The experiment was designed with
five treatments using four level of modified chitosan in the seedbed soil (10 kg of soils per
pot). The used treatments were T
1
modified chitosan/pot), T
4
(control), T
2
(50 g modified chitosan/pot), T
3
(150 g modified chitosan/pot) and T
5
(100 g
(200 g modified
chitosan/pot). The experiment was laid out in earthen pots arranged in a randomized
complete block design (RCBD) with three replications. Application of modified chitosan
increased seedling height, fresh and dry weight of seedlings, soil pH, organic carbon (%),
organic matter (%), number of flowers/ plant, fruits/plant, fruit size and fruit yield over
control. Most of the morpho-physiological, reproductive and yield attributes were increased
with increasing doses of modified chitosan, whereas control plants showed the lowest value
of the above parameters. Most of the morphological, growth and reproductive attributes were
recorded maximum in the T
4
and the highest fruit yield was recorded in the T
5
might be due to the morpho-physiological changes and increased number of fruits/plant.
Therefore, application of modified chitosan at 150g or 200g/pot (10 kg soils) could be used
for getting quality seedling, leading to maximizing the tomato fruit yield.
