Fig. 1 Mean temperature and precipitation in 2021/2022. and indicate precipitation and mean temperature in 2021/2022, and indicate average precipitation and average of mean temperature for average year. I, II, III, IV, V, VI and VII in growth stage indicate for emergency stage, regeneration stage, tillering stage, elongation stage, heading stage, milky stage and maturing stage.
Fig. 2 The leaf area index (LAI) of plant and canopy (A), and chlorophyll content and photosynthesis yield (B) of O-free treated with three N fertilizations in the growing season. N0, N1, and N3 represent additional N fertilization levels, N0 indicates 40 kg/ha additional N fertilization at the regrowing stage, N1 indicates 40 kg/ha additional N fertilization to N0 at the elongation stage, N2 indicates 40 kg/ha additional N fertilization to N1 at the booting stage. I, II, III, IV and V in growing stage mean elongation stage, booting stage and 7-day after flowering (DAF), 21-DAF and 35-DAF, respectively. Bars and dots with different letters above are significantly different at p<0.05.
Fig. 3 The dry weight and nitrogen content of leaf (A), stem (B) and spike (C) of O-free treated with three N fertilizations in the growing season. N0, N1, and N3 represent additional N fertilization levels, N0 indicates 40 kg/ha additional N fertilization at the regrowing stage, N1 indicates 40 kg/ha additional N fertilization to N0 at the elongation stage, N2 indicates 40 kg/ha additional N fertilization to N1 at the booting stage. DAF in ripening stage means day after flowering. Bars and dots with different letters above are significantly different at p<0.05.
