Abstract:
The goal of a one-year field experiment in Raasdorf was to examine the influence of different sowing dates under production conditions of the Marchfield cropping area. Wheat (cv. Xenos), pea (cv. Cherokee), Einkorn (cv. Terzino) and triticale (cv. Agrano, Trimmer) were planted on two different sowing dates (autumn versus spring). This experiment concentrated on following questions: to what extend did the sowing date and the species or variety influence (1) crop development, (2) aboveground biomass growth and yield structure, (3) intercepted radiation and (4) mineral nitrogen content in the soil? The autumn sowing date (sowing: Oct. 7, 2010) reached maturity earlier, it generally increased plant high and also soil cover because of the advance of plant development compared to the spring sowing date (sowing: March 14, 2011). The crops produced higher aboveground biomass yields, higher harvest yields and also more ears or pea pods per square meter when sown in autumn than when sown in spring. The 1000 seed weight and the grain dry matter of wheat, pea and triticale confirmed these advantages of an early sowing date, Einkorn did not show this positive effect. The absorbed radiation was in general higher with autumn sown crops than with spring sowing. Spring sown crops showed a higher mineral nitrogen content in the soil in April 2011 and at the end of May 2011. An earlier crop development, higher yield components and more absorbed radiation of wheat, pea, Einkorn and triticale sown in autumn show, that an earlier sowing date under production conditions of the Marchfield cropping area is preferable to a late sowing date and that the planting of crops in spring is inferior to the autumn sowing date. Many advantages of the pea cv. Cherokee in the autumn sowing date, as shown in the results of this experiment, indicate that there is a big potential of this cultivar sown in autumn.
