RATIONALE
is a unique specie cultivated for its
leaves, seeds, stems and calyces
Annual or perennial herb, woody-based
shrubs, growing to 2-2.5 m (7-8 ft)
Flowers with white to pale yellow; 8-10
cm in diameter
takes 6-8 months to mature(depends on
climate)
grown for home consumption, beverages
and pharmaceutical manufacturers
has a coloring agent that can replace
synthetic products
Roselle (Hibiscus sabdariffa, L.)
USES
1. LEAVES
for food (cury)
steamed along with lentils
and cooked, salad
used to add sourness to
chicken dish “Tinola”
tea
2. RED CALYCES
food coloring
syrups, jams
Different kinds of drinks
4. PLANTS
• cultivated for the
production of fibre
(from the stem)
• contain
antihypertensives
properties (treat
hypertension)
• mild laxative (used to
induce bowel
movements)
• diuretic (elevate the
rate of urination to treat
overdose or poisoning
Nutritional Value (per 100 g)
• Vitamin A - 2%
• Vitamin B2, Riboflavin
• Vitamin B3, Niacin
• Vitamin C - 14%
• Protein - 0.96g
• Calcium - 22%
• Iron - 11%
• Magnesium -14%
• Phosphoros - 4%
• Potassium -4%
• Sodium -6 mg
• Natural fats -0.64g
• Carbohydrates -11.31g
• Energy -205 kJ
At present
Roselle is attracting the attention of food and
beverage manufacturers and pharmaceutical
Seeds excellent feed for chickens
Stalk residue for cattle feed
Young flower buds can be dried and used for
tea and fresh used to make sinigang
Flower buds with calyx used to make juice and
wine
reports and studies on Roselle in the country,
esp. in Region 10 are inadequate , hence this
study will investigate its production, utilization
and commercialization in Northern Mindanao
General objectives
Development of Production, Post Production and
Utilization Technologies of Roselle in Region 10 which:
- create impact increasing productivity and
income of farming communities
- Potential products developed for export will
boost the economy
- utilization of Roselle products will provide
cheap source of basic nutrition among
Filipinos
Strategies of ImplementationMajor components
1. Production of Roselle package of
technology; cultural management (spacing &
fertilization) and intercropping
2. Development of harvest, post harvest &
value adding technologies; improvement of
quality packaging, labeling of developed
products
3. Determination of antioxidants, health and
wellness components of developed products
4. Product promotion, market linkaging and
commercialization
5. Monitoring and Evaluation
6. Project Management
Component 1.
Development of Production Practices
for Roselle-based Farming Systems
Technology
(3 studies)
Study 1. Influence of Organic and Inorganic
Fertilizer Application for Roselle Commercial
Production
Specific objectives
1. to determine the agronomic, yield and quality
performance of Roselle as affected by the
different rates of vermicast organic fertilizer
and inorganic fertilizer;
2. to optimize the rates of vermicast organic
fertilizer and inorganic fertilizers for
commercial Roselle production and
3. to determine the cost and return analysis of
the optimize rate of granulated nutrient
sources.
Highlights conducted in a 1,000 sq.meter
area using a split-plot design
arranged in RCBD and replicated 3
times.
treatments:
- Main-plots (rates organic
fertilizer, t/ha)
- Sub-plots (rates of inorganic
fertilizer, t/ha)
Seeds planted 1st Quarter of the
year 2015
Application
of treatments:
- Organic fertilizer (2
weeks before planting)
- inorganic fertilizers
(applied in 3 splits: basal,
30DAP and 5 days before
flowering
Data gathering (conducted
weekly)
Care & maintenance of
plants (watering, weeding)
CURRENT STATUS
- 1st Flower appearance
(5 months after
planting)
- 20% of the plants flowered
(to date)
Problems encountered
1. Due to long dry spell, early flower initiation was
observed at 3 months old
(supposedly flowering occurs at 4 ½ months after
planting at NMACLRC, Dalwangan, Malaybalay
Bukidnon condition)
2. Due to sudden change of climate (dry-rainy), it was
observed that plants at 5 months old re-grow or back to
vegetative stage resulting to late maturity
stop flowering initiation, fruiting stage and developed
more stems and increased in height
Study 2. Establishment of Appropriate
Planting Distance for Commercial Roselle
Production
Specific objectives
1. to determine the agronomic, yield
and quality performance of
Roselle as affected by the different
planting distance.
2. to identify the optimum
economical distance of planting
3. To determine the cost and return
analysis of the different planting
distance of Roselle for commercial
production
field is ready for lay-outing
(establishment)
delayed planting due to eratic
condition (no enough rains)
Insights
treatments:
- Main-plots (row spacing)
• MP1 – 60 cm bet. rows
• MP2 – 90 cm
• MP3 - 120 cm
• MP4 - 150 cm
- Sub-plots (plant spacing)
• S1 – 50 cm bet. Hills
• S2 – 75 cm
• S3 – 100 cm
• S4 – 150 cm
Study 3. Performance of Roselle Production
in Plantation-Based Cropping System
Specific objectives
1. to evaluate the agronomic, yield and
quality performance of Roselle as affected
by the different plantation-based
production systems;
2. to identify and recommend productive and
economical Plantation-based Cropping
systems for Roselle;
3. To determine the cost and return analysis
of the different plantation-based cropping
system
Insights
To be conducted in the station and identified sites
experiment using a RCB and replicated 3 times
Treatments:
- T1 – Roselle in Coffee-based cropping system
- T2 - Roselle in Cacao-based cropping system
- T3 - Roselle in Coconut-based cropping system
