Abstract
The study was conducted in the
central farm of Sher-e-Bangla Agricultural University (SAU),
Sher-e-Bangla Nagar, Dhaka during November to March, 2017 to screen
varietal performance of tomato against the infestation of white fly
and tomato fruit borer. Ten varieties of tomato e.g., BARI Tomato-2,
BARI Tomato-3, BARI Tomato-14, BARI Tomato-15, BARI Tomato-16,
BARI Tomato- 17, Sonali-35, Solar, Bijli-11 and Sonali-12 were
screened against these two insect pests and considered as treatments.
The field study was laid out in single factor Randomized Complete
Block Design (RCBD) with three replications. At 50 days after
transplantation (DAT) the maximum number of white fly plant-1 (27.97)
was recorded from Sonali-35 and the minimum number of white fly
plant-1 (19.23) was recorded from BARI Tomato-3. The highest number
of branches, leaves, inflorescence plant-1 was recorded in BARI
Tomato-3 plot and lowest was recorded in Sonali-35. The highest
percentage of branches, leaves, inflorescence infestation was
recorded in Sonali-35 and lowest was recorded in BARI Tomato-3. At 85
DAT the maximum number of fruit borer plant-1 (10.70) was recorded
from Sonali-35 variety and the minimum number of fruit borer plant-1
(9.06) was recorded from BARI Tomato-3. At 85 DAT the highest number
of infested fruit plant-1 (4.13) was recorded from BARI Tomato-16
variety and the lowest number of infested fruit plant-1 (3.12) was
recorded from BARI Tomato-3. Total number of fruit plant-1,
individual fruit weight, and weight of fruit plot-1 and yield of
different varieties varied significantly due to infestation and
performance of variety. The highest yield (53.83 t ha-1) was obtained
from BARI Tomato- 3 variety and the lowest yield (47.01 t ha-1) was
obtained from BARI Tomato-15. All varieties were infested by white
fly and fruit borer but the BARI Tomato-3 variety was less damaged
among 10 tested varieties and considered to be more tolerant against
whitefly and fruit borer which resulted in higher yields as well.
Keywords: Tomato, white fly and fruit borer.
