| dc.description.abstract | The experiment was conducted at research field and laboratory
in the Department of Crop Physiology and Ecology, Hajee
Mohammad Danesh Science and Technology University,
Dinajpur during the period of December 2013 to April 2014. The
experiment was laid out in two factors randomized complete
block design with three replications including three
concentrations of Indole Acetic Acid (0, 100 and 200 ppm) and
three tomato varieties (BARI tomato 7, Manik and Ratan). Plant
height, number of leaves and number of branches, days required
for first flower initiation, days required for 50% flowering, days
required for fruit setting, fruit cluster plant-1, fruit plant-1,
weight tomato-1, yield plant-1, yield plot-1 and yield hectare-1 were
significant influenced by the combined application of IAA and
varieties of tomato. BARI Tomato-7 the highest fruit yield with
100 ppm IAA and the lowest yield was observed in Ratan with 0
ppm IAA. IAA treated plots showed better performance for
growth parameters and yield compared to control condition and 100 ppm IAA was more suitable than the 200 ppm IAA for
higher yield of tomato cultivation. Among the treatment
combinations, BARI Tomato-7 with 100 ppm IAA was superior,
Ratan with 0 ppm IAA was inferior and BARI Tomato-7 with 200
ppm IAA, Manik with 200 ppm IAA and Ratan with 200 ppm IAA
treated plots showed the intermediate results for yield and yield
attributing characteristics. | en_US |
