Nitrogen Yields and Biological Nitrogen Fixation of Winter Grain Legumes

Grain legumes are valuable sources of protein and contribute to the diversification sustainability agricultural systems. Shifting sowing date from spring autumn is a strategy address low yields grain under conditions climate change. A two-year field experiment was conducted Pannonian in eastern Austria assess nitrogen yield biological N2 fixation winter peas faba beans compared their forms. The were 1.83-fold 1.35-fold higher forms, respectively, with value for peas. This mainly due legumes, as had 1.06-fold concentration than bean. Soil mineral nitrate after harvest similar all by 2.85- 2.92-fold values cereals, respectively. 3.90-fold 2.28-fold having 1.60-fold beans. negative balance smaller that they demonstrated ability overcompensate removal through fixation. cultivation especially peas, can be recommended achieve high levels
