Other claims from this paper (4)
- Association Planting density, fertilizer and their interaction significantly affected corn yield.
- Intervention effect At nitrogen below 25 kg per 667 m2, corn yield increased as planting density declined.
- Intervention effect At a relatively low density of 3 500 plants per 667 m2, corn yield increased with increasing fertilizer content.
- Intervention effect The treatment of 4 000 plants per 667 m2 with 25 kg nitrogen gave the highest corn production, 628.6 kg per 667 m2.
