Abstract:
This study was conducted to evaluate the efficiency of a liquid bio fertilizer (using goat
manure, fish manure, banana peels, Gliricidia, ash, soil and water) on growth
parameters of chili plant (Capsicum annum). The experiment was carried out during
March 2024 to June2024 at the Green Lanka Breeding center, Padukka. The study was
designed with six treatments and for each treatment four replicates. Treatments are T1
- I0% of organic fertilizer, T2 - 30% of organic fertilizer, T3 - 50% of organic
fertilizer,T4 - 100% of organic ferlrlizer, T5 - Control (without adding any fertilizer),
T6 - Recommended inorganic fertilizer. All the agronomic practices were followed
based on the recommendations. Plant height, Number of leaves per plant, Length of the
leaf per plant, Number of branches, Number of pods were measured once a week after
the fertilizer application. Analysis of Variance was performed to determine significant
difference among treatments (p< 0.05).
Results showed that the measured parameters showed variations among the treatments
but they were not significantly differed (p> 0.05). Therefore all the treatment levels
were same as there is no significant difference. But the average plant height is higher
in T2 where 30o/o of organic fertilizer used while the T4 has the lowest. Number of
leaves per plant was higher in T3 while the lowest was obtained in T5. The mean length
of the leafper plant was higher in T2 while the lowest was shown inT4. T3 was shown
the highest number of branches while T5 showed the lowest nurnber of branches. The
mean number of pods were high in T3 whereas Tl and T5 both were shown as lowest
values.
Among all treatments, T2 and T3 consistently perform the best across multiple
parameters including plant height, number of leaves, leaf length, number of branches,
and number of pods. All the treatments are the most effective in promoting plant growth
and development because there is no significant different.
