Abstract:
ABSTRACT
The study was carried out in the Horticulture farm and laboratories of Sher-eBangla
Agricultural University, Dhaka, Bangladesh during the period from
November 2012 to February 2013 to study Physio-morphological response of
Capsicum annum to water stress and exogenous application of pyrabactin. The
experiment consisted of seven treatments, viz., T
1
= 100% optimum water, T
2
=
50% of Optimum water, T
3
= 50% of Optimum water + pyrabactin 50ppm, T
4
=
50% of Optimum water + pyrabactin 100ppm, T
5
= 25% of Optimum water, T
6
=
25% of Optimum water + pyrabactin 50ppm, T
7
= 25% of Optimum water +
pyrabactin 100ppm. The experiment was laid out in Completely Randomized
Design (CRD) with three replications. Among the six treatments of water stress
condition except the optimum water condition, results showed that the maximum
plant height, number of branch per plant, fresh weight per plant, TDM, number of
fruit per plant, fruit length, fruit diameter, indi vidual fruit weight was recorded in
T
4
treatment. The maximum yield of fruits per plant (728.3 g) was also recorded
from T
4
treatment which was close to the yield of fruit (952.1 g) recorded in T
1
.
Comparing with other water stress condition T4 gave the best result and
application of pyrabactin minimized water stress affect. So pyrabactin may be use
in cultivation to minimize yield reduction in drought condition.
