Strengthen the cultivation of legumes

How well is a combination of maize and beans suited as a feedstuff for dairy cattle and fattening pigs? This topic was studied by our scientists in Trenthorst. (Video in German)

Legumes or pulses are not only an extremely diverse group of plants, they also have many useful properties – but the cultivation of legumes, however, is not easy

From choice of site to aphid infestation - many factors determine whether legumes flower and prosper. We give tips for growers

The cultivation of legumes is declining in many European countries for many years, despite of a lot of positive properties, but they are usually economically not competitive with other crops. Therefore, cultivation systems with legumes need to be evaluated and developed further on.

In the future, the amount of on-farm or locally produced feedstuff should increase to ensure a sustainable protein supply for farm animals. In our project we analyze the potential of the mixed cropping of maize with runner or scarlet runner beans.

Legumes are essential in the system of organic farming because of the nitrogen fixation and their function for the nutrient supply. They improve soil fertility, and provide a protein-rich feed stuff. In field trials with the focus of mixed cropping of grain legumes, especially the cultivation of blue lupins and peas we focused on yield optimisation and weed management. , We also evaluated the feed quality and their contribution to protein supply in organic animal husbandry.

The agricultural advantages of mixed cultivation in low-input-systems are often demonstrated for the higher yield stability, a more effective weed suppression and a better use of the growth factors light, water and nutrients. We wanted to evaluate in the system of organic farming the mixed cropping especially under a simultaneous reduced intensity of soil cultivation in constricted crop rotations with grain legumes.
