Summary
I markforsøg blev det undersøgt hvorvidt samtidig såning af ærter og vinterkorn kunne øge kerneudbytter i kornet. Princippet i dyrkningsmetoden er at ærterne i løbet af efteråret via biologisk N-binding optager luftens kvælstof, som efter ærternes udvintring friggives til kornafgrøden i det tidlige forår. Sammenfattende kunne det konkluderes, at såfremt der ikke er større udgifter forbundet med anskaffelse af ærteudsæd (evt. ærter af egen avl), kan dyrkningssystemet med fordel anvendes. Specielt i år hvor de klimatiske forhold gør det vanskeligt at udbringe gødning tidligt, vil ”ærte-kvælstof” kunne sikre at kornafgrøden kommer godt i gang.
Summary translation
In field experiments a cropping system with simultaneous sowing of winter cereals and field peas has positive effects on yields of the cereals. The principles in this systems is that the peas fix atmospheric nitrogen during the autumn, die during the winter and release the nitrogen to the cereals in the early spring. Overall, it was conluded that providing that the pea seeds can be obtained at a low cost, the system can be recommended. Especially, in years were the climatic conditions make it difficult to bring out fertilisers early in the spring, the "pea-nitrogen" may ensure a good start for cereals.
