- Observation Cover crop biomass ranged from 4.25 to 90.20 kg ha(-1).
- Observation Cover crop N uptake ranged from 0.34 to 133.80 kg ha(-1) N.
- Intervention effect Microbiological fertilizer significantly increased residual mineral N.
- Intervention effect Without cover crops, main crop chlorophyll was significantly lower.
- Observation Fodder kale cover crop had the highest sweet maize yield, 7263.83 kg ha(-1).
- Observation Field pea cover crop had high sweet maize yield, 7177.27 kg ha(-1).
- Observation Winter oat cover crop had low sweet maize yield, 6802.47 kg ha(-1).
- Observation Common vetch cover crop had low sweet maize yield, 6184.14 kg ha(-1).
- Observation Cover crops were more effective for investigated traits, especially yield, in the dry year.
- Observation Microbiological fertilizer was more effective in the dry year.
- Recommendation Authors recommend controlling N by sowing main crops after cover crops in semiarid biological farming.
