Other claims from this paper (8)
- Observation Water use by wheat peaked at 15 to 20 L m-2 d-1 up to Day 40 in both culture systems.
- Association Water use declined more rapidly in ZPT culture than in hydroponics after Day 40, attributed to earlier leaf senescence.
- Association No consistent differences in water status were noted between wheat in the two culture systems.
- Intervention effect Harvest index was 28% lower for wheat grown in ZPT than in hydroponic culture.
- Intervention effect Yield of wheat was similar in ZPT and hydroponic culture.
- Mechanism Biomass partitioning differences in wheat were attributed primarily to NH4-N nutrition in ZPT versus NO3-N in hydroponics.
- Mechanism NH4-N-induced calcium deficiency probably produced excess tillering and lower harvest index in ZPT wheat.
- Recommendation Further refinement of zeoponic substrate would make ZPT culture a viable alternative for high productivity in a CELSS.
