- Abstract:
- In the vegetation period 2016/2017 a field trial has been carried out in Raasdorf (Marchfeld). The aim of the experiment was to determine the plant parameters of winter grain legumes compared to spring grain legumes. Parameters such as overwintering, yield, yield structure, nitrogen yield and nitrogen fixation were analyzed. Wheat served as a reference plant to determine the nitrogen fixation performance. The overwintering of grain legumes was pretty good and led to a high crop density, which could not have a positive effect on the yield of field bean due to the low rainfall during flowering and the grain filling phase. The yield advantage of the vegetation lead in winter crops could not be confirmed in the field bean. This positive effect could be exploited in peas, whereby the winter form was able to achieve better results in almost all parameters. In the case of nitrogen yields, the winter forms of pea and wheat were able to achieve the best values for grain and aboveground biomass. In field bean, the spring form achieved better values. The nitrogen content in the soil was always higher in legumes compared to the reference plant, yet no culture achieved a positive N balance. Conclusion of the experiment is a high suitability of winter legumes as an alternative to summer legumes mainly for pea. The Field bean suffered from missing precipitation at crucial stages of development and obtained only a lower yield than the spring field bean.
