Other claims from this paper (19)
- Observation Soil nitrate and ammonium were highest at 0–10 cm two days after application.
- Observation After 28 days soil nitrate peaked at 20–40 cm.
- Observation After 28 days soil ammonium remained highest at 0–10 cm.
- Intervention effect DIO increased aboveground and root biomass compared with DIS.
- Observation Root biomass at 0–10 cm exceeded 10–50 cm in both irrigation regimes.
- Intervention effect Under DIO, HN and AN increased deeper root biomass versus MN.
- Intervention effect Under DIS, deeper root biomass did not differ significantly among MN, HN and AN.
- Intervention effect DIO increased rice N accumulation relative to DIS.
- Intervention effect AN had the highest rice N accumulation.
- Intervention effect LN had the lowest rice N accumulation.
- Intervention effect DIS increased PrNTA and PrNTC relative to DIO.
- Intervention effect DIS reduced PoNAA and PoNAC relative to DIO.
- Intervention effect DIS reduced panicle number, spikelets per panicle and seed-setting rate.
- Intervention effect Under DIS, yield parameters did not differ significantly among MN, HN and AN.
- Intervention effect Under DIO, HN and AN produced similar seed set, grain weight and yield.
- Intervention effect Under DIO, HN and AN exceeded MN and LN for seed set, grain weight and yield.
- Intervention effect DIO increased NPFP relative to DIS.
- Intervention effect AN had the highest NPFP and LN the lowest.
- Recommendation Increasing nitrogen and ammonium nutrition can improve drip-irrigated rice yield, though limited irrigation may constrain further gains.
