EFFECTS OF BARNYARDGRASS ON NITROGEN CONTENT, NITROGEN QUOTA IN ABOVE-GROUND PLANT ORGANS AND SEED PROTEIN YIELD OF SOYBEANS UNDER DIFFERENT WATER STRESS CONDITIONS
Abstract:Barnyardgrass(Echinochloa crus-galli) interference significantly reduced the seed protein yield and the nitrogen quota in seeds of soybeans, but markedly increased the nitrogen content in its leaves, stems and seeds as well as the nitrogen quota in its le
