Palawan Research and Experiment Station


The station was acquired through the Presidential Proclamation NO. 463 of President Elpidio Quirino on December 23, 1953 with an area of 62 hectares. From 1953 to 1987, the station was named “Palawan Seed Farm” as it was intended for nursery and propagation site under the control and supervision of the Bureau of Plant Industry.

In 1991 the Palawan Seed Farm or Palawan Agricultural Experiment Station was renamed STIARC – Research Outreach Station for Hillyland Zone (Low Elevation) by virtue of Administrative Order NO. 6 and 19 series of 1991 issued by former Agriculture Secretary SENEN BACANI and Regional Special Order No. 122 series of 1991 by Director CONRADO I. GONZALES.

However, in 1990 and 1991, Puerto Princesa City Hall, Palawan Sport Complex and Palawan State University building were erected within the area of the Station, claiming 2/3 of the land area. At present, 20 hectares are being maintained by the station to implement its research and production projects. The main office is located in Sta. Monica, Puerto Princesa City, Palawan, Philippines headed by the Station Superintendent or Agricultural Center Chief III. The Station is part of Mindoro, Marinduque, Romblon, Palawan (MIMAROPA) or Region IV-B.


The Station response to the needs of the province of Palawan, especially in the field of Agricultural Research, Development and Extension corollary to the goals and objectives of AFMA.


STIARC-ROS for Hillyland Development Zone (Low Elevation) is responsible for strengthening the Provincial Research and Development (R&D) system in agriculture for effectiveness and efficiency and promote the province’s agricultural growth through R & D. Its efforts are focused on uplifting the quality of life of hillside, lowland small farmers and on sustainability of resource base over a longer term.


A. General

To implement local Research, Development and Extension corollary to Agriculture and Fisheries Modernization Act (AFMA).

B. Specific

1. To establish projects in coordination with other local research institutions and laboratory support facilities

2. To implement, review and monitor on-going research and development Projects in accordance with the Work and Financial Plan for the station;

3. To take part in the formulation, development and implementation of R, D & E plan for the Province

4. To support and strengthen a local R & D information network through collaboration with other agencies

Two Major Functions


DA-ROS-PAES is mandated to promote the province’s agricultural growth through research and development. Its efforts are focused on the upliftment of the quality of life of small farmers and on the sustainability of resource viability over a longer term.

Its vision is to have a progressive rural recovery with dynamic agro-industrial communities throughout the province, propelled by organized and self-reliant farmer entrepreneurs.

As a center for research and development in the province for the past many years, the station is the foundation of the cashew industry, owing to its culture of the premier varieties. With justifiable pride, it can boast as the prime source of several high yielding or promising cashew varieties/cultivars that abound in many cashew-growing places in the country today, which are products of research.

Hence, the R & D activities of DA-ROS-PAES have contributed tremendously to the upliftment of the kind of living conditions of the cashew farmers.

To provide/offer more significantly to its mandate and vision the station’s R & R widen its scope to several commodities that provide a better income to the farmers. And also developed close linkages with the extension services for organizing technology verification and demonstration trial particularly on the control of mango pulp weevil and farming system on farmer field condition, so that this on-farm trial/research should provide a feedback for the modification of new technology to make it more acceptable to farmers and to determine the economic viability under actual condition.


Production of high quality seeds, plant materials that will cater to the needs of farmers in the Province of Palawan is the ultimate goal of the station.

Specific Activities Undertaken:

1. Seed Production – Production of seed materials for rice and corn and assorted vegetables.

2. Plant Material Production – Management and Maintenance of Nursery. Maintenance and development of scion grove and orchard on plantation crop.

3. Soil Testing and Sampling – NPK analysis of soils.

4. Trichoderma Production – Production of compost

Two Major Programs


Formerly the home of Palawan Integrated Area Development project (PIADP) Phase I and Phase II. After the termination of both projects in 1998 it became the center of all activities of Agricultural Intensification and Diversification Program (AIDP).

The area is located 14 kms. from the city proper of Puerto Princesa and formerly part of Iwahig Prison and Penal Farm, through Presidential Proclamation signed by then President Ferdinand E. Marcos in 1979. In this proclamation, 500 hectares were segregated for the purpose of establishing agricultural research, training and extension facility of the Department of Agriculture, Regional Office No. 4.

In the implementation of the PIADP, 67 hectares was allotted out from 500 hectares for Agricultural Intensification and Diversification (AID), which was called crop component of the project and the rest of the area were given to Livestock component.

In the eastern part, the area is bounded by Puerto Princesa Bay Mount Beaufort in the west, Iwahig Prison and Penal Farm in south, and barangay proper of Irawan in the north. The topographical setting of the area is flat to slightly rolling and mountainous particularly in the western portion.

Aside from regular operation of AIDP in the center the project is also supporting the Palawan Soils Laboratory (PSL) and Seed Testing Laboratory. These facilities are considered regional facilities. In addition too, a Tissue Culture Laboratory is established jointly by AIDP and Palawan Tropical Forestry Protection Program (PTFPP). Equipments and some chemical were provided by the PTFPP while the building is provided by the DA. Budget in this year operation will be fully shouldered by AIDP.

a. Palawan Soils Laboratory (PSL) - A regional facility responsible forproduction of organic fertilizer and analysis of soil for proper fertilizer recommendation.

b. Tissue Culture Laboratory – The laboratory was established at theProvincial Agricultural Center (PAC) in Irawan, Puerto Princesa City last September 2002.

This is a Joint Project of the Department of Agriculture – Research Outreach Station and the Palawan Tropical Forestry Protection Programme (PTFPP). The PTFPP provided funds for the procurement of laboratory equipment and apparatuses. As counterpart, the Department of Agriculture was responsible for the renovation of the building, procurement of chemicals and laboratory supplies and training of two (2) staff involved in the operation. 

This project involves collection of stocks, plant, materials, preparations of stock culture, media culture and construction of green house. Tissue Culure is the most rapid method of multiplying plants for thousands or even millions of plants produced from a small tissue in a short time. This process consists growing plants as a bud in an artificial environment so that numerous plants can be produced from a single mother plant tissue.

It is at present gaining great importance as a tool to study various basic problems not only in the field of physiology, biology and genetics but also in forestry, horticulture, and agro-forestry.

In the Philippines, plant tissue culture is already popular. It is already being done in production of crops such as banana, orchids, potato, coconut, abaca and other forest and fruit trees.

In Palawan, it is quite important considering the distance from other provinces. It is noted that quality plant materials are still coming from other provinces. Putting up a laboratory of this kind would be a great help to our farmers, growers and the province as whole.


General -

Mass production of high quality plant materials for commercial and research purposes.

Specific -

1. To mass produce high quality planting materials;

2. To produce planting materials free of systemic diseases and soil-borne pests;

3. To get uniform plants in the field.

C. Seed Testing Laboratory

A newly established laboratory which shall be responsible for testing the seeds for purity, germination, variety and moisture content to meet quality standard. 

The center was originally part of Brooke’s Point, Palawan as there were two RAC’S established in the municipality (one was in Brgy. Maasin) during the establishment of PIADP in November 1982. It became part of municipality of Española when this municipality was established on July 26, 1993. 

Abo-Abo RAC was approved thru a Brgy. Resolution by then Brgy. Captain Doris Martinez and its councilors requesting the Department of Agriculture – PIADP thru its Project Manager Nestor Arcega Torres, that an agricultural center be considered in Brgy. Abo-Abo because of its far distance from the town proper of Brooke’s Point, Palawan. Among other things stipulated in the resolution was the willingness of barangay to donate 10 hectares (100,00 m2) land from barangay reservation area with Lot No. 643 Pls-618-D to be utilized for that purpose.

In 1983, staff houses and nursery was temporarily constructed and in year 1985, permanent buildings were then erected.

In 1990, when PIADP was terminated and all RAC’s under the program were maintained by skeletal force.

In 1993, all RAC’s were turned-over to local government units except Abo-Abo RAC, which was then retained and put under the administration of DA-STIARC-ROS, Palawan. This was so, because of its research function and strategic location in the southern part of Palawan and ultimately became the satellite station of the DA-STIARC-ROS, Palawan. The RAC is headed by an Officer-in-Charge, Mr. Danilo Jimenez – a DA-STIARC-ROS permanent employee.

Abo-Abo RAC is 400 meters from the National Highway and 130 kilometers from Puerto Princesa City, Palawan.

As satellite station of the DA-STIARC-ROS, the RAC has strategic goals/objectives to perform: 

1. To conduct agricultural researches intended to help farmers improve their production both on crops and livestock;  

2. To produce high quality seeds and plant materials and cater to the needs of farmer in the Southern Municipalities of Palawan;

3. To serve as training facility to students, technicians and planners seeking technical know-how and agricultural updates; to conduct demonstration projects developed through research and development projects.


The Center is a regional facility located at Barangay Irawan, Puerto Princesa City. It is responsible also in the implementation of the Breeder Based Expansion Project (BBEP). A total land area of 222 hectares maintaining cattle, goat, horse and carabao. 

Located at Bgy. Irawan, Puerto Princesa City, a regional facility conducting demonstration in the production of milk. It has a total area of 25 hectares. 

A facility of the Second PIADP and was turned over to the national government under the supervision of DA Region 4. It is located at Kemdeng, San Vicente, Palawan (182 kilometers from Puerto Princesa City). The Center was established in 1998, the total areas 120 hectares maintaining total stocks of 57 heads (6 carabull, 10 caracow, 7 caraheifer, 10 caracalves and 24 yearlings).
