ABSTRACT
Cabbage or pechay (brassica rapa) is the most demanded vegetable for
bulalo. In hydroponics, cost of production is very expensive because of the higher
cost incurred from Commercial Nutrient Solution (CNS). Thus, this study employed
an alternative for CNS which is organic nutrient solution with the additives of coco-
water and was conducted to determine the influence of coco-water , type of nutrient
solution and its interaction effect on the growth and yield of pechay or Chinese
cabbage and to determine the economic analysis coco-water as an additive. The
experiment was laid-out by using plastic bottles and other methods.
The addition of coco-water had significantly increased the length and diameter
of leaves; plant height; length of leaves; number of leaves and yield relative to
without coco-water addition. The types of hydroponic solution had influenced all the
growth and yield parameters in which CNS had predominantly increased the
number, length and diameter of leaves; plant height; length of leaves; number of
leaves and yield of pechay relative to FPJ extracts and coco-water alone application.
INTRODUCTION
Cabbage or Pechay (Brassica rapa), is a green, leafy vegetable often used in
Chinese cuisine. The vegetable is related to the Western cabbage, and is of the
same species as the common turnip. Chinese cabbage is believed to have
originated in China. Later, it was likely introduced to other countries throughout the
region and then spread around the world. Today, Chinese cabbage is available in
many countries but tends to be most popular in Asia.
In the Philippines, it is popularly known as Pechay or Petsay. It was one of
most often used vegetable in many Filipino dishes. Petsay is added to Filipino stews
such as nilagang baka (boiled beef) or bulalo (boiled beef shank). People who
choose to eat it raw can enjoy it tossed in a salad mixed with other greens. Those
can be overcome through hydroponics system of production under protected
structure. Hydroponics system is one of the important technologies that can be
occupied in limited space with less amount of soil.
Furthermore, hydroponic system was popularly used to come up with an off-
season production during the onset of wet seasons.
However, an alternative, affordable, and safest way to provide nutrients
solution in hydroponics is the utilization of organic nutrients solution from fermented
plant juice extracts such as kangkong and kamote tops which is relatively high
in beta-carotene, natural antioxidants, protein, carbohydrates, and dietary fibers and
also tomatoes are a rich source of lycopene, lutein, and beta-carotene.
In addition of coco-water, the influence of K in coco-water was reported by
Roldan [1] in pechay in which exchangeable K in soil is greater than the commercial
liquid fertilizer. Moreover, Founder [2] found out that coco water has higher
cytokine’s which regulates in maintaining greenness of leaves and encourages cell
division of plants towards its growth and development.
Therefore, to come up with greater uphold of available nutrients and to
stabilize acidity of FPJ formulated nutrient extracts solution, it can be recovered by
adding coco-water as mixture additives component. However, the influence of coco-
water as an additive for nutrient solution in hydroponic system was still under
verification. To come up with a protocol on the effectiveness of coco-water on the
growth and yield of pechay. Hence, this study was ascertained.
RESEARCH OBJECTIVES:
The study aimed to determine the influence of coco water as an additive; to
determine influence of different types of nutrient solution, and their interaction effect
influencing the growth and yield of pechay using coco-water as additives for
hydroponics system.

Influencing the Growth and yield of Pitchay under Hydroponics. This research aids to
reinforce individuals about the goodness of organic farming in Hydroponics system.
COMMUNITY. This study may help the member of the community to get
substantial information about the goodness of usage of concoction. It may develop
the sense that people already know what are the benefits of having an Organic
Farming which is the way of Hydroponics system.
RESEARCHER. This study may help the researcher to determine the
revolution of organic farming, which recognize in spite of spouting various methods
of producing crops.
STUDENTS/TRAINERS. Through the help of this study trainers may know the
value of organic farming in everyday living.
FUTURE RESEARCH. This study may help to provide ideas to the future
research on how to attain good production through the usage of Coco Water on
Fermented plant juice extract, Influencing the Growth and yield of Pitchay under
Hydroponics. However, this may become also the reference and guide of the future
research to investigate the essentiality of organic farming system.
MATERIALS AND METHOD
Treatments and Experimental Design
The following treatments were evaluated:
A. Main plot. Additives nutrient solution application
1 - without coco water
2 - with coco water
3 – with coco water and FPJ
Hydroponic Structure Installation
Coco lumber and bamboo were used as frame materials
Container Preparation
I used plastic containers.
Seedling production
Seeds of lettuce were sown in seed boxes filled with mixture of garden soil,
compost and carbonized rice hull at 1:1:1 ratio. The seedlings were pricked 7 days
after sowing in to the seedling tray. The seedling was hardened by gradual exposure
to sunlight and regular water withdrawal for 7 days.
Preparation of Fermented Plant Juice (FPJ)
1/2kg. Of Kangkong were chopped into tiny pieces and thereafter placed
separately in a plastic pail. It was mixed separately in a 1/2kg of brown sugar and
was poured by the same quantity of water following the 1:1:1 ratio. Fermented plant
juice was tightly covered with craft paper and then placed in a cooler dry place.
Thereafter, it was fermented for 7 days until sweet/alcoholic odor appeared. The
fermented kangkong and kamote tops were strained by using an ordinary strainer.
The extracted plant juice was placed in a plastic container and directly stored in a
cool and dry place prior to application.
Application of the different FPJ extracts solution
Different FPJ extracts at 1cup volume was diluted in 2L of water. Inorganic
nutrient solution as formulated by Salas et al. [3] was used in the study. In treatment,
coco-water alone was applied. Every twice a week application of FPJ and coco water
extract.
Care and Management
Watering was done twice a day (early in the morning and late in the
afternoon). Manual weeding was done as soon as the weeds appeared. Insects was
controlled by hand picking.
Data Gathered
1. Number of leaves. This was done by counting the leaves produced by pechay
towards its growing period.
2. Length of leaves. This was obtained by getting the length of from the tip of the leaf
and at the base of the leaf.
3. Diameter of leaves. This was measured by getting the three broader leaves of
pechay.
4. Plant height. This was done by measuring the initial height one week after
transplanting and final height during harvest from the ground level up to the tip of the
terminal end of the main stem using a ruler.
5. Length of roots (cm). This was obtained by measuring the longest roots of the
pechay at harvest.

Horticultural Characteristics of Foliage Growth of pechay
The length and diameter and plant height were significantly influenced by
coco-water and FPJ application. The application of coco-water (2&3) had longer and
broader leaves with much taller pechay plant relative to without application of coco-
water (1) 25 days after planting.
This was reported by Roldan [4] on pechay in which application of formulated
liquid fertilizer from coco-water nutrient solution had significantly increased its plant
height.
The positive effect of coco-water as additives could possibly attributed by the
presence of undefined nutrients as well as growth hormones and vitamins needed
for cell development. However, no significant effect was observed in the number of
leaves parameter.
Regardless of additives nutrient application, types of nutrient solution had
significantly influenced the number, length and diameter of leaves, and plant height
of pechay 25 days after planting.
Yield
The yield of pechay was significantly influenced by the additives nutrient
solution application. Coco-water (2) had significantly higher yield as compared to
without coco-water application (1). Regardless of additive nutrient solution, the yield
of lettuce was significantly affected by the type and combination of nutrient solution.
Meanwhile, in terms of types of nutrient solution, addition of coco-water had
significantly higher yield than without coco-water.
RECOMMENDATION
Coco-water as an additive for nutrients solution of hydroponics system is
highly recommended for pechay production. The use of coco-water in hydroponics
system should be further studied in other crops such as fruit vegetables by
increasing its volume of application.
