Abstract:
This investigation was carried out at Mahasarakham University
Experimental Farm, Mahasarakham University, Northeast Thailand in the
late rainy season of the 2003 to 2004 with the use of Roi-Et soil series
(Oxic Paleustults). The experiment aims to search for more information
on the effect of different rates of chemical Paclobutrazol (PBZ) application
on growth, yield and quality of edible okra pods. A Randomised Complete
Block Design (RCDB) with four replications was used for the experiment.
The experiments consisted of five treatments, i.e., 0 (T1),
4,000 (T2), 8,000 (T3), 12,000 (T4) and
16,000 ppm ha-1 (T5) of chemical PBZ. The results
showed that an increase in PBZ application rate highly decreased plant
height, harvesting age and significantly decreased leaf area of the fifth
leaf but highly increased pod length, fresh weight/pod and fresh pod yield
ha-1 of the okra plants. PBZ had no significant effect on stem
diameter and diameter of pods of the okra plants. Total soluble solid,
fibre content, titratable acid, vitamin C and pectin contents in pods
were not affected by chemical PBZ application. Pod yield highly increased
with an increase in rate of PBZ application. The highest edible pod yield
reached a value of 4,501 kg ha-1 for the highest rate of PBZ
application (T5).
