Other claims from this paper (13)
- Intervention effect Irrigation and nitrogen levels significantly affected the measured shallot growth, yield, water use efficiency, and nitrogen uptake parameters.
- Intervention effect The irrigation by nitrogen interaction significantly affected the parameters other than bulb number and nitrogen uptake.
- Intervention effect The irrigation by nitrogen interaction did not significantly affect bulb number or nitrogen uptake.
- Association Each additional millimetre of irrigation increased total bulb yield by about 0.0209 t ha-1.
- Association Each additional kilogram of nitrogen increased marketable bulb yield by 0.022 t ha-1.
- Association Each additional kilogram of nitrogen increased total bulb yield by 0.0158 t ha-1.
- Intervention effect At 120% ETc irrigation with 105 kg N ha-1, marketable bulb yield was 11.64 t ha-1, among the maximum yields.
- Intervention effect At 120% ETc irrigation with 151 kg N ha-1, marketable bulb yield was 12.03 t ha-1.
- Intervention effect At 120% ETc irrigation with 105 kg N ha-1, total bulb yield was 12.91 t ha-1.
- Intervention effect At 120% ETc irrigation with 151 kg N ha-1, total bulb yield was 13.3 t ha-1.
- Recommendation The authors considered 100% ETc with 151 kg N ha-1 the best treatment for water use efficiency.
- Intervention effect Yield under the water use efficiency preferred combination was significantly below the maximum yields.
- Intervention effect Nitrogen application of 151 kg N ha-1 gave the highest total nitrogen uptake, 37.18 kg ha-1.
