Other claims from this paper (15)
- Intervention effect At 120 kg N ha-1 under well-watered irrigation, muskmelon biomass was significantly higher than under the two deficit irrigation treatments.
- Intervention effect At 120 kg N ha-1 under well-watered irrigation, fruit yield was higher than under the two deficit irrigation treatments.
- Intervention effect At 120 kg N ha-1 under well-watered irrigation, fruit weight was higher than under the two deficit irrigation treatments.
- Intervention effect At 120 kg N ha-1 under well-watered irrigation, leaf relative water content was higher than under the two deficit irrigation treatments.
- Intervention effect The WS and SWS irrigation treatments reduced all measured parameters except fruit soluble dry matter concentration, compared with unstressed irrigation.
- Intervention effect The WS irrigation regime with 80 kg N ha-1 significantly improved fruit yield and fruit size compared with the SWS regime.
- Intervention effect The WS irrigation regime with 80 kg N ha-1 significantly improved plant dry matter, leaf area and IWUE compared with the SWS regime.
- Intervention effect Increased N significantly enhanced foliar N in unstressed muskmelon plants.
- Intervention effect Increasing N rate in the SWS treatment did not increase fruit yield, unlike the WS and C treatments.
- Observation Water use (ET) at the C treatment with 120 kg N ha-1 ranged between 160 and 165 cm.
- Intervention effect Severe water shortage (SWS) reduced water use (ET) to 90 cm at 0 and 40 kg N ha-1, compared with the C treatment at 120 kg N ha-1.
- Association Nitrogen supply modified water use under the C and WS irrigation regimes.
- Association Muskmelon yield response to N rate was quadratic and differed with the level of irrigation.
- Recommendation A moderate water deficit (SW) with a suitable N rate may be an alternative irrigation choice for muskmelon growers in arid and semi-arid regions, if the goal is to irrigate more growers with limited water, but not if the goal is maximizing economic yield.
- Recommendation Growers should accept a significant yield reduction in exchange for water conservation.
