Research projects

On 1889, the Italian Ministry of Agriculture founded the Experimental Olive Mill in Palmi (RC). About ten years later, the Experimental Olive Mill was transferred to Spoleto (PG), where the researchers mainly lead, for more than 100 years, activities in the field of innovation in the extraction technologies of olive oil. The Experimental Olive Mill, was earlier transformed in Experimental Institute for Olive Growing and corresponding Olive Mill. Then, following the Law 1318/68 the Institute for Olive Growing of Spoleto was transformed into a section of the new Experimental Institute for Olive Growing of Rende while an additional section specialized in table olives was contemporarily added.

In 1999 the Agricultural Research Council (CRA), the Research Agency of the Italian Ministry of Agricultural, Food and Forest Policies, was founded to comprise all the Experimental institutes of Italy. In the 2007, following the CRA internal re-organization, the CRA-Experimental Institute for Olive Growing was transformed into “The Olive Growing and Olive Product Industry Research Centre” (CRA-OLI). 

At present, the CRA is the second greatest public organization of Italy, comprising 15 Research Centers and 33 Research Units, some of which previously independent Research Institutes and already active since at the end of the 19th Century. The Research Centers and Research Units cover a broad range of subjects in the fields of agriculture, animal husbandry, forestry and agroindustry. Some are targeted at specific crops, others at specific products some at “horizontal” disciplines.

At present, a radical reorganization of the research Centers and Units is advanced, with the aim of reinforcing synergies within the present network and focuses resources on critical themes in order to better meet the needs for knowledge and innovation of agriculture and the agro industry. While the CRA is currently undergoing extensive reorganization, the CRA-OLI at present continues its initial research mission on “improvement of olives and cultivation techniques for increase the production of higher grade olive oils, keeping in mind the necessities of olive producers of the agricultural sector of the Country”. The CRA-OLI is divided in two scientific unit in Rende and Città S. Angelo (PE), in addition to a peripheral unit in Spoleto (Perugia). Its research efforts on olives and derived oils involve characterization of cultivars, soil and climatic conditions, plant protection, and cultivation techniques.



The CRA-OLI has research projects that are financed by the European Community, the Ministries of University and Research and Agriculture, Food and Forest Policies, as well as the Italian Regions. In particular, in 1999-2000 years it coordinated a research project entitled “Characterization of the quality of olive oils produced in southern Italy from olives cultivated by organic methods”, which involves the major olive producing regions in the South of Italy (Apulia, Calabria, Sicily, and Sardinia). It was responsible for a special, integrated research project co-funded by the Italian Ministries of University and Research and Agricultural and Forest Policies, entitled “Valorisation of typical products: definition of parameters and techniques for certification of origin and quality”. The CRA-OLI is presently responsible for general coordination of a research program sponsored by the Ministry of Agricultural, Food and Forest Policies on organic cultivation techniques, comprising seven research projects, and also directs one of these. More recently, it coordinate a large research project entitled

“Research and innovation for the olive growing of the South” (RIOM) which involves all the olive producing regions in the South of Italy (Apulia, Calabria, Sicily, Basilicata and Campania), funded by the Ministry of Agricultural, Food and Forest Policies. Numerous research publications have stemmed from these research efforts. The Institute has significant experience in scientific and technological innovation and it is at the forefront of new cultivation techniques, propagation methods, pest and disease management strategies, production of table olives, analytical methodologies, genotype and place of origin traceability, all belonging the olive/olive oil chain. The Institute has notable interdisciplinary scientific skills with researchers in Chemistry, Agricultural and Biological Sciences, as well as technicians in agricultural methods with extensive experience in olive cultivation. Lastly, many staff members, including researchers and technicians, are also professional taste-testers of olive oils and are members of the national register of taste-testers as experts on the sensorial evaluation of olive oil.

The research activity of the CRA-OLI comprise:


a) Characterization of varieties and its products and Genetic Improvement:
1) Selection, description, and evaluation of old and new olive varieties.  This research has recently been updated to take account of the continual discovery of new and interesting genetic accessions, even in very old olive groves, and for the classification of material selected in previous years.
2) Identification and valorization of Italian olive varieties.  The research is aimed at:

1) morpho-bio-agricultural characterization of the large varietal collection at Mirto Crosia (Cosenza);  2) study of DNA polymorphisms (microsatellite loci, SSR); 3) applied chemometric analysis of the various components of monovarietal olive oils (fatty acids, phenols, and volatile compounds).

3) Olive resistance to biotic and abiotic stress and isolation of tolerant plants.  This research was reevaluated in 2002 and has permitted the isolation of varieties resistant to drought, salt, cold, and verticillium wilt.


b) Propagation and cultivation techniques:

1) Study of agricultural problems relative to irrigation and fertirigation. Research reassessed in 2002 that will continue for at least one more year.

2) Resistance of olives to brackish water. This research will continue for another year to determine the effects of the use of brackish water for irrigation of olive groves.

3) Tests on planting grass in olive groves. These analyses examining the influence of land management (controlled sowing of grass seed and mechanical intervention) carried out and extended to other olive growers with different subsoil and soil conditions in Calabria and Sicily.

4) Comparison between types of olive cultivation. These evaluations will continue, assessing growth and production of five cultivars grown in vases or as monocones to initiate studies on production efficiency.

5) Micropropagation of olives. Research aimed at better understanding of micropropagation.

c) Biology:

Mycorrhiza in olives. This research area has been recently strengthened with the availability of a dedicated fellowship.


d) Defense:

1) Integrated defenses against Bactrocera oleae (Gmel.) using alternative methods also compatible with organic farming. This research is targeted at integrated defenses that are both eco-compatible and suitable for organic farming techniques. The project has the objective of evaluating the environmental impact of various treatments and determining the presence of eventual residues of treatment products.

2) Assessment of the diffusion of verticillium and peacock spot disease. Study of etiologic

mechanisms and sources of resistance This research has the major objective of optimizing defense against Verticillium, peacock spot, and Cercosporiosis.

e) Products and byproducts:

1) Production of green olives using alternative methods This research involves measurement and verification of chemical, microbiological, and organoleptic parameters of olives and packaging brine of various Italian varieties subjected to different manufacturing systems.
2) Traceability of Italian olive oils. Construction and validation of chemometric models that are able to characterize, classify, and individuate the most widespread Italian olive oils through multivariate statistical analysis of multivariety and monovariety olive oils.
3) Tests on composting olive mill wastes. Residual oil and vegetable water added to bedding and ground cuttings subjected to composting. The compost is then distributed over olive fields. Various assessments are made on olive plants to reveal the effects of this treatment.
