Other claims from this paper (8)
- Intervention effect Leaf blade, leaf sheath and culm nitrogen percentages were highest with topdressing, then foliar application, then no topdressing; this order held across varieties and basal nitrogen levels.
- Intervention effect Ear nitrogen percentage was highest with foliar urea, then topdressing, then no topdressing.
- Association Nitrogen accumulated in the ear increased with the basal nitrogen amount.
- Intervention effect The rate of nitrogen accumulation in the ear was higher on foliar application plots than on the other plots.
- Intervention effect Brown rice protein percentage was highest on foliar application plots.
- Intervention effect Brown rice protein percentage increased by 9∼13% on foliar application plots compared with topdressing plots.
- Intervention effect Brown rice protein percentage increased by 31∼34% on foliar application plots compared with non-topdressing plots.
- Intervention effect Foliar urea application significantly increased brown rice protein percentage regardless of cool-summer damage.
