Abstract:
The field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka
during October 2017 to April 2018 to find out the response of humic acid and salicylic
acid on growth and nutritional quality of tomato. Four different doses of humic acid
viz., H
0
= 0 ppm, H
1
= 20 ppm, H
2
= 40 ppm, H
3
= 80 ppm and four doses of salicylic
acid viz., S
0
= 0 ppm, S
1
= 30 ppm, S
2
= 70 ppm, S
3
= 110 ppm were used to conduct this
experiment. The experiment was laid out in Randomized Complete Block Design
having two factors. Humic acid and salicylic acid showed significant variations with
most of the parameters studied. The maximum number of flowers per plant (38.58),
number of fruit per plant (27.42), yield of fruits per plant (2.90 kg) were found at 80
ppm humic acid treatment while the lowest result found in control. The maximum
number of flowers per plant (38.12), number of fruit per plant (27.83) and yield of
fruits per plant (2.95 kg) were found in 70 ppm salicylic acid
treatment. The highest
total sugar (4.40%), sodium (8.20%) and lycopene content (5 mg/100g) in fruit were
found in 80 ppm humic acid with 30 ppm salicylic acid. The highest yield of fruits per
hectare (94.07 tones) was obtained from 80 ppm humic acid with 70 ppm salicylic
acid treatment. So, the application of 80 ppm humic acid with 70 ppm salicylic acid
would be the best option to maintain better growth and to have better quality tomato.
