Other claims from this paper (8)
- Intervention effect Phosphorus alone had no significant effect on maize yield.
- Intervention effect Nitrogen alone or with phosphorus increased maize yield and nitrogen content.
- Intervention effect Maize yield did not significantly depend on nitrogen form or split application.
- Intervention effect Sodium nitrate and ammonium nitrate applied about ten weeks after sowing had about 58% nitrogen uptake.
- Intervention effect Ammonium sulphate and urea applied about ten weeks after sowing had about 39% nitrogen uptake.
- Intervention effect Foliar urea was used nearly as efficiently as sidedressed urea.
- Intervention effect Before-sowing fertilizers were at least nearly as efficiently used as sidedressed fertilizers.
- Intervention effect Adding 120 kg N/ha raised maize soil nitrogen uptake by 33%.
