The aim of this project is an accelerated emergence under the local cool spring conditions and a strong youth development of soybean seedlings, which shall lead to high and stable soybean crop yields.
Project
Project code: 2814EPS021
Contract period: 09.03.2015
- 08.03.2018
Budget: 159,739 Euro
Purpose of research: Applied research
The overarching objective of the project is to achieve a rapid and vigorous youth development of soybeans by priming (pre-soaking in water) and seed additives and to convert them into a practice-ready process. Both strategies are already being used successfully in practice in other crops and their effects have been scientifically proven.
In various pot and germination experiments different duration of primming and different seed additives were tested. In a subsequent 2-year field trial, the "best" duration of primming (12 hours) and the best seed additive (Mykoplant) were investigated. The youth development as well as the further plant development up to the harvest were recorded.
It has been shown that the selected type of hydropriming, as well as various variants thereof, leads to a reduction of germination capacity in soybeans and influences youth growth more negatively than positively. Some positive effects could be shown with the seed additives, however these are too small for practical relevance.
The results were presented at numerous conferences as posters or talks and discussed with other researchers. The field trial was presented and discussed in both years during field days. Within the framework of the project, a Bachelor's and a Master's thesis could be realized.
A systematic literature review will evaluate the published studies on hydropriming in soybeans comprehensively and quantitatively and thus contribute to a considerable gain of knowledge in this field.
