| dc.description.abstract | The experiment was conducted at research field and laboratory of the Department of
Crop Physiology and Ecology, Hajee Mohammad Danesh Science and Technology
University (HSTU), Dinajpur during the period of December 2017 to April 2018. The
experiment was laid out in randomized complete block design with three replications.
Each replication then divided into six unite plot of 2.0 m 1.5 m sizes. The distance
between block to block was 1m and plot to plot was 0.5 m. The experiment comprised
of two factors- A: Two concentrations level of GA (Control and 300 ppm) B: Four
tomato varieties- (Moharaza, Konok, Bipul Plus and BARI tomato 4). Plant height,
number of leaves per plant, number of branches, days required for first flowering
initiation, days required for 50% flowering initiation, days required for fruit setting,
fruits cluster plant-1, fruits cluster-1, fruits plant-1, length of fruit, diameter of fruit,
weight tomato-1, yield plant-1, yield plot-1 and yield ha-1 were significantly influenced
by the combined application of GA and varieties of tomato. BARI tomato 4 attained
the highest fruit yield with 300 ppm GA and lowest yield was observed in Konok at
control condition. GA treated plots showed better performance for growth parameters
and yield compared to control condition. Therefore, 300 ppm GA was more suitable
for tomato cultivation compared to control condition. Among the treatment
combination, BARI tomato 4 with 300 ppm GA was superior from others tomato
varieties (Bipul plus, Moharaza and Konok) and Konok was inferior from others
tomato varieties (BARI tomato 4, Moharaza and Bipul plus). GA treated plots of
Moharaza and Bipul plus was showed the intermediate results for yield and yield
attributing characteristics. | en_US |
