Other claims from this paper (7)
- Intervention effect Green manure and rice straw nitrogen, alone or in combination with inorganic N, gave lower grain yield, agronomic efficiency and apparent nitrogen uptake than a standard split application of prilled urea.
- Intervention effect Compared with prilled urea, residual effects of green manure or rice straw included a significant increase in soil organic carbon and total nitrogen.
- Intervention effect Residual effects of green manure or rice straw, compared with prilled urea, included greater extractable soil nitrogen in the vegetative growth period.
- Intervention effect After panicle initiation there was no residual effect of previous nitrogen source on the rate of crop nitrogen accumulation.
- Intervention effect Final grain yields were similar regardless of the previous nitrogen source.
- Intervention effect The increase in soil nitrogen from rice straw was 50-150% greater than from green manure.
- Intervention effect The efficiency of rice straw nitrogen combined with prilled urea is comparable to green manure nitrogen.
