The goal of an one-year field experiment was to examine the influence of different sowing dates (autumn vs. spring) on crop development, yield and yield structure of wheat (cv. Xenos), triticale (cv. Agrano, Trimmer), einkorn (cv. Terzino) and pea (cv. Cherokee) under growing conditions of the Marchfeld plain (Pannonian climate region). This experiment concentrated on following questions: to what extend did the sowing date and the species or variety influence the (1) crop development, (2) yield and yield components, (3) the nitrogen content and uptake and (4) how the crops are influenced by the longer growing period and different climate conditions between autumn- and spring-sowing. Due to the extraordinary drought in spring 2012 the ripening of all examined crops was accelerated. Autumn-sown wheat and triticale (sowing: October 18th, 2011) as well as the autumn- and spring-sown peas (sowing: March 13th, 2012) were harvested on the same day (3rd July, 2012). Spring-sown wheat and triticale as well as the autumn- and spring-sown einkorn were harvested on 11th July, 2012. Nevertheless, the autumn-sown crops showed a higher crop stand height and higher biomass production throughout crop development compared to the spring-sown crops. The advance of plant development of autumn-sown crops also had a positive effect on the yield components and nitrogen yield. These crops produced higher above-ground biomass yields, higher harvest indices, higher thousand grain weight and had an increased nitrogen yield and nitrogen use efficiency. Furthermore autumn-sown cereals developed more ears per square metre. Even the pea plants which showed the most evident symptoms of stress (stunted growth, reduced fructification, atrophied pea pods) due to drought showed a better performance when sown in autumn than in spring.
