The present study was aimed to assess the effect of chemical (N) and biofertilizer
(Trichoderma) on the growth and yield of tomato (Solanum Lycopersicum L.) and residual
nutrient contents in the post-harvest soil. The experiment was conducted at the research farm
of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2019 to
March 2020. The treatments included three levels of nitrogen (N) 0, 80 and 120 kg ha
and
four concentrations of Trichoderma (BF) 0, 1.5, 2.5 and 3.5 g kg
-1
soil. Nitrogen influenced
the growth and yield contributing characters of tomato. The plant height, 1
flowering date,
number of leaves plant
-1
, flowers plant
-1
, fruits pot
-1
, fruits plant
-1
st
, dry matter weight plant
and yield were the higher when 120 kg N ha
-1
was applied. In case of Trichoderma
treatments, higher plant height was obtained in BF
3
treatment (3.5 g kg
-1
-1
soil) whereas the 1
flowering date, number of leaves plant
-1
, flowers plant
-1
, fruits plant
-1
, fruits pot
were found higher in BF
2
(2.5 g kg
-1
soil). The maximum dry matter weight plant
was
found similar in both BF
2
and BF
3
treatments. The combination of N and BF also exhibited a
significant variation in yield attributes, vegetative growth, dry matter weight and yield. The
higher plant height, number of leaves plant
-1
, dry matter weight plant
-1
-1
, yield pot
, flowers plant
, fruits
plant
-1
and fruits pot
-1
was found in N
2
BF
2
treatment (120 kg N ha
-1
and 2.5 g kg
soil
Trichoderma) compare with other combined treatments. The same combined treatments also
showed the higher soil organic carbon content, total Nitrogen, available Phosphorous and
Sulphur in post-harvest soil. As this combined effect (120 kg ha
-1
N + 2.5 g kg
soil
Trichoderma) promote growth, yield and yield attributes of tomato and maintain maximum
residual nutrients, therefore, N
2
BF
2
could be best treatment combination.
