| Abstract: |
A study was conducted at Rampur, Chitwan from April 2 to June 20, 2003 in a split plot
design with three replication by using two commercial okra cultivars Arka Anamika and
Parvani Krallli and four growth regulators. The growth regulators Gibberellic acid (GA3)
(50 ppm), 2,4-D (5 ppm), Ethrel (200 ppm) and Triacontanol (0.5 ml/lt) and simfJie water as
control were used for 24 hr seed soaking (except Ethrel) and as spray of all growth
regulators at 30 day after sowing (DAS) and second spray of Triacontanol at 45 DAS. The
effect of GA3 on seed germination was found 24.5% higher than the control. The effect of
Triacontanol on plant height (191.3 em) was significantly higher than control (140.2 em).
The same growth regulator showed loll'est node to flowering (3.2) and days to 50% flowering
(4/days) and these were four nodes and 44 days in the case of control. The highest number of
fruits/ plant (24.9) and the highest productivity (29.98 tlha) were observed from Triacontanol
and these were 16./% and 16.72% more titan control treatment respectivel)' The effect of
two varieties and interaction among varieties and growtlt regulators for all above variables
were statistically non significant. The easiness of preparing Triacontanol solution simply by
mixing 0.5 ml of its commercial formulation per liter of tap water and its promising effect on
vegetative growth, reproductive behavior and yield attribute of the crop makes it a promising
growth regulator for okra growers as compared to otl1er growth regulators for early and
more production. Further research is suggested for confirmation as it is based on one
season. |
