Abstract:
The experiment was conducted in the experimental field of Sher-e-Bangla
Agricultural University thrm, during the period from December 2008 to March
2009 to find out the effect of
zinc
and molybdenum on the yield and quality of
tomato. The experiment consisted of two factors as A (Four levels of Sc): Zn
0: 0
kg Zn/ha. Zn
3
: 3 kg Zn/ha, Zn
6
: 6 kg Zn/ha, Zn
9
: 9 kg Zn/ha, and B (Four levels of
Molybdenum): M
0
: 0kg Mo/ha, Mo
05
: 0.5 kg Mo/ha. Mo
1•0
: 1.0 kg Mo/ha, Mo
15:
1.5 kg Mo/ha. In case of zinc treatment, plant height, number of leaf, number of
flower cluster, number of flower, number of fruit, single fruit weight, vitamin-C
content and yield increased significantly with increasing Zn level up to 6 kg Zn/ha
9).
The maximum plant height (63.63), fruit number (44.17), vitamin-C content
(Zn6
) whereas vitamin-A content increased significantly up to 9 kg Zn/ha (Zn
(17.52 mg/ I OOg) and yield (44.26 tlha) were recorded from Zn
6
treatment. The
maximum vitamin-A content with Zn
9
was (6444.0 .tg/100g). The maximum zinc
(361.50 ppm) uptake was recorded from Zn
9
treatment and the minimum zinc
(190.3 ppm) uptake was recorded from Zn
0
treatment. In case of molybdenum
treatment, plant height, number of leaf, number of flower cluster, number of
flower, number of fruit, single fruit weight, vitamin content and yield increased
significantly with increasing Mo level upto 1.0 kg Mo/ha (Mo
1 .0
) where as
vitamin-A content increased significantly up to 1.5 kg Mo/ha (Mo
15). The
maximum plant height (62.70 cm), fruit number (42.49), vitamin-C content (16.24
mg/bOg) and yield (41.46 tlha) were recorded from Mo
10
treatment. The
maximum vitamin-A content with M
1.5
was (6047.0 j.tg/lOOg). The combined
effect of Zn and Mo showed that the combination ofZn
6M1•0
as 6 kg Zn/ha+1 .0 kg
Mo/ha gave the highest yield (4706 tlha) and vitamin-C content (18.60 mg/bOg)
while the highest vitamin-A content was obtained from the combination Zn
6Mo 5.
