Räpi experimental farm – a pioneer in cultivation expertise in satakunta
The operations began in 1954 as an experimental farm for Länsi-Suomen Sokeritehdas Oy and they have continued uninterrupted to the present day, with Räpi serving as an experimental farm for Lännen Tehtaat and Apetit. Today, as one of only a few company-owned experimental farms in Finland, it contributes to the development of agricultural expertise in Satakunta.
Throughout its history, the Räpi experimental farm has served as a channel through which new plant varieties and cultivation methods enter the Satakunta region. The cultivation methods, plant varieties and focus areas of research have changed over the years. The experimental activities began with experiments related to sugar beet varieties and cultivation methods. They were later expanded to cover many other outdoor crops when Lännen Tehtaat began the contract growing and production of a wide range of frozen vegetables in Säkylä.
The research done at Räpi is aimed at anticipating future trends in outdoor crop cultivation. For example, all the plant varieties and cultivation methods selected for use in Apetit’s contract growing are tested at Räpi before their broader implementation. This season, the farm has tested plant varieties, fertiliser use and cultivation methods for peas, swede, parsnip, carrot, spinach, celeriac, sugar beet and other crops.
Experimentation promotes vegetable quality and sustainable growing
During the past decade, the research and experimentation at Räpi has been particularly focused on developing a cultivation method that supports a sustainable and environmentally friendly farming ecosystem. The most recently-developed cultivation methods are based on using plant protection measures only when necessary and only to a limited extent. Biological and mechanical solutions are prioritised.
Pest control solutions can include, for example, nets that cover crops, and information on pest life cycles and their natural enemies. Similarly, biodegradable covering materials and mechanical uprooting can be used to control weeds.

The delicious taste of Apetit frozen vegetables comes from expert farming and superior varieties
The Räpi experimental farm is constantly testing new varieties to find those with the best flavour, texture, nutritional quality and suitability for freezing for use in Apetit products. Apetit’s product development also guides choices related to plant varieties and contract growing. The popularity of Apetit Kotimainen, a product range focused on vegetables grown in Finland, supports introduction of new varieties to contract growing in Finland.
A hub for developing Finnish integrated production expertise
The results of the research at Räpi experimental farm are used in the development of the Apetit farming method to which all of Apetit’s contract growers are committed. The Apetit farming method is used to manage plant-specific cultivation instructions, quality and product safety, and other factors. For example, plant protection measures are only used when necessary and with due consideration. The Räpi experimental farm plays a key role in Apetit Farming method.
The Räpi farm has contributed significantly to development of the Finnish IP (Integrated Production) method. In 2011–2013, it participated in the Varjellen Viljelty project by updating new plant-specific cultivation instructions in response to consumer expectations and regulatory standards.
The Räpi experimental farm cooperates closely with the Pyhäjärvi Institute, Natural Resources Institute Finland, Åbo Akademi University, the Sugar Beet Research Centre of Finland and growers in the Satakunta region. The new knowledge and expertise developed at Räpi is transferred to Apetit’s approximately 150 contract growers in many ways. Those include the Experimental Farm Days event, which promotes the success of agriculture as a livelihood throughout Satakunta.

Roots on Lalli manor lands
The written history of the Räpi experimental farm began in 1156, when it was part of Lalli Manor. In 1812, the Kepola country manor was separated from Lalli Manor. More than a century later, in 1917, the Kepola country manor was split into three parts and divided between the owner’s sons. The youngest son, Albert, stayed on as landlord of one of the three parts, which was subsequently named Räpi.
After the war, the family’s youngest son, Jaakko Rauanheimo, became the new landlord of the Räpi estate. He held this position until 1954, when he sold the farm to Länsi-Suomen Sokeritehdas Oy, which had been established in Säkylä in the early 1950s.
