This data set reports measurements and observations from a grain legume cropping system experiment (2017-2021) investigating the effects of cultivars and irrigation on yield of soybean, lupins and faba bean, and rotational effects on a subsequent winter wheat (2018-2020). The objective was to identify grain legume species and cultivars for designing novel cropping systems in north-eastern Germany. The data supports agronomic analyses, as well as dynamic simulation modelling and includes details on crop growth, soil characteristics and weather.
In the first part of the experiment different species and cultivars and the effect of irrigation were compared in a split block design with four replicates and the factors species/cultivar and irrigation during five consecutive years (2017-2021).
In the second part of the experiment, the pre-crop effect of soybean narrow-leafed lupin, white lupin and buckwheat was tested on the grain yield and nutrient content in the following winter wheat crop and on the nitrogen dynamics in the soil. Before winter (November/December) and in the subsequent spring (February/March), mineral nitrogen was measured in the soil at three depths (0-30 cm, 30-60 cm, and 60-90 cm) after the different pre-crops. Winter wheat was established following the different pre-crops with 4 replicates during three consecutive years (2018-2020) with conventional fertilization and crop protection.
