Improvement of the ecological fresh plant production and determination of a possible ecological mother plant keeping of strawberries

Project


Project code: 2811OE039
Contract period: 15.03.2012 - 31.07.2015
Budget: 201,008 Euro
Purpose of research: Applied research

The effect of different substrates, pots, fertilisation and varieties of strawberry fresh plants were analysed at the chamber of agriculture NRW, Germany, in a one and two factorial field experiment during the seasons 2012 to 2015. The aim of this work was the development of good and ecological cutting substrates for producers and farmers of strawberry plants. The analyses were performed with the varieties Elsanta (2012 to 2015) and Flair (2014 to 2015). Up to 18 different treatments were tested. The standard method (6 cm pressed pots) and a conventional treatment were compared with up to 7 different ecological cutting substrates. The quality of the strawberry fresh plants from the substrates was high to very high. There were significant differences between the fresh plants after the development time of four weeks for the rooting, but the results differed from year to year. The pressed pots showed the lowest quality in all three years. There was a direct relationship between the quality of fresh plants and the development of the plants in the field as well as the yield the year after. 4 cm trays were optimal for the development during the growing period. Cutting substrates of peat or coco are possible. The percentage of compost should be between 10 and 20 %. A second theoretical part shows if an ecological mother plant keeping system is possible. Therefore farmers, producers of strawberry plants, scientists and ecological inspection bodies were interviewed, the mother keeping system was described and recommendations were given. Diseases and pests and their control were described.
