Abstract:
Chitosan raw material powder has many uses to plant nutrient supply and modifies
growth, yield and yield attributes of plants. An experiment was conducted at the
research farm of Sher-e-Bangla Agricultural University, Dhaka, during the period from
November 2018 to March 2019 to study improvement of tomato yield and soil
properties using chitosan raw material powder. The test crop was BARI Tomato-15.
Five levels of chitosan raw material powder were used in the experiment viz.T
1
: 0 t/ha,
T
2
: 0.5 t/ha, T
3
: 1.0 t/ha: T
4
: 1.5 t/ha and T
5
:2.0 t/ha. The experiment was conducted
using Randomized Complete Block Design (RCBD) with four replications. The results
of the experiment revealed that plant height (cm), number of fruit clusters/plant, number
of fruits/plant, Individual fruit weight (g), fruit yield (t/ha) were significantly influenced
by the effect of chitosan raw material powder. Most of the morphological and yield
attributes were increased with increasing doses of chitosan raw material powder,
whereas control plants showed the lowest value of the above parameters. Maximum
fruit yield, number of fruits/plant, number of fruit clusters/plant and individual fruit
weight were found in the T
3
treatment; whereas the minimum result of those parameter
were obtained in the control, T
1,
treatment. Among the parameters plant height was
recorded highest in the T
5
treatment, lowest was in the control treatment, T
1
. The results
also showed that soil organic carbon content was increased significantly with the
application of chitosan raw material powder. The chitosan raw material powder was
alkaline in nature and increased pH of the post-harvest soil. Taken together, our results
indicate that application of chitosan raw material have positive role on the improvement
of tomato yield, yield parameters and SOC content. The results might be due to the
supply of some essential plant nutrients and growth promoting hormones.
