Abstract:
A two-year trial (2013/14 and 2014/15) with winter legumes (winter peas and winter faba beans), spring legumes (spring peas and spring faba beans) and control crops (winter oats and winter wheat) was performed on the Experimental Farm Groß-Enzersdorf in the region Marchfeld. The aim of this study was to compare the agronomic parameters of winter legumes with spring legumes. Analyses of the parameters winter survival, yield, yield structure, nitrogen fixation of the plant and in the soil were done. For the experiment, two winter faba beans and a spring faba bean variety were sown in different seed rates. Furthermore, six winter pea varieties and a spring pea were sown. The reference crops for nitrogen fixation performance and overwintering were winter wheat and winter oat. As a result of mild winters 2013/14 and 2014/15, there was almost no winter kill of the winter forms. The dry matter yields and grain yields of winter varieties were both in winter peas as well as in winter faba beans significantly higher than in the spring form of the crops. Different seed rates of winter faba beans showed that halving seed rates caused only low impact on yields, as the lower seed rate was offset by more shoots per plant and pods per shoot. For the spring faba bean variety, this compensation by yield structure could not be obtained during the shorter growing season. For the nitrogen concentration, there were only small differences between spring and winter forms, but the nitrogen yields of winter varieties were significantly higher. The nitrogen content in the soil was also significantly higher compared to the reference crops. However, a positive nitrogen balance could only be obtained by few legume varieties. The results of this experiment showed that winter legumes are a very good alternative to the spring forms, provided that the winter temperatures do not fall too low. Due to the longer growing season and higher yields, lower seed rates can be compensated.
