Other claims from this paper (10)
- Intervention effect Irrigation on the day ponded water disappeared gave the maximum grain and straw yield, on a par with irrigation one day after.
- Intervention effect Among nitrogen-management practices, 150 kg N/ha in 4 splits with green manure gave significantly the highest grain and straw yields.
- Intervention effect Number of panicles, spikelets and filled grains followed the same trend, highest with 150 kg N/ha in 4 splits with green manure.
- Intervention effect Spikelet sterility and single grain weight were not affected by irrigation treatments.
- Intervention effect At N levels above N0, spikelet sterility fell by 2.0 to 2.5%.
- Intervention effect Applying N in 3 or 4 splits helped reduce spikelet sterility.
- Intervention effect Applying N in 3 or 4 splits significantly improved grain weight.
- Intervention effect Irrigation regimes, with irrigation on the day ponded water disappeared or one day after, significantly enhanced N uptake equally.
- Intervention effect Higher agronomic efficiency was recorded with irrigation on the day ponded water disappeared together with 4 splits of N plus green manure.
- Intervention effect Maximum water-use efficiency was obtained with an irrigation interval of 3 days after disappearance of ponded water plus 4 N applications with green manure.
