Abstract:
This experiment was carried out to study develop an organic liquid soil enhancer using
organic waste materials from the agriculture animal and crop farms and to find the effect
of formulated fertilizer. [n this study, cow urine, cow dung and banana psudostem are
used to make NPK rich organic liquid fertilizer for applying on Okra (Abelmoschus
esculentus) cultivation. Okra (Abelmoschus esculentus) is annual herbaceous plant
belongs to the Malvaceae family. It known as "lady's finger," and is a flowering plant that
is native to Ethiopia but is now widely grown in tropical and subtropical regions around
the world. The experiment was laid on complete randomize design (CRD) with six
treatments and four replicate. The experiment location was department of botany
department polytunnel, Eastern University Sri Lanka. The liquid organic fertilizer was
prepared by using Banana Pseudostem extract with decomposed solution (cow dung+
cow urine).The treatments wereT1 (100% inorganic fertilizer),T2(100% liquid organic
fertilizer), T3 (50%inorganic fertilizer+ 50% Liquid organic fertilizer), T4 (25%
inorganic fertilizer + 75% organic fertilizer),T5 (75% inorganic fertilizer + 25% Liquid
organic fertilizer) and T6 (Soil only as control). Analysis of Variance was performed to
determine significant difference among treatments (p< 0.05). Plant provided with T1 and
T2 was better performance in growth parameters viz. Plant height, Leaf numbers, Leaf
area index, Leaf chlorophyll contents, and numbers of flowers and pods and, pod fresh
weight and Pod length. While the lowest growth parameters were observed in T6
(control). From this study it could be concluded that, T3 (50% inorganic fertilizer+ 50%
Liquid organic fertilizer) was the better fertilizer combination for the plant.
