Green manures are an alternative to improve nitrogen availability for plant nutrition in a global context of declining soil fertility. To investigate the effects of green manure and nitrogen fertiliser on maize yield under the Braila Agricultural Development Research Station conditions, a bifactorial experiment with four replications was conducted for two years. The main factor was the use of green manures at four levels (control - without green mulch crop; winter pea (Pisum sativum L. var. arvense.); white mustard (Sinapis alba L); winter rye (Secale cereale L.), while the sub-factor was the application of N fertilizer at four levels (0, 60, 90 and 120 kg/ha of N active substance). Green manure application significantly influenced corn yield, with increases of 19.4% for winter pea, 16.9% for white mustard, and 9.8% for rye. The same significant influence was found on plant height and yield components. The application of different levels of nitrogen also had a very significant influence on yield results and yield components.
