Abstract:
An intercropping experiment was performed in 2016 and 2017 with wheat and grain legumes (field beans, peas and lentils) on the experimental farm Groß-Enzersdorf of the University of Natural Resources and Life Sciences in the region Marchfeld. Wheat was intercropped with one of the grain legumes in three different mixed proportions. The aim of the trial was to find out the differences between the mixed and the pure cultures. The observed traits were yield, yield structure, nitrogen content (N), yield of N and the N fixation of crops in pure culture and in intercrops. Therefore, the following parameters were analysed: soil coverage, plant height, above-ground biomass, absolute and relative growth rates, yield and yield components. In ad-dition, the amount of soil mineral N and soil water was assessed and N uptake rates and N yields were determined in 2017. In general, the grain yield was in 2016 (+19 %) significantly higher than in 2017. An increase of wheat in the intercrops resulted in a decrease of the yield of the grain legumes. Across all legumes, the field beans had the highest yield. All parameters which had been investigated showed that field beans were not suppressed by wheat as much as peas and lentils. The comparison of the intercropping proportions showed that wheat within the wheat-lentil-mixture had the highest grain yield. The intercrops with field beans and peas were much more competitive to wheat than the intercrops with lentils. The pure cultures of the leg-umes attained a higher grain yield than the intercrops. Another result is that the concentration of nitrogen in the grain of wheat in mixtures was higher due to a lower population of wheat. There were significant differences in the nitrogen content. The pure cultures of wheat and leg-umes showed higher nitrogen levels than those in the mixtures. The comparison of pure and mixed cultures did not show a difference in soil mineral N at harvest.
