2. INTRODUCTION
Ampalaya or bitter gourd, which is known in the Philippines as
ampalaya, is an annual plant that is native in this country. It is botanically
known as (Momordica Charantia Linn) is one of the most important commercial
and backyard fruit vegetables in the country today. It has both nutritive and
medicinal use. The fruit and leaves of which are used as vegetable and the
latter are further used as a laxative for new born babies while the stem and
roots as antidotes for fever. They are rich in calcium, phosphorus, iron,
carbohydrates and vitamin B. It is also known to cure diabetes, arthritis,
rheumatism, asthma, warts, and ulcer.

Several supplements for diabetics have been developed using the
ampalaya, most notably an ampalaya tea and capsules using the dried
ampalaya fruit. As diabetes continues to rapidly spread across countries and
social strata, the ampalaya is expected to provide diabetics with a safe and
natural alternative to help control their elevated sugar levels. While the herb is
still rare in countries where it is not indigenous, expect the Ampalaya and
Ampalaya-based products to start gracing local grocery shelves as more and
more people realize its potential anti-diabetes use. Ampalaya can be direct
seeded or transplanted. Direct seeding is most common, a hectare of
3. production area requires 2.5 to 3.0 kilograms of seeds, Seeds are soak in water
overnight or wrap in cheesecloth to facilitate water absorption. Seeds are
planted the following day or as the radicle break. (http://Ezine
Articles.com/347711).
Transplanting can also be done especially when the seeds are scarce and
during off-season planting. Seeds are planted in small plastic bags (1 seed/bag
with soil mixture of 1:1 garden soil and sand/compost/carbonized rice hull)
and transplanted to the field when the vine starts to grow. Pre- germinated
seeds result in good seedling and an even crop establishment. Early planting in
some areas is usually done during the months of October to December and late
planting during the month of January to February.
The rate and distance of planting use by most farmers is 3 meters
between furrows and 0.5 meters between hills with 3 seeds. Other
recommended spacing is: 30 m x 30 m with 1 plant/hill and 2.0 m x 0.5 m
with 2 plants/hill. http://technokits.blogspot.com/2008/11/ampalya-

6. REVIEW OF LITERATURE
According to Jamon, bitter gourd (Momordica charantia) which is
sometimes called “Bitter melon” or “Balsam Pear” is a locally known ampalaya.
It is a vine that climbs on trellis or creeps on the ground. It belongs to the
family of cucurbits or cucurbitaceae. Bitter gourd (Ampalaya) is one of the
leading commercial fruit vegetables in the country. It ranks second to the
squash in total hectorage among the cucurbits. Based on analysis concluded
by Food and Nutrition Research Institute (FNRI) (1980), fruits and shoots have
high leads of vitamin A, B, C and calcium, phosphorous and iron. Ampalaya
also has medicinal value. The leaves and leaf buds of the ampalaya or parya
are crushed and moistened with coconut oil. The crushed moistened leaves are
wrapped with clean cloth is the form of a nipple to be sucked by new-born
babies. The folk believe that the juice hardens the bones of the babies.
Ampalaya leaves and fruits are excellent sources of iron, calcium, phosphorous
and Vitamin B. These elements are components of Biochemical compounds
essential. In teeth and bone formation and ossification, this native practice is
encouraged but care should be taken in its preparation. The leaves should be
washed thoroughly and the cloth used for wrapping the pounded leaves should
be clean and free from germs. The juice of ampalaya leaves is also used to expel
meconium and the ripe seeds can be used as decoration taken in large
quantities for a number of days as abortive agent and checks urethral
7. discharge. The tops, leaves and fruits are usually eaten in raw or cooked form.
The fruit can be fried with eggs and served for breakfast. It is usually used as
one of the mixtures in the known Ilokano dish or recipes known as “Pinakbet”.
In eateries and restaurants, they are prepared or cooked with pork, beef or fish
and saved as a special menu for customers. Aside from being used for human
consumption, the leaves are also good for the treatment of skin diseases. Like
ringworm and Tina Flara. Medical laboratories also utilize the sap in the
preparation of medicines for stomachache.
According to Oshima, the staff writer of “Taking the bitter with the
sweet”, that for a long time, however, farmers on the mainland Japan grew it
only to shade their gardens from the sun, and its usage as a foodstuff was
limited to southern Kyushu and Okinawa, where the hot summer weather
caused a lack of other locally grown green vegetables.Today, as tourism to
Okinawa introduces travellers to famous local dishes such as goya champuru
(stir- fry of bitter gourd with tofu, egg and other ingredients), more and more
people are becoming accustomed to the vegetable. The gourd’s popularity has
also been accderated by the well- publicized facts about its nutritional value.
One hundred grams of bitter gourd contains 120 mg of vitamin C much higher
than many vitamin C rich vegetables and fruits.Scientific data has shown this
extremely rich vitamin content is not lost with heating. Okinawa is now the
largest bitter-gourd producing district in Japan. Production has more than
doubled from 2,700 tons in 1990, to 6,000 tons in 1997, most of which is
8. shipped to the mainland. The vegetable’s best season is June to August the
bitter flavour increases as its nutritional levels peak.
According to Yaedake, the staff writer of “Taking the bitter with sweet” in the
Japan. Times online, in an attempt to jump on the bandwagon, Okinawan
companies have put various bitter- gourd products on supermarket shelves,
including goya sherbet, goya juice and dried goya. Goya tea made by drying
and roasting sliced bitter- gourd picked in its peak season, is also popular. To
prepare bitter- gourd for cooking, cut the vegetable in half lengthwise, discard
the seeds and fibrous core, and then slice into half- moons. Do not remove the
skin. A dash of salt tames the bitterness.
According to medicalhealthguide.com, the Philippine Department of
Health endorses the ampalaya plant for use as an alternative medicine for
many conditions. Ampalaya is recommended to help relieve liver problems, to
control blood sugar, HIV, skin diseases, sterility in women, to kill parasites, to
reduce fever and purge illness from the body through defecation. Both the
Ampalaya leaves and fruits contain vitamin B, iron, calcium, beta carotene and
phosphorus. Some of its benefits are, it disinfects, relieve cold symptoms,
boosts immunity, regulates blood sugar levels, lowers blood pressure, relieves
headaches and protects spleen and liver.
9. MATERIAL AND METHODS

The different treatments to be used in the study are as follows:
10. Factor A – Ampalaya Varieties
V0 - BonitoF1
V1- Jade star F1
V2- Galaxy F1
V3- Galactica F1
Planting
The varieties of ampalaya seeds will be transplanting can also be done
especially when the seeds are scarce and during off-season planting. The
ampalaya can be direct seeded or transplanted. Direct seeding is most
common, a hectare of production area requires 2.5 to 3.0 kilograms of seeds,
Seeds are soak in water overnight or wrap in cheesecloth to facilitate water
absorption. Seeds are planted the following day or as the radicle break.
Land Preparation
The field should be well prepared, plowed and harrowed twice to remove
weeds and other plant debris in the field. Furrows are then made 3 meter
apart.
Rate of Planting
The rate and distance of planting use by most farmers is three meters
between furrows and 0.5 meters between hills with 3 seeds line at 4 inches
apart. Other recommended spacing are: 30 m x 30 m with 1 plant/hill and 2.0
m x 0.5 m with 2 plants/hill.
11. Harvesting
Harvest when the fruits are green. Harvesting will be starts 45 to 50 days
after seedling. It can be done twice a week. Harvest early in the morning to
protect harvested fruits against rain, sun, and mechanical damage.
Care and Maintenance
Water and Weeding Management of Ampalaya requires an abundant
supply of moisture for vegetative and reproductive development to maintain a
good crop stand in the dry season.
Data to be Gathered:
A.Cash Crop (Ampalaya)
a) Numbers of days to seed emerge. This will be determined by counting the
numbers of days from sowing to approximately 50% of the seedling have
emerged.
b) Number of days to flowering. This will be done by counting the number of
days from seed emergence to approximately 50% of the plants have
developed flowers.
c) Number of harvested fruits per hill. This will be determined the counting
the number of harvested fruits per hill in every harvesting.
d) Weight of harvested fruits per hill, plot and ha (kg).The weight of
harvested fruits will be recorded by weighing the harvested fruits per hill
plot and ha using electronic weighing balance express in kilograms.
12. e) Gross income (Php). This will be taken by computing the total yield of
ampalaya per hectare to the current price of the crop. Price will be based on
the price in the market.
f) Total expenses (Php).This will be taken from the actual expenses incurred
in growing ampalaya.
g) Net income (Php). This will be computed by subtracting the total expense
of raising ampalaya from the gross income.
h) Return on investment (%). This will be computed by dividing the net
income by the total expenses multiplied by 100.
B. Growth of Perennial crops
Monthly height. Height of rambutan will be gathered by measuring the plants
from the ground level to the apical tip with the use of a meter stick in meters.
Crown diameter. This will be gathered by measuring the diameter of the crown
with the use of a meter tape in centimeters.
Stem diameter. This will be gathered monthly by measuring the diameter of
the main stem at 35cm from the ground with the use of a vernier caliper.
Additional number of leaves. Additional number of leaves will be gathered by
counting the number of leaves produced in monthly basis.
Additional number of branches. Number of branches will be gathered by
counting the number of branches produced in monthly basis.
Final height. Height of rambutan will be gathered by measuring the plants
from the ground level to the apical tip with the use of a meter stick.
13. C. Soil Properties before and at the termination of the study
The soil sample before planting and after harvesting will be collected and
subjected to analysis at the bureau of soils, to analyze the soil pH nitrogen;
phosphorus and potassium. Crops grow well in any types of soil with a pH
of 5.5-6.5. Higher yield will be attained on sandy loam soil. Soil analysis will
be must for commercial planting.
D. Climatological Data
1. Rainfall. This will be taken at the weather station of the college using the
rain gauge instrument.
2. Temperature. This will be taken at the weather station of the college
using thermometer.
3. Relative Humidity. This will be taken at the weather station of the
college using the barometer.
4. Light intensity. This will be collected at 10 am and 2 pm at the start
and end of the day using the luxmeter.
All the data gathered will be summarized, presented and analyzed using
the analysis of variance (ANOVA) in 4x4x3 factorial in Randomized Complete
Block Design (RCBD). Duncan’s Multiple Range Test (DMRT) will be used in
the comparison among treatment means.
