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”, fruit plant’, weight tomato”, yield plant’, yield plot”
and yield hectare’ 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. JAA 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.
Description
Vegetable is the most important component of a balanced human diet and act as a
nutritive food. Among the vegetables tomato (Lycopersicon esculentum Mill.) is
very important and widely grown not only in Bangladesh but also in many
countries of the world for its taste and nutritional status. Tomato is considered to
be a day neutral plant but it is not productive under high temperature (> 30° C) due
to thermo-sensitiveness for flowering (Mondal et a/. 2011). In Bangladesh,
congenial atmosphere remains for tomato production during November to March.
So, tomato is widely grown in Bangladesh usually in winter season. Plant growth
regulators are one of the important factors for yield.
