Other claims from this paper (9)
- Intervention effect Without irrigation, increasing nitrogen did not affect onion growth, maturity, or final yield.
- Intervention effect With weekly rainfall plus irrigation, increasing nitrogen increased onion growth to midseason and final yield.
- Intervention effect With weekly rainfall plus irrigation, increasing nitrogen advanced onion maturity.
- Intervention effect High nitrogen advanced sprouting in storage relative to no or low nitrogen.
- Association Irrigation strengthened the nitrogen effect on storage sprouting.
- Intervention effect Nitrogen topdressing without irrigation did not induce an onion response despite regular rainfall.
- Intervention effect With irrigation, 22 or 34 kg N/ha after each 10 cm water gave the highest onion yield.
- Intervention effect With irrigation, 22 or 34 kg N/ha after each 10 cm water gave earliest onion maturity.
- Intervention effect Nitrogen applied after mid-July gave no yield or maturity advantage.
