Botanical Observation
The observation was recorded on 30, 60 and 90 DAS.
Five randomly selected plants were tagged for
observations in each treatment of irrigation plots.
Germination Percentage
Number of seeds germinated in each plot was counted
on the fourth and fifth day after sowing and was
expressed in percentage. The different types of
irrigation had significant effect on germination
percentage of
bhendi
at 5 DAS. The highest
percentage of germination (98%) was recorded in sub
surface irrigation plot and lowest percentage (87%)
was recorded in surface irrigation plot at 5 DAS. The
application treatments of different type of irrigation
had significant effect of
bhendi
. Among the treatments,
sub surface irrigation plot registered the highest
percentage of germination (90%), while recorded the
lowest (90%) at 5 DAS.
Plant Height
The height of plant was measured from the bottom of
the plant to the tip of the longest leaf by using a scale
on 30, 60 and 90 DAS in five plants at each stage of
the crop growth and the average value was calculated
and expressed in cm. The different types of irrigation
had a significant effect on plant height of
bhendi
at 30,
60 and 90 DAS. The highest (21.55 cm) plant height
was recorded in sub surface irrigation plot and the
lowest (15.95 cm) was recorded in surface irrigation
plot at 30 DAS, while at 60 DAS, the tallest plant
(120.25 cm) was found in sub surface irrigation and
shortest plant height (108.08 cm) was recorded in the
surface irrigation plot. The highest plant height
(180.05) was recorded in sub surface irrigation and
followed by in drip irrigation (175.0 cm), micro
sprinkler irrigation (172.08) and surface irrigation
(160.5 cm) at 90 DAS.
Number of Leaves
The total number of leaves was counted in each of the
five selected plants on 30, 60 and 90 DAS and the
average value was expressed in number per plant. The
application of fertilizer had significant effect on
number of leaves per plant in
bhendi
at 30, 60 and 90
DAS. More number of leaves (14) per plant was
recorded in sub surface plot and followed by drip
irrigation (10) and the lowest number of leaves (8)
was recorded in surface irrigation on 30 DAS, while at
60 DAS, more number of leaves per plant (34) was
recorded in sub surface irrigation plot and less in
surface irrigation plot (28).
Number of Branches
The total number of branches was counted in each five
selected plant on 30, 60 and 90 DAS and the average
value was expressed in number per plant. In case of
fertilizer application through fertigation of had
significant effect of branches of
bhendi.
In case micro
sprinkler, the fertigation is similar to foliar sprays.
More number of branches (12) was recorded in the
treatment of sub surface irrigation plot, the treatment
of drip irrigation plot (10) and treatment of micro
sprinkler irrigation plot (8) was recorded in harvest
stage of the crop.
Number of Flowers
The total number of flowers was counted in each five
selected plant on 30, 60 and 90 DAS and the average
value was expressed in number per plant. Application
fertilizer through fertigation had effect on number of
flowers in
bhendi
. The more number of flowers was
recorded in the treatment of sub surface irrigation (66)
and the lowest number of flowers in treatment of
surface irrigation plot (40).
Number of Fruits
The total number of fruits was counted in each five
selected plant on 30, 60 and 90 DAS and the average
value was expressed in number per plant. In case of
fertilizer application through fertigation of had
significant effect of fruit of
bhendi
. In case micro
sprinkler, the fertigation is similar to foliar sprays.
More number of fruits (62) was recorded in treatment
of sub surface irrigation plot, followed by the
treatment of drip irrigation plot (56) and lowest
number of fruit (32) was recorded in treatment of
surface irrigation plot.
Fruit Yield ha
-1
Total fruit yield per ha was recorded and the average
value was expressed in t/ha. Among the treatments,
the highest production (25.24t/ha) was recorded in sub
surface irrigation plot, followed by drip irrigation plot
(22.40t/ha) and micro sprinkler irrigation plot
(16.80t/ha). Among the treatment of different
irrigation plots, the lowest production (14.5t/ha) was
recorded in surface irrigation plot.
3 Conclusion
A field experiment was conducted at Agricultural
college and research institute, Madurai, India to study
