Other claims from this paper (12)
- Method / resource Seed release frequency and flow rate had a linear relationship with R² of 99.57%.
- Method / resource At SRF 12, the population index differed significantly from other values.
- Method / resource Seed rate decreased at SRF of 12 or higher.
- Method / resource Variation in seed flow was at most 2%, except at SRF 4.
- Method / resource Maize seeding precision was below 17% at 14.8–25.5 cm spacing, below the acceptable 29–30%.
- Method / resource Cotton metering indicators at 5.7 cm spacing were below acceptable values and required thinning.
- Method / resource At SRF 20 and forward speed 1 m s, the cotton indicators increased.
- Method / resource At 9.9 cm spacing, feed quality and multiple index were better at 1.0 than 1.5 m s.
- Recommendation A speed under 1.5 m s is recommended for cotton at 9.9 cm spacing.
- Method / resource Seed placement reduced row surface residue from 5600 to 1431.5 daN ha.
- Method / resource Seed placement established an appropriate soil medium.
- Method / resource Weighted average aggregate diameter was 16.4 mm.
