Abstract:
An experiment was conducted at vegetable research farm of Horticulture
Research Centre, Bangladesh Agricultural Research Institute, Gazipur in the year
2019 to assess the resistance level of rootstocks against Bacterial wilt and to
evaluate grafting compatibility, seedling survivability, plant stand, growth,
development, and yield at field condition for summer tomato production. Six wild
rootstocks were taken to study the resistance against Bacterial wilt and most
yielding rootstock respectively and BARI hybrid Tomato-8 was grafted on to six
rootstocks having practiced with Integrated Pest Management approaches for
evaluating field performance. The experiment consisted of following seven
treatments, T
1
= WSS02 (Tomato grafted onto S. sisymbriifolium) T
2
= WSM05
(Tomato grafted onto S. torvum) T
3
ii
= WSM06 (Tomato grafted onto khag-1) T
4
=
WSM07 (Tomato grafted onto Khag-2) T
5
= WSM08 (Tomato grafted onto Khag
3)
T
6
= WSM04 (Tomato grafted onto EG 203) T
0
= BARI Hybrid tomato-8
(Control). Two rootstocks were showed resistant against Bacterial wilt and yield
showed better than control as well as any other treatments. T
1
(WSS02-S.
sysimbriifolium) & T2(WSM05 S. torvum) found to be the best where higher yield
was obtained from the treatment T2(WSM05 S. torvum) (34 ton/h) and
T
1
(WSS02-S. sysimbriifolium) (29 ton/h). Therefore, tomato may be grafted onto
S. torvum for higher yield & least wilt infestation. Thus, it may be suggested for
better yield and safe tomato production in the wilt prone areas of Bangladesh
during summer.
